ABSTRACT:
Gallium-containing, crystalline silicate molecular sieves in which substantially all of the gallium occupies molecular sieve lattice positions or is intimately associated with the crystal lattice of the silicate sieve when composited into a silica matrix are shown to form catalyst compositions having superior properties for the catalytic, liquid-phase isomerization of a xylene-containing stream containing a minor amount of ethylbenzene to a product mixture rich in paraxylene.
