Abstract
Trace metals, particularly As, Fe and Ni, are removed from hydrocarbonaceous oils, particularly shale oil by contacting the shale oil with quadrolobe alumina with or without a processing gas such as hydrogen or nitrogen at 500.degree. F. to 800.degree. F. at 250 to 750 psig and LHSV of 0.4 to 3.0 to deposit a portion of said trace metal onto said alumina and recover an oil product having substantially reduced amounts of trace metal.
