Patent

CA 2477700

A catalytic cracking process for selectively producing C2 to C4 olefins is described in which a feedstock containing hydrocarbons having at least 5 carbon atoms is contacted, under catalytic cracking conditions, with a catalyst composition comprising the synthetic porous crystalline material ITQ- 13 and, optionally, a large pore molecular sieve, such as zeolite Y.

L'invention concerne un procédé de craquage catalytique permettant de produire sélectivement des oléfines C¿2?-C¿4?. Dans ce procédé, une charge d'alimentation qui contient des hydrocarbures comprenant au moins 5 atomes de carbone est mise en contact, dans des conditions de craquage catalytique, avec une composition catalytique comprenant un matériau cristallin poreux synthétique ITQ-13 et, éventuellement, un tamis moléculaire à grands pores, tel que le zéolite Y.
