Conversion of synthesis gas to ethane

摘要

Synthesis gas is converted to an exclusively hydrocarbon product with selectivity to ethane by the use of a catalyst which comprises a zeolite and a metal component distributed within the pore structure of the zeolite. The preferred zeolites have a Constraint Index of 1 to 12 and a silica:alumina ratio of at least 12:1 and of these ZSM-5 is preferred. The metal component which may be introduced into the zeolite by impregnation from liquid ammonia solutions, is preferably chromium, zinc and aluminum, optionally with potassium.
