A process for converting a feedstock comprising organic compounds to conversion product which comprises contacting said feedstock at organic compound conversion conditions with a catalyst comprising an active form of a synthetic porous crystalline material, said synthetic porous crystalline material

A process for converting a feedstock comprising organic compounds to conversion product which comprises contacting said feedstock at organic compound conversion conditions with a catalyst comprising an active form of a synthetic porous crystalline material, said synthetic porous crystalline material having been manufactured by the method comprising: (i) forming a reaction mixture hydrogel having a pH of from about 10 to about 14, containing sources of alkali or alkaline earth metal (M) cations; an oxide of trivalent element (X); an oxide of tetravalent element (Y); n-propylamine directing agent (R); and water, said reaction mixture having a composition in terms of mole ratios, within the following ranges: ________________________________ - YO2/X2O3 2O/YO2 10 to 35 OH-/YO2 0.1 to 0.3 M/YO2 0.2 to 0.6 R/YO2 0.01 to 0.6 ________________________________ (ii) maintaining the reaction mixture until crystals of ZSM-5 structure are formed, (iii) recovering the ZSM-5 crystals from the reaction mixture, (iv) ammonium exchanging the recovered ZSM-5 crystals, (v) deagglomerating the ion-exchanged crystals, (vi) slurrying a matrix material with the deagglomerated ZSM-5 crystals at a pH of from about 2 to about 12, to yield a ZSM-5/matrix material comprising from about 5 to about 80 wt. % ZSM-5 and from about 20 to about 95 wt. % matrix, (vii) drying the ZSM-5/matrix material, and (viii) converting the dried ZSM-5/matrix material to the protonic form having an Alpha Value of greater than about 30.
