Method of preparing composite catalyst and hydrocarbon conversion therewith
Abstract
Abstract COMPOSITE CATALYST MADE BY ADMIXING WITH AN AQUEOUS ALKALI METAL SILICATE A PARTICULATE WEIGHTING AGENT SUCH AS CLAY, DESIRABLY DISPERSED IN WATER, SO AS TO COAT THE CLAY WITH ALKALI METAL SILICATE, AGEING AT A PH OF FROM ABOUT 8 TO 10, OPTIONALLY ADDING A SOURCE OF ZIRCONIA OR ALUMINA AND ZIRCONIA, REDUCING THE PH TO ABOUT 4.0 TO 7.0 TO FORM A SILICEOUS GEL-WEIGHING AGENT-MATRIX SLURRY, ADMIXING THEREWITH A SLURRY OF RARE EARTH CRYSTALLINE ALUMINOSILICATE, DRYING IN THE FORM OF PARTICLES SUITABLE FOR FLUID CATALYTIC CONVERSION, EXCHANGING WITH AMMONIUM IONS TO REDUCE ALKALI METAL CONTENT; AND POST EXCHANGING WITH RARE EARTH IONS OR ALUMINUM IONS TO SUBSTANTIALLY REPLACE AMMONIUM IONS AND TO REMOVE RESIDUAL ALKALI METAL IONS.
