International Classification:

C07C 402

US Classification:

585648, 585652, 208230

Assignee:

Equistar Chemicals, LP - Houston TX

International Classification:

C07C006/04

US Classification:

585324, 585331, 585332, 585643, 585646, 585664, 585671

Abstract:

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.
