Burke, D P

A discussion is presented of new methods for gasoline production from metal-rich crudes and residua; the effects of nickel and vanadium in feedstocks on catalytic cracking catalysts, i.e., catalyzing dehydrogenation reactions leading to methane, hydrogen, and coke; Phillips Petroleum Co.'s heavy oil cracking process, which can accommodate up to 25-30 ppm vanadium and nickel and its metal passivating additive; new metal-resistant fluidized cracking catalysts available from Davison; demetallization of the catalyst with Atlantic Richfield Co.'s Demet III process; residua hydrocracking processes such as Hydrocarbon Research Inc.'s H-Oil and Lummus Co.'s LC-Fining, both of which use an inexpensive catalyst in a first reactor to adsorb metal impurities; Exxon Research and Enginering Co.'s Flexicoking process; and the UOP Inc./Instituto Mexicano del Petroleo Demex solvent extraction process, which precipitates an asphaltic, metal-rich pitch.
