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 with 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 second 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 process is preferably an FCC- or DCC-type hydrocarbon cracking process.
