Abstract

Titania-alumina-silica hydrosols are prepared by reacting titanium and aluminum salts with an alkaline metal silicate solution at a pH of about 3. The hydrosol compositions may be dried to form inorganic-titania-alumina-silica gels or the hydrosols may be used as inorganic binders for the preparation of catalyst compositions which may contain clay and zeolites.
