. "A less desirable reaction which also occurs duringreforming is the hydrocracking of paraffins, naphthenes and dealkylation of alkylaromatics to gaseous hydrocarbons such as methane and ethane.The above reforming reactions have previously been catalyzed by acidic catalysts comprising porous supports, such as alumina, which possess dehydrogenation promoting metal components impregnated or admixed th" . . .
