Process for selectively converting linear paraffins to linear alpha olefins

摘要

This invention relates to a two step process for converting linear paraffins to alpha olefins. The first step comprises contacting said paraffins with a catalyst comprising an oxide an alkali or alkaline earth metal optionally dispersed on a refractory and porous carrier. The product of this process contains only small amounts of aromatics and branched olefins. The cracked product is then converted to an olefin product containing primarily alph olefins by contacting with ethylene and a disproportionation catalyst as disproportionation conditions.
