Abstract
A process for the double bond isomerization of olefinic feed compounds is provided comprising contacting the olefinic feed compounds and a catalyst under reaction conditions sufficient to produce double bond isomerization, wherein the catalyst is an aluminophosphate-containing molecular sieve with pores having a diameter in the range of about 3.8 Å to about 5 Å. The process provides high conversion of normal alpha-olefins and high selectivity for linear internal olefins.
Claims15
A process for the double bond isomerization of normal alpha olefins having from 4 to 50 carbon atoms, the process which comprises contacting the normal alpha olefins with a catalyst under reaction conditions sufficient to produce double bond isomerization, wherein the catalyst comprises an aluminophosphate-containing molecular sieve with one-dimensional pores having a diameter in the range of from about 3.8 Å to about 5.0 Å and wherein said catalyst at a conversion rate of 60% will give a yield of branched olefins of less than 3.5 weight % with a feed of 1-pentene.
