ABSTRACTt In this paper the investigation of the total kinetics of this
cracking between 800 and 900 0 is descAbed. The increase of tempeie,
ture and the corresponding rapid shortening of the reaction IL-riod
from 0,5 to 0,005 seconds demand a special experimental rm thod.
The experiment was divided into 2 partst 1.) the cracking itsief
and 2.) analysis of the products. In the case of the latter a chro-
matographical method worked out by the authors.was used (reference
3), where this method failed because of 'the small quantity of the
single gases (e.g. isobutane), the me thod of radioactive indicators
was used. n addition to that, a small quantity of methane, mark-
T
ed with C
4, was added to the inlial ethane. Fi~rure 1 gives the
arrangement of the basic elements of the experimental device. Dur-
ing the experiments a "bailing layer" (reference 2) was produced in
the reactor. After a quick cooling of the craoking products after

ABSTRACT: The present paper investigates the portion of chain reactions
in the cracking of ethane in the temperature interval 770-
goooC. This problem is at present intensively investigated
for low temperatures (references 1, 2, 3, 8). But the mechanism
of the cracking and of the pyrolyses is not to be considered
as finally determined, especially not at the high temperatures
used in engineering. Por solving this problem the authors made
measurements of the activities of the different products ob-
tained in the crjaking of a mixture of ethane with methane
(labelled with C ). The method of these tests was already
described in an earlier work (referenSe 5). The data obtained
for the temperatures 770, 84o and 89o C are illustraded in a
diagram. The testa discussed here were performed in the case
of complete or almost complete intermixture in the "boiling"

additionally includes 5 elementary processes in the
examination. Then the expressions for the dependence of the con-
centrations of the various active products on time, obtained
due to a special analysis, are given. A provisional estimation
already shows that the portion of chain reactions in the total
process of cracking within the frame of the generally used
scheme in the case investigated here is very small. Detailed
numerical data on this are given. There are I table, and 9

(USSR)
ABSTRACT: The reaction mechanism of the cracking of hydrocarbon gases
at 770-8900 was studied-f as in general the industrial pyrolysis
of these gases takes place at these high temperatures. A
special experimental method was developed by which tracer atoms
and ethane are used to which approximately 2% of marked C14H4
methane was added. The experiments were made in a con-
tinuously working apparatus (Fig 1) at approximately 90 = H&
The quartz reactor was filled with corundum acting as heat
carrier, and the temperature was recorded by means of an
EPP-49 electronic potentiometere The results obtained (Ta-
bles 1-3) showed that at these temperatures the maximum par-
ticipation of the chain-reaction process in the conversion of
Card 1/2 ethane into ethylene is 5%, and that the inherent inhibition

characteristic of cracking at 500-6500C does not occur. The
reaction proceeds according to the first order, and the ac-
tivation energy is 82+2 kcal/mol. The reaction-rate constant
of CH3 + C2 H6 --->CH4 + C2H5points to a steric factor of the
order of 10-3 for this reaction, while the activation energy
obtained from 12+2-kcal is in agreement with data from other
publications. The recombination constant, obtained both by ex-
periment and by calculation using thermodynamic data, is ap-
proximatelY 5-10 2 times smaller than that obtained at lower
temperatures. The decomposition rate constant of the ethyl
radical is jo3 times smaller than it would be according to the
elementary kinetic gas theory. There are 4 figures, 3 tablesj

Doklady Akademii nauk SSSR, 1959, Vol 124, Nr 2, PP 340-341
(USSR)
The present paper deals with the intensity of the isotopic
effect in the cracking of ethane marked by C 4. Different
results obtained by previous papers are mentioned in short.
The authors investigated the cracking of the mixture
C12H3 - C 12H3 and C12H3 - 014H3 at high temperatures. The
decomposition mechanism of ethane is considerably more simple
than that of propane. The experiments were carried out at a
temperature of - 8500 and at pressures of 50-80 torr according
to an already previously (Refs 5,.6) described method in a
reactor with practically complete mixing. The results obtained
by the experiments show the following: In a wide interval of
degrees of transformation the activity of the produced
ethylene does not differ from the,activity of ethane

On the Isotope Effect in the Cracking of Ethane SOV/20-124-2-28/71
(accuracy ~ 1 %). The activity of methane is not equal to A/^
(as it would have to be in the case of lacking isotopic effect)
but much lower. Here A is the activity of the ethane mixture
existing when measurements were begun. A table contains the
values of ethanii activity in % of A/2 as function of the
ethylene content in the cracked gas. Methane acti4ity is
lower by - 10 % than A/2 and varies relatively little with
progressing reaction. The value of the isotopic effect found
is near that found previously (Refs 1,2) for propane. The
data mentioned above all confirm (on the basis of ethane)
the abnormally high value of the isotopic effect in the
reaction of methane formation. The equality of the order of
magnitude of the isotopic effect (with respect to methane)
for 02H6 and 0 3H8 indicates the existence of similar ethanes
in the formation of CH4 in the two above-mentioned cases.
Correction note: The provisional experiments carried out by
the authors concerning the cracking of the ethane mixture
12 12 14 14
C H 3 - C H 3 and C H 3 -, C H3 showed that in this case the
Card 2/3 isotopic effect (with respect to methane) is considevably

lower than in the cracking of a R 3 C H 3' This confirms
the above assumption that the abnormally high value of the
isotopic effect in the cracking of ethane 012 H3 - C14H3 is
due to a quantum effect connected with the disturbance of
symmetry. There are I table and 7 references, 4 of which are

