Abstract:
A fluidizable cracking catalyst comprising a matrix, from about 5 to about 50 weight percent of a crystalline, zeolitic aluminosilicate and from about 2 to about 80 weight percent of a modified alumina having a pore size distribution, determined after calcining said alumina at 788.degree. C. for 3 hours, and with reference to a nitrogen desorption curve, such as to give an average pore diameter in the range of from about 2 to about 14 nm, with at least about 60 percent of the total pore volume being in pores having a diameter in the range of from about 2 to about 20 nm, said pore size distribution having been determined on the alumina independent of the remaining catalyst components.
