ALIPHATIC-AROMATIC HYDROCARBON INTERCONVERSION OVER ZN AND GA MODIFIED ZEOLITES: EFFECT OF ZEOLITE CRYSTALLINITY AND METHOD USED FOR MODIFICATION ON PERFORMANCE

摘要

Zeolites modified by the incorporation of either zinc or gallium display catalytic performances in the conversion of light alkanes to aromatics which are dependent on the crystallinity of the zeolite and the method used for the zinc or gallum incorporation. This work describes for the first time a comparative study of preparation variables and draws conclusions that are likely to be of general applicability to the design and use of such zeolite-based systems in aliphatic-aromatic hydrocarbon interconversion processes.
