Abstract

Abstract CATALYST MATRIX MATERIAL FOR CARRY ACTIVE CATALYTIC COMPONENT. MATRIX MADE UP OF (1) 20 TO 95 WT. PERCENT POROUS SILICA GEL OR SILICA-ZIRCONIA GEL, THE GEL HAVING PORE VOLUME OF AT LEAST ABOUT 0.6 CC. PER GRAM AND (2) 5 TO 80 WT. PERCENT OF WEIGHTING AGENT, SUCH AS CLAY. METHOD OF PREPARING SUCH MATRIX. ALSO DISCLOSES A COMPOSITE CATALYST MADE UP OF CRYSTALLINE ALUMINOSILICATE PARTICLES CONTAINED IN SUCH MATRIX, THE OVERALL COMPOSITE HAVING A PACKED DENSITY OF AT LEAST 0.3 GRAM/CC. COMPOSITE 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 ZIRCONIUM SALT, DESIRABLY AS AN AQUEOUS SOLUTION, REDUCING THE PH TO ABOUT 4.0 TO 7.0 TO FORM A SILICA GEL-WEIGHTING AGENT OR A SILICA GEL-ZIRCONIA GEL-WEIGHTING AGENT MATRIX SLURRY, ADMIXING A SLURRY OF CRYSTALLINE ALUMINOSILICATE, AND DRYING IN THE FORM OF PARTICLES SUITABLE FOR FLUID CATALYTIC CONVERSION.
