Olefin oligomerization process

摘要

In a process for oligomerizing an olefinic hydrocarbon feedstock comprising at least 65 wt% olefins, the feedstock is contacted under oligomerization conditions with (a) a first unidimensional 10-ring molecular sieve catalyst and (b) a second multidimensional crystalline molecular sieve catalyst. The first and second catalysts may be contained in separate reactors or as separate beds in a single reactor.
