ABSTRACT:
Novel heterogeneous, nickel-containing catalysts comprising
A. a nickel carbonyl complex, and
B. an acidic, solid, silica-based material are active in numerous reactive environments such as oligomerization, including homo- and co-dimerization, and polymerization of various olefins. In specific aspects, bis(triphenylphosphine) nickel dicarbonyl supported on an acidic, calcined, silica-alumina support containing a separate alumina phase, is active in, for instance, the oligomerization, particularly dimerization, of ethylene and propylene, the codimerization of a conjugated diene and an alpha-olefin and the polymerization of conjugated dienes.
