Abstract
Limiting the sulphur level in olefin feedstocks to zeolite-catalysed oligomerization enhances selectivity to trimmer and catalyst life and activity.
Claims2
A process for the oligomerization of an olefinic feedstock which comprises contacting under oligomerization conditions an olefinic feedstock containing from 0.1 to 2 ppm by volume of sulphur-containing compounds having a desorption temperature above 170° C. with a catalyst comprising a crystalline molecular sieve and recovering a product containing at least one olefin oligomer, said process further characterized by a step of reducing the content of said sulphur-containing compounds in said feedstock prior to said contacting.
