1. Among the 1954 projects carried out by the Research and Development
Department of VEB Synthesewerk Schwarzheide, was a project on "Experiments
for the Further Develop#ent of Iron Contacts for Hydrocarbon Synthesis
according to Fischer-Tropseh". Its short designation was "Catalyst Research".
Its plan number was 013509b(F-401), It was under the supervision of Dipl.
Chem. Vinke (fnu)/
2. The following information on the project was given in to 1954 research and
development report of the Schwarzheide enterprise:
a. The investigation of the contacts was started with experiments aiming
at determining the core hardness (Kernhaerte), the frame volume
(Geruestvolumen), pore volume, the intermediary volume (Zwischearaum-
volumen), and the porosity. These expe*iments and the values obtained
did not show any reasonable relationship to the contact performance, the
activity and the selectivity, and were therefore abandoned.

that this time is sufficient and that the contacts are not damaged by
the temperature mentioned. An apparatus for the purifi oAtew-of the

Co The apparent and the true density were determined aeeerding to the
principle of high-pressure pyknometry, withthe aid of Xylol and, for
comparison purposes, with toluol and mercury. An apparatus for this
purpose was built; it permitted measurements with an error of plus or
minus 0.5%,
up to 10-4 mm. Hg, It was found through preliminary experiments

d. A series of experiments was carried out with an 110 contact *$
as a carrier and with an 110 contact without carrier. The
of contacts were always sbtained under t e same. conditions bud at differe*

e. A number of X-ray pictures was taken of contacts. The evaluation of these
pictures showed that Fe 0dd is generated at low temperatures; that Fe 0dd
and metallic iron are g;ndrated at medium temperatures; and furtherm;re
that metallic iron only is generated during the reduction at higher
temperatures.
