摘要
ZSM-5 nanocrystals with a short b-axis length exhibited higher activity and lower coke selectivity in a methanol-to-aromatics reaction, compared to microcrystals, whether in the pristine state or in molded particles with an average size of 100 microns by adding silica-sol and kaolin clay required by industrial scale application.
