    摘要: A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are separated from the isoolefins and disproportionated with ethylene to form a propylene product, while the thus separated isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene product.

    摘要: A process for producing propylene and 1-butene is disclosed. The process comprises dimerizing ethylene in the presence of a dimerization catalyst to produce a dimerization mixture comprising 1-butene and 2-butenes. The dimerization mixture is distilled to produce a 1-butene stream containing 1-butene and ethylene, a 2-butenes stream, and a heavy stream. The 2-butenes stream is reacted with ethylene in the presence of a metathesis catalyst to produce a metathesis mixture comprising propylene, ethylene, and 2-butenes. Propylene is separated from the metathesis mixture.