ABSTRACT: The effects mentioned in the title were investigated under
conditions of high temperature cracking by means of a mixture of
C12 11 3-C 12H3with C14H 3-C1411 3 *The re3ults i6re compared nith
the cracking of C14 H 3-C 12H3as described in reference 1.
This experiment was made for the reason that hydrocarbona with
only partly marked C-atoms yielded higher values for tb6
isotopic effect (Refs 1-3) than could be expected accor'ding to
the present theoretical opinions (Refs 4, 5). The following is
Card 1/3 given as a possible explanation of this.phenomenon:

hydrocarbon molecules exhibit a plane of symmetry vertical to
the chain or a corresponding alternating axis. The introduction
of a marked C-atom has a disturbing effect upon this symmetry,
and the transition from the symmetrical to th-a asymmetrical
molecule might entail a considerable kinetic effect. Herefrom
it -resulted that the symmetrical ethanes C 12 H C12H and
3- 3
C14H 3'C 14H3had to differ from asymmetrical
012 H3- C14113in their effect. The experimental data (Table 1)
shows that the kinetic isotopic effect amounts to 511% in
the formation of methane from C1411 3-0 14H 3 ; it is' therefore,
considerably lower than the value of 12;t2% of reference 1 found
for asymmetrical ethane. Measurements were made under entirely
equal conditions. This result shows that there is no direct
proportion between th!-a kinetic isotopic effect and the reduced
Card 2/3 mass, and confirms Ve assumption that the disturbance of the

TEXT: The authors report on their investigations of the kinetics of do-
hydrogenation of ethyl benzene at temperatures between 660 and 740 0C~
They discuss'data in publications (Refs. 2, 3), and explain contradictions
by the fact that at high temperatures the styrene yield depends on the re-
action period. To obtain a high stxrenjeyield it was necessary to guarantee
d short reaction period and a quickg steady heating. This was attained by
means of a pseudoliquid coke powder layer, Fig. 1,,shows the experimental
arrangement. Heating was performed by a gLjLhite%1spiral passed through by
current. The ethyl benzene gasified and mixed with CO or N was introduced

TITLE: On the Kinetic Rules of High-temperature Cracking of
Isopentane
PERIODICAL: Kinetika i kataliz, 1960, Vol. 1, No- 3, PP- 340 - 344
TEXT: The cracking of isopentane between 760 and 8400C was studied at
a pressure of 110 � 2 mm Hg. The reaction products were determined chroma-
tographically. The following was determined for the constant of the
cracking rate: 8-33 sec' 1 at 5400C, 26 see-1 at 7600C, and 95 sec- 1 at
8200C. The activation energy is 60-5 1 2 kcal/mole; the factor of the
-1
exponential function is 1014 see . At these temperatures, the cracking
of isopentane proceeds as a first-order reaction. The self-brakin&~:od_
the reaction known at low temperatures was not observed at the experi.-
mental temperatures. The following summary scheme was drawn up for the
decomposition mechanism: dehydrogenation of isopentane practically does

not occur; the probability of the cracking reaction proceeding under
formation of C 2 and C3 chains is much greeter than the probability of the
formation of butylenes. The formation of P-butylene can be explained by
the fact that during the cleavage of the C-C bond 3 or 4 hydrogen atom
is more easily cracked from the secondary C atom than the primary hydro-
gen atom. The probability of the formation of y-butylene is small in the
cracking of isopentane, that is, if the C-C bond I is cleft, the hydro-
gen atom is cracked from the tertiary C atom and isobutylene forms.
y-butylene should be formed according to the radical chain mechanism.
The relatively small amounts of y-butylene in the cracking products indi-
cate that the cracking reaction proceeds according to the mechanism of
the molecular reaction. There are 3 figures, 1 table and 7 references:

TEXT: The authors investigated the dehydrogenation of isopentane over
fixed and fluidized beds of chromium-oxide/aiuniinum--oxide catalysts. Three
catalyst.s with the following compositions were used: catalyst Wo. 1:
14.6% by weight Cr 2031 83-7% by weight Al 203 and 1-5% by weight K 20; cata-
lyst N Io. 2: 7% by weight Cr2037 92.5% by weight Al 203 and 0.5% by weight
K20; catalyst No. 3 was prepared by B. A. Kazanskiy (Ref. 3). The reaction
products were analyzed by gas chromatography. The authors studied the
kinetics of the dehydrogenation process in a fluidized bed under vacuum
at grain sizes of the catalyst varying between 0.05 and 0.01 mm. The
equilibrium constant of isopentane dehydrogenation is given in Table 1.

