Abstract
A process for the catalyzed oligomerization of ethylene to a product rich in linear C.sub.4 olefins using a catalyst composition made by incorporating a major amount of HAMS-1B crystalline borosilicate molecular sieve composited in an inorganic matrix or an amorphous, silica-alumina support with minor amounts of a nickel compound and a zinc compound and calcining the result to form a composite containing supported zinc and nickel oxides.
Claims10
A process for the oligomerization of ethylene to a product rich in linear butenes comprising contacting ethylene under oligomerization conditions with a catalyst composition comprising a minor amount of nickel as the oxide and a minor amount of zinc as the oxide both incorporated in a major amount of a support consistihg of (1) a HAMS-1B crystalline borosilicate molecular sieve composited in an inorganic matrix, or (2) an amorphous silica-alumina.
