Dynamic modification of H+ active site on HZSM-5 catalyst

Dynamic modification of H+ active sites from molecular hydrogen on Zn loaded HZSM-5 was studied by IR spectroscopy of adsorbed pyridine. By heating in the presence of molecular hydrogen, H+ active sites were formed with a concomitant decline of Lewis acid sites. The Lewis acid sites began to convert...
