Abstract
A hydrocarbon conversion catalyst containing 20-60 per cent by weight of alumina and 80-40 per cent by weight of silica is prepared by mechanically mixing a silica hydrogel having a silica content of 3-20 per cent by weight with an alumina hydrosol containing 1-5 per cent by weight of alumina, continuing the mixing at least until the silica hydrogel reverts to a hydrosol (aqueous ammonia may be added to aid this reversion), drying the resulting mixture at a temperature of about 250 DEG F.-500 DEG F., followed by activation at at least 1,000 DEG F. The alumina hydrosol is prepared by treating amalgamated aluminium with dilute acetic acid or formic acid, or from the aluminium alcoholate of a preferably water insoluble alcohol whilst the silica hydrogel may be prepared by treating sodium silicate solution with a mineral acid and is washed substantially free of alkali metal.
