Abstract:

A hydrocarbon conversion catalyst composition, useful for paraffin-olefin alkylation, can comprise a three dimensional crystalline zeolite molecular sieve having a pore size large enough to adsorb 2,2,3-trimethylpentane and having a composition expressed in terms of mole ratios of oxides as a(I. sub. 2 O):b(IIO):c(III. sub. 2/3 O):d(IV. sub. 1/2 O)Al. sub. 2 O. sub. 3 :eSiO. sub. 2 wherein I represents a monovalent metal cation; II represents a divalent metal cation; III represents a trivalent metal cation; IV represents a tetravalent cation; a has a value of from zero to 0. 15; b has a value of from zero to 0. 75; c and d each have values of from zero to 1; e has a value of from 2 to 20; with the proviso that when e has a value of from 2 to 3, the value of ((b+c)=0. 75 to 1 and d=0; and with the proviso that when e has a value of > 3 to 4, the value of (b+c+d)=0. 6 to 1. 0; and with the further proviso that when e has a value of > 4 to 20, the value of (b+c+d)=0. 25 to 1.
