Patent GB-796756-A (GB)
Title: Process for preparing silica-alumina catalyst
IPC: C10G11/04
Filed: 1956-06-27
Abstract: A silica-alumina gel catalyst is prepared by reacting an aqueous alkali metal silicate solution with carbon dioxide in amount sufficient to form a silica hydrogel containing dissolved alkali metal carbonate, commingling with the hydrogel an aqueous solution of an aluminium salt of a strong mineral acid whereby alumina is precipitated in and on the hydrogel, and washing and drying the resulting composition.  In a preferred procedure, sodium silicate solution is used and the mixture is maintained as a slurry by agitation during the formation of the silica hydrogel and during a 10 minute to 1 hour ageing step; an aqueous solution of aluminium sulphate is added with continued agitation, the resulting slurry being aged for up to 1/2 hour and then filtered, dried, washed free from soda and sulphate ions, and redried.  Carbon dioxide may be bubbled into the silicate solution or may be contacted therewith in a mixing nozzle.  The carbon dioxide may be insufficient for complete neutralization of the silicate, or may be used in excess; in the latter case, however, a basic aluminium sulphate is formed from which it is difficult to remove sulphate ions.  Catalysts containing up to 30 per cent alumina may be prepared using sodium silicates having varying SiO2 : Na2O ratios; for higher alumina contents, ammonia may be used to supplement the neutralizing action of the sodium carbonate.  Aluminium nitrate or chloride may be used in place of the sulphate.  The final catalyst may be in the form of pellets, granules, or microspheres prepared by spray-drying, and may be used for cracking hydrocarbons at 454-510 DEG  C. and at atmospheric pressure.
