    摘要: A novel particulate material for promoting combustion of carbon monoxide to carbon dioxide in the regeneration zone of a cyclic fluid cracking process without substantially affecting the ability of separate fluid cracking catalyst particles containing an active crystalline zeolitic aluminosilicate component to catalyze the hydrocarbon conversion reaction in the conversion zone. The novel promoter particles comprise coherent, catalytically inert microspheres of calcined kaolin clay having a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of about 2/1, a surface area (B.E.T.) in the range of about 10 to 15 m.sup.2 /g., a pore volume (as determined by nitrogen absorption) in the range of about 0.02 to 0.04 cc./gm., the calcined microspheres being impregnated with a trace amount of a platinum compound and being free from a component capable of cracking hydrocarbons in the absence of added hydrogen.

    摘要: A method for increasing the zeolite content of high zeolite content clay derived microspheres obtained by reacting porous precursor microspheres with a sodium silicate solution in the presence of seeds to crystallize zeolite Y in situ in macropores of precursor microspheres composed of a mixture of metakaolin and kaolin calcined to undergo the exotherm. The increased zeolite content is achieved by increasing macroporosity of the precursor microspheres and increasing the content of metakaolin in the precursor microspheres. The increase in zeolite is associated with an increase in catalytic activity and unexpectedly improved selectivity.
