ABSTRACT:
Catalytic cracking catalysts which contain a basic alkaline earth metal component in amounts greater than 5 percent by weight (expressed as the oxides) are used to crack hydrocarbon feedstocks that contain substantial quantities of metals such as vanadium, nickel, copper and iron. In a particularly preferred embodiment natural or synthetic particulate magnesium oxide (MgO) containing composites such as dolomite or a formed particulate coprecipitated magnesia-silica cogel (MgO.SiO.sub.2) having a substantial intra-particle pore volume in pores ranging from about 200-10,000 .ANG. in diameter and an average pore diameter greater than about 400 .ANG. in the 200-10,000 .ANG. diameter range is mixed with a zeolite containing fluid cracking catalyst (FCC) either as an integral component of the catalyst particle or as a separate additive.
