Patent ID: 8431760

Claim:
A hydrocarbon-conversion process selected from isomerization, reforming, dehydrocyclization, dehydrogenation, disproportionation, transalkylation, dealkylation, polymerization, hydrocracking, and catalytic cracking, which comprises contacting a hydrocarbon feedstock in a conversion zone, at hydrocarbon-conversion conditions for isomerization, reforming, dehydrocyclization, dehydrogenation, disproportionation, transalkylation, dealkylation, polymerization, hydrocracking, and catalytic cracking, with a catalyst comprising a MgMxAPSO molecular sieve wherein Mg and Mx represent elements in the crystalline framework structure, Mg represents magnesium and Mx represents one or more of the group consisting of manganese, cobalt, nickel, iron and zinc, and wherein the molar proportion of each of Mg and Mx in the crystalline framework structure on an anhydrous basis is from about 0.002 to about 0.01 mol fraction, the sieve having a mean crystallite diameter of less than about 2.5 microns and a mean crystallite length of less than about 4 microns, to obtain a converted product, optionally a platinum-group metal component and optionally an inorganic-oxide matrix.
