Abstract
A feedstream comprising hydrogen and a gas selected from carbon monoxide, carbon dioxide, or a combination thereof is converted to a product mixture containing a combination of saturated and unsaturated two carbon atom and three carbon atom hydrocarbons via contact with a mixed catalyst comprising a mixed metal oxide catalyst selected from a copper oxide, copper oxide/zinc oxide, copper oxide/alumina, copper oxide/zinc oxide/alumina catalyst, a zinc oxide/chromium oxide catalyst, or a combination thereof, in admixture with a molecular sieve catalyst having a CHA, AEI, AEL, AFI, BEA, or DDR framework type, or a combination of such molecular sieves. Exemplary molecular sieve catalysts include SAPO-34, SAPO-18, SAPO-5, and Beta. Advantages include reduced production of C1 hydrocarbons, C4 and higher hydrocarbons, or both; long catalyst lifetimes; desirable conversions; and desirable proportions of C2 and C3 paraffins.
