The hydrogen production from tetralin was carried out under microwave heating compared with conventional heating. Pt-supported activated carbon was used as a catalyst and microwave receptor in the reaction. Microwave heating increased the conversion of tetralin dehydrogenation as compared with conventional heating up to 19% at the same condition (207 degrees C). Moreover, the microwave reaction exhibited the lower retardation constant resulting from naphthalene adsorption on the surface of heterogeneous catalyst. (C) 2010 Professor T. Nejat Veziroglu.
