ABSTRACT:
A process for producing active aluminum oxide granulate of high porosity which comprises mixing finely ground aluminum oxide powder with at least one finely ground additive selected from the group consisting of water-soluble salts and non-ionic substances which do not react with aluminum oxide, are not hygroscopic at room temperature and below about 60% relative humidity and do not undergo any phase transformation at temperatures of up to about 100.degree. C. in a ratio by weight of aluminum oxide to additive of from about 90:10 to 30:70, granulating the mixture in the presence of water, ageing the granulate for at least 5 hours at 50.degree. to 100.degree. C., washing out water-soluble additive, drying and activating the granulate at a temperature of from 200.degree. to 500.degree. C.
