Ultrastable Y containing framework gallium

摘要

The invention relates to framework gallium containing ultrastable Y having a framework (silica:alumina+gallium oxide) SiO.sub.2 /(Al.sub.2 O. sub.3 +Ga.sub.2 O.sub.3) mole ratio of 18:1 which contains at least 2.2% framework gallium. Moreover, the invention includes use of the framework gallium containing ultrastable Y in hydrocarbon conversion processes, such as reforming, catalytic cracking and aromatization.
