"CATALYTIC COMPOSITE COMPRISING AN AMORPHOUS SOLID SOLUTION OF PHOSPHORUS, SILICON AND ALUMINUM OXIDES" ABSTRACT A catalytic composite which is an amorphous solid solution of phosphorus, silicon and aluminum oxides is disclosed. The composite is characterized in thatit contains from 5 to 50 weight percent A12O3, from 10 to 90 weight percent SiO2and from 5 to 40 weight percent P2O5 and has pores whose average diameters range from 30 to 200 Angstroms. The composite is further characterized in that it has a pore volume of 0.35 to 0.75 cc/g and a surface area of about 200 to about 420 m2/g. The composite may be prepared by forming a mixture of sols of alu- mina and silica and a phosphorus compound, gelling the mixture to form particlesand then calcining the particles to provide the amorphous solid solution. The amorphous composite may be used as a catalyst either as is or with additional catalytic metals selected from the metals of Group VIB and VIII of the Periodic Table and mixtures thereof) dispersed thereon to catalyze various hydrocarbon conversion processes such as hydrocracking and alkylation.
