Abstract
Small- and large-port mordenite zeolites have been characterized by 27Al m.a.s.n.m.r. and infrared spectroscopy to evaluate the observed changes in catalytic properties as a function of the dealumination degree. As a test reaction, n-hexane cracking was used. A dual Lewis–Brønsted cracking mechanism, together with a specific structural change upon dealumination, is proposed to be responsible for the high activity of some of these H-mordenites.
