Abstract
AbstractLight olefins and para‐xylene were produced with high selectivity in the reaction of toluene with methanol over a modified HZSM‐5 catalyst. Ordered mesoporous structure and weaker acidic sites led to significant contribution to the selectivity toward para‐xylene. By means of a single‐pulse reaction and the temperature‐programmed surface reaction, it was confirmed that the presence of toluene and as‐produced xylene shortened the reaction induction period and reduced the formation temperature of ethylene and propylene, which was beneficial to improve the selectivity toward light olefins, particularly ethylene.
