摘要:
Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst.
