PROCESS FOR PRODUCING AROMATIC HYDROCARBONS USABLE AS GASOLINE CONSTITUENTS AND/OR UNSATURATED HYDROCARBONS SELECTED FROM ETHYLENE,PROPENE & BUTE NES

摘要

Aromatic and/or unsaturated hydrocarbons are produced by generating synthesis gas, synthesising an alcohol mature and subjecting at least one synthesis product to an alcohol conversion catalyst such as a zeolite of the Z5M-5 family. The synthesis catalyst contains the oxides of chromium, zinc and of at least one other metal having a divalent oxide more strongly basic than zinc oxide, for example of manganese.
