Abstract
A method for enhancing the activity of inorganic oxide materials is disclosed which involves treating same with a fluoride reagent of ammonium fluoride or boron fluoride, contacting the fluoride reagent contacted material with an ammonium exchange solution and then calcining the final product.
Claims9
A method for enhancing the activity of an inorganic oxide material, which comprises contacting said material with a fluoride reagent selected from the group consisting of ammonium fluoride and boron fluoride at a temperature of from about 0.degree. C. to about 100.degree. C., contacting said fluoride reagent contacted material with an aqueous ammonium exchange solution and thereafter calcining said material at a temperature of from about 200.degree. C. to about 600.degree. C. in order to obtain an inorganic oxide material having enhanced activity.
