Dual component cracking catalyst with vanadium passivation and improved sulfur tolerance
This patent describes a dual component catalyst composition for the catalytic cracking of metal-containing hydrocarbonaceous feedstock. It comprises: a first component comprising an active cracking catalyst; and a second component, as a separate and distinct entity. The second component comprises: a calcium and magnesium containing material selected from the group consisting of dolomite, substantially amorphous calcium magnesium silicate, calcium magnesium oxide, calcium magnesium acetate, calcium magnesium carbonate, and calcium magnesium subcarbonate; a magnesium containing material comprising a hydrous magnesium silicate, and a binder selected from the group consisting of kaolin, bentonite, montmorillonite, saponite, hectorite, alumina, silica, titania, zirconia, silica-alumina, and combinations thereof.
