USE OF ZEOLITE ITQ-21 IN THE CATALYTIC CRACKING OF ORGANIC COMPOUNDS

摘要

The invention relates to the use of zeolite ITQ-21 in the catalytic cracking of organic compounds. In said cracking process, the zeolite ITQ-21 can be present in the catalyst as the sole zeolite component of same or combined wi th at least one second zeolite component. Moreover, said zeolite ITQ-21 can be present in the catalyst as unmodified zeolite ITQ-21 or as modified zeolite ITQ-21. The preferred combinations, in which the zeolite forms part of the cracking catalyst, are those in which it is combined with at least one secon d zeolite component. The preferred modifications comprise, for example, a modification by means of post-synthesis treatment with phosphorus or a modification involving the introduction of acid centres. The catalytic proce ss is preferably an FCC- or DCC-type hydrocarbon cracking process.
