Synthesis of MAZ/ZSM-5 composite zeolite and its catalytic performance in FCC gasoline aromatization

A novel one-pot procedure for the preparation of mazzite and ZSM-5 composite zeolite was developed. This synthesis procedure provided a convenient method for the in situ utilization of the silica source in the mazzite zeolite synthesis procedure. Mild dealumination of the composite created a secondary mesopore network. The catalytic evaluation results showed that the zinc loaded composite has a good performance in FCC gasoline aromatization reactions. (C) 2006 Elsevier B.V. All rights reserved.
