ABSTRACT:
The invention relates to a process for the preparation of a high-purity, thermally stable catalyst carrier based on aluminosilicate with 0.5 to 50% by weight SiO.sub.2 by mixing an aluminum compound with a silicic acid compound in an aqueous medium, and subsequently drying or calcining the product obtained. The aluminum component used is a C.sub.2 to C.sub.20+ aluminum alkoxide hydrolyzed with water and purified by means of ion exchangers. Simultaneously or subsequently orthosilicic acid purified by means of ion exchangers is added to the aluminum compound.
