Alkali Metal and Alkaline Earth Metal. Alkali metal and alkaline earth metal which are supported on [gamma]-[Al.sub.2][O.sub.3] can modulate the distribution of the amount of alkali and base intensity, and they played slightly different roles: the alkali metal can modulate the amount of alkali apparently, while the alkaline earth metal can modulate the distribution of base intensity apparently.
