SOURCE: Zh. ekaper. i teore fizo, ve 47, no, 1, 1964, 382-383

nuclear resonance, corundum, vanadium impurity
ABSTRACT: Electron-nuclear paramagnetic resonance has been
,experimentally displayed in corundurs doped with V3+. The measure-
ments were performed by means of a nuclear resonance spectrometer
with elevated sensitivity,-which made it possible to obtain on tho
.,aluminum nuclei a signal-to-noise ratio of the order of*several
!;thousands at helium temperatures. Measurements involved the use of
an improved Pound's diagram in the spectrometer an~ the mithod of
synchronous detection. The corundum specimen investigated had a
volume of 0.1 CM3 and a concentration of V3+ ions of.approximately
0.5% in relation to the number of Al,,3+ tons. When the crystal wai;

oriented so that the angle 0 between its trigonal axis and external
magnetic field H lay within a range from 20* to 45', a clear resonance
line, corresponding to transition :LI/2, is observed at a temperature
of 1.5K. The width of the line is 0.2-0.3 Mc. By increasing the
temperature to 4.2K the line broadens and the effect disappears. At
angles less than 20* or greater*than 45* the effect cannot be ob-
iserved because the line is too broad. In the first case (100 m) the equations of tidal
wave movement in the following form:

ABSTRACT: Various schemes for the gasification of Siberian brown
coals mined by open-cast methods (high pressure, fluidised
bed and. blast furnace p-roces(;) with simultaneous utilisation
of some of the gas components for synthesis, for the purpose
of a centralised supply of gas for the Eastern regions of the
USSR, are discussed and an experimental investigation of semi-
coking of ITATSK coals and gasification of semi-coke under
pressure up to 30 atm. is described. Data on the ITATSK brown
coals are given in Table 1, mean data on the yield and quality
of semi-coke and the composition of gas in Tables 2 and 3,
respectively. Semi-coking wits carried out using a stream of
nitrogen-steam mixture (50% 112, 50% H20). The method and
apparatus used were described in Ref.2. Gasification of semi-

ABSTRACT: Gasification under pressure makes it possible to obtain
cheap, fine-grained, 'low-quality fuels- The authors
investigated a gas generating process under high pressure
to ebtain a,gas.with required proportion of active com-
ponents and the minimum content of methane, The plant
used for these experiments is described (Fig.1). The
basic apparatus comprises a cylinder made of stainless
steel (height = 900 min, internal diameter = 150 mm),;
Inside the cylinder Is a stainless steel reactor (length
500 min and internal diameter = 50 min) on which a *,l 1,,v
heater is fixed. Toachieve better mixing of the reaction
gases (02, OH4, 002),ifith the water vapour at the inlet
of the reactor tube, a perforated 100 min high cylinder
is used which is fillod with 8 - 10 min pieces of fireclay.

content in the gas is considerably lower when the helpi'lL

reactions. Fig.4: the dependence of the methane content
in dry gas on the temperature at varying ratios of
00026H 0 and pressures of 1 and 20 atms. An increase In
the CK:H2O ratio leads to a decreased content of' methane
In the gas and increases In the pressure to an increassd
riethane content. The sameapplies to increases in tempera-
ture; in this case the increase is greater the hi&ier the
pressure and the lower the 002:H20 ratio. These experl-
raents show that the most effective method of in1hibiting
the formation of methane during the gasification of fuels
tinder pressure lies in changing the composition of the gas
mixture entering the zone of reduction reactions. 1~irther
