Layered oligomerization catalyst system

摘要

A process is disclosed for the oligomerization of light olefins to higher olefins. The process uses a catalyst that has an inert core and a thin layer of molecular sieve applied to the inert core. The molecular sieve is a crystalline silicoaluminate or metalloaluminophosphate and provides the acid sites for the oligomerization reactions. The thin layer provides for more selective control and limits the amount of oligomerization for liquid phase oligomerization processes.
