ABSTRACT:
In a process for oligomerizing an olefinic hydrocarbon feedstock comprising sulfur-containing molecules, the feedstock is contacted in the absence of hydrogen with a first metal oxide catalyst at a temperature in excess of 150° C. and then is contacted under olefin oligomerization conditions with a second catalyst comprising a crystalline molecular sieve, such as ZSM-22 or ZSM-57.
