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.

Un proceso se divulga para el oligomerization de olefins ligeros a olefins más altos. El proceso utiliza un catalizador que tenga una base inerte y una capa delgada del tamiz molecular aplicadas a la base inerte. El tamiz molecular es un silicoaluminate o un metalloaluminophosphate cristalino y proporciona los sitios ácidos para las reacciones del oligomerization. La capa delgada preve un control más selectivo y limita la cantidad de oligomerization para los procesos líquidos del oligomerization de la fase.
