Abstract (en)
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 a formed particulate coprecipitated magnesia-silica cogel (MgO.SiO2) having a substantial intra-particle pore volume in pores ranging from about 20-10,000 A DEG in diameter and an average pore diameter greater than about 400 A DEG in the 20-10,000 A DEG 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.
