Enhancing n-alkane dehydrogenation: Heating HZSM-5 zeolites in the absence of water leads to the dehydroxylation of Brønsted-acid sites and the formation of new (nonacidic) sites that are very selective for propane dehydrogenation. The new sites formed catalyze the dehydrogenation of propane at rates comparable to the rates shown by HZSM-5 prior to thermal treatment.
