Title: Process for treating arsenic-containing hydrocarbon feedstocks

Abstract: Oil-soluble nickel, cobalt, or copper-containing additives are blended with a hydrocarbon feedstock containing arsenic, and the resulting solution is heated to at least 300.degree. F to convert a large proportion of the arsenic to forms removable by conventional filtration or desalting techniques. Preferably, the feedstock-additive solution is heated to at least 500.degree. F and is then distilled so as to produce one or more distillate fractions consisting of components that boil at atmospheric pressure at temperatures in the range 400.degree.-900.degree. F; such distillate fractions will contain arsenic in a concentration less that 20% of that of the feedstock.
