ABSTRACT:
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.
