A metals scavenging composition comprising a rare earth component and a layered magnesium silicate, such as sepiolite or attapulgite, is mixed with separate particles of a cracking catalyst and the mixture used to crack hydrocarbon feedstocks containing relatively high concentrations of vanadium and other contaminant metals. The use of the metals scavenger prolongs the life of the catalyst while maintaining (1) relatively high conversions and gasoline yields, and (2) relatively low hydrogen and coke makes.

Catalytic cracking using a metals scavenging composition

A crystalline, galliosilicate molecular sieve having the offretite structure comprises silicon, gallium, oxygen and substantially no aluminum. The molecular sieve is synthesized by crystallizing a hydrogel reaction mixture which is preferably formed by mixing a substantially alumina-free galliosilicate hydrogel containing an offretite selective templating or directing agent with a galliosilicate solution substantially free of alumina. The crystallized molecular sieve can be employed, after activation by removing the templating agent and reducing its alkali metal content, as a component of a catalyst which is suitable for use in a variety of chemical conversion processes, preferably hydrocarbon conversion processes.

A midbarrel hydrocracking catalyst for use in producing middle distillate products from hydrocarbon feedstocks via hydrocracking comprises at least one hydrogenation component, preferably one containing a metal selected from Group VIB and/or Group VIII of the Periodic Table of Elements, a layered magnesium silicate such as sepiolite, an intercalated clay such as pillared clay, and, optionally, a crystalline molecular sieve, preferably a zeolitic molecular sieve such as the modified Y zeolite known as LZ-10 zeolite.

A crystalline, gallioaluminosilicate molecular sieve having the offretite structure is synthesized by mixing a substantially gallia-free aluminosilicate hydrogel containing a templating or directing agent with a galliosilicate solultion substantially free of alumina to form a mixture and then crystallizing the resultant mixture, usually in 24 hours or less.