The equilibrium composition of the products at 760 and at 100 mm Hg is
shown in Figs. 1 and 2. The vacuum apparatus is represented in Fig. 3.
The catalyst.s exhibited practically equal activity~ Dehydrogenation at
55000 yielded 30-31~ isoamylenes and isoprene, with 46-47~ of the
0
isopentane entering into reaction, while at 520 C the yield was only
22-23% with 28% of the isopentane reacting. Table 2 shows the composition
of the products formed at dehydrogenation of isopentane on the fixed
catalyst. The kinetics of isopentane dehydrogenation on the fluidized and
fixed catalysts in the region of small yields (up to 30%) were studied
at 500, 520, and 5500C. Distribution curves of the reaction products appear
in Figs. 4 and 5. Special characteristics of the dehydrogenation reaction
of isopentane were discussed giving kinetic equations which allow for the
homogeneity of the catalyst surface. The kinetic curves for isopentane
dehydrogenation on the fixed and fluidized catalysts in the region of
small yields are represented in Fig. 6. The activation energy of dehydro-
genation is 44 kcal/mole. The dehydrogenation of isopentane at higher
temperatures and lower pressure is described in Table 4. At 600'C,
100 mm Fg and a sojourn time of 2.2 see, 62-3% of the isopentane reacts,

TITLEt A Method of Investigating the Mechanism of Fast Reactions in

ABSTRACT; The term turbulent reactor is applied by the authors to a
reactor vessel with an intense intermixing device. After
giving a survey of the methods of investigating the kinetics
of reactions and mentioning the isotopic method by M.B.Heyman,
the authors explain the simplification of kinetic equations
attained when using tagged atoms and by intensively inter-
mixing the reagents as a result of the falling away of con-
centration- and temperature gradients. The method makes it
possible to deal with both single processes in the reaction
and also with the total process, and may therefore be used for
the purpose of judging the correctness of the scheme upon
which the reaction is based. By the example of the cracking of

TEXT: The authors studied the reaction mentioned in the title on
chromium- and aluminum oxide catalysts in the temperature range between
500*and 6000C by making use of a pseudoliquid layer. Fig. I shows a
scheme of the vacuum apparatus used for the purpose. A pseudoliquid
layer formed on the passage of isopentane through the catalyst. The
C2 - C5 hydrocarbons were chromatographically separated in a column with
diisoamyl phthalate and acetonyl acetone by the method described in
Ref. 5. Besides experiments made with a pseudoliquid catalyst layer the
authors carried out experiments with a resting layer (Table 1). As can

be Been therefrom, the catalysts of different compositions had a similar
activity. Figs. 2 and 3 supply typical curves for the amounts of reaction
products developed. The molar ratios C, : C4 and C2 : C3 approach unity
in the gases. These hydrocarbons were apparently formed by isopentane
cracking. The drop in selectivity with rising temperature fairly fitted
the increase in isopentane consumption for cracking. The products
contained 2-methyl butene-2, 2-methyl butene-1, and 3-methyl butene-1
at.aratio of 100 ; 50 : 16 at 5000C; at 52000, this ratio was
100 : 54 : 18; at 5500C, i-1; was 100 - 55 - 16; at 5800c, it was
100 : 56 : 14. This ratio was little dependent on pressure and on the
conversion degree of isopentane, and diverged little from the ratio of
equilibrium. The ratio of isoprene to the sum of the isoamylenes fitted
the ratio of equilibrium. This is indicative of the high rates of the
processes of isomerization and dehydrogenation of isoamylenes on oxide
catalysts. For the interpretation of experimental results in the range of
conversion degrees up to 30% the authors made use of equations (1) for
the pseudoliquid layer, and (2) for the resting layer. Fig. 4 shows that
the points established in the experiment group along the straight lines

1 and 2i The inclination angle..of these straight lines to the axis t/p
is, independent of pressure, equal to constant K. In the derivation of
equations (1) and (2), the authors made use of the concepts put forward
in the papers of Refs. 10 and 11 dealing with the course of irreversible
reactions on a ho ogeneous surface. These equations apply to the case
where iBoamylenes and isoprene are strongly adsorbed on the surface with
equal adsorp- coefficients. Equation (1) characterizes the conditions
under which the gas is perfectly mixed. A lacking mixture was assumed
in the derivation of equation (2). The authors conclude from the results
obtained that the ratio of the adsorption coefficients of isoprene and
isoamylenes on the chromium catalyst did not exceed 2. They conclude
furthermore that the said coefficient of isoamylenes lies higher by two
orders of magnitude than that of isopentane. A comparison of experi-
mental results on a-pseudoliquid and on a resting layer proves that in
the-former case the gas was completely intermixed while there was no
mixing in the latter case. By reducing the mixing it is possible to
increase the isoprene yield. The authors thank Academician B. A.
Kazanskiy for his discussion. There are 4 figures, I table, and 11
