Abstract

Alumina monohydrate catalyst base in microspherical form, is prepared by reacting an aqueous solution of alkali metal carbonate and a water soluble aluminate, adjusting the pH to less than 7 with an acidic water soluble aluminium salt, such as the sulphate and then adjusting the pH to between 7.5 and 9.5 with the addition of a water soluble aluminate, followed by heating to 75-150 DEG F. to precipitate the monohydrate. The precipitate is thereafter spray dried, without washing, at a temperature of 150 to 325 DEG F. to form microspheres and subsequently washed free from contaminants. After drying the microspheres may be treated with active metal catalysts and thereafter extruded through 1/8 or 1/16 inch orifices. The alkali metal carbonate employed, preferably sodium or potassium, should have a concentration less than 1% and the aluminate solution should be of 80% concentration. The mol. ratio sodium carbonate/alumina should be from 0.05-1 to 1. According to Example 2 the formed microspheres were slurried in water and finely divided MoO2 and CoCO3 were successively added; the suspension was heated to 180 DEG F. before flash drying to form a catalyst stock which was extruded to form catalyst particles. Reference is made to hydrogen treating and desulphurizing gas oil.
