ABSTRACT:

DEGUSSA AG, Imhausen Chemie GmbH, Ruhrkohle Oel und Gas GmbH and, on their behalf, the Engler Bunte Institute of the University of Karlsruhe have developed zeolite catalysts for the production of hydrocarbons from methanol or synthetic gas, which corresponds to the crude gas of coal gasification, the technical basis of the process have been worked out and process concepts have been produced. Many combination catalysts for the direct conversion of synthetic gas to hydrocarbons were produced from Fischer-Tropsch (FT) components and zeolite and were tested. Finally, attractive results were achieved with catalysts which consist of an alkalized iron FT component, HZSM5 and an aluminium oxide binder. The synthetic gas conversion on combination contacts was examined in detail.  It was possible to use gases rich in CO (H sub 2 /CO approx.= 0.6) directly, because a quick reaction occurs in the system from H sub 2 O with CO. It was possible to find catalysts and conditions with a favourable life of both catalyst components (a number of days). Above all, success was obtained in repeatedly regenerating the combination contacts without an appreciable loss of activity and selectivity. (orig./EF). (Copyright (c) 1990 by FIZ.
