Abstract
There is provided a method and catalyst for removing catalyst-poisoning impurities or contaminants such as arsenic, iron and nickel from hydrocarbonaceous fluids, particularly shale oil and fractions thereof. More particularly there is provided a method of removal of such impurities by contacting the fluids with a copper-Group VIA metal-alumina catalyst. For example, a copper-molybdenum-alumina catalyst may be used as a guard bed material in a step preceding most refining operations, such as desulfurization, denitrogenation, catalytic hydrogenation, etc.
Claims16
A method for reducing the arsenic, nickel and iron content of a hydrocarbonaceous fluid, said method comprising:
- contacting said fluid with a particulate catalyst consisting essentially of an oxide or sulfide of copper and an oxide or sulfide of a Group VIA metal on a porous alumina support in the presence of hydrogen under sufficient metal reducing conditions.
