Abstract
Oligomerization degree of olefins may be controlled by employing mixed molecular sieve catalysts. Propene may be trimerized to nonene using ZSM-5 and ZSM-22, especially in an extrudate admixture.
Claims15
A process for the oligomerization of an olefin comprising contacting under oligomerization conditions a feed comprising at least one olefin with a catalyst comprising at least one zeolite having a refined constraint index (CI.degree.) greater than 10 and at least one zeolite having a CI.degree. within the range of from 2 to 10, and recovering a product comprising at least one olefin oligomer, said zeolites being present in a proportion within the range of 10:90 to 90:10 by weight.
