Abstract
Processes for the conversion, under conditions and with a catalyst system effective for olefin metathesis, of hydrocarbon feedstocks comprising butylene, for example all or a large proportion of a single C4 olefin isomer such as butene-1, are described. Olefin products, and particularly propylene, are formed in the presence of a catalyst comprising a solid support and a tungsten hydride bonded to alumina present in the support. This occurs despite the expectation that the olefin metathesis reaction mechanism leads to the formation of olefin products having other carbon numbers.
