Abstract
Globular particles containing alumina, which may be used as catalysts, are obtained by mixing an aluminium oxide hydrosol with a finely ground solid additive in an amount of 30 to 90% by weight with reference to total dry substance and with hexamethylene tetramine or urea, dripping the mixture into a liquid immiscible with water at elevated temperature, separating the resultant particles after gelation and drying and calcining them. In examples the solid additives mixed with the aluminium oxide hydrosols are aluminium hydroxide, silica gel, titanium dioxide, kaolin and ground quartz, the base is urotropine (hexamethylene tetramine), and the mixture is dripped into heated paraffin oil; in one example aluminium hydroxide and cobaltous hydroxide are added to the hydrosol, and after calcination the globules are soaked in a solution of molybdic acid and calcined. A list of other solid additives is given. The aluminium hydroxide hydrosols are prepared by dissolving aluminium chips in aluminium chloride solution and in aluminium nitrate solution.
