Process for selectively converting ethene to isobutylene over selectivated ZSM-35 |
摘要 |
The present invention relates to a process for the oligomerization of ethene to a product rich in isobutylene comprising contacting a feedstock comprising ethene under oligomerization conditions with a catalyst composition comprising a porous crystalline silicate having the structure of ZSM-35 zeolite whose surface has been at least partially deactivated for acid catalyzed reactions by a) coking or b) chemisorption of a surface-deactivating agent, e.g., collidine, which possesses an average cross section diameter greater than that of the zeolite pores.
