ABSTRACT:
A method for removing a contaminant comprising at least one of arsenic and selenium from a synthetic crude oil or fraction thereof characterized by mixing with the synthetic crude oil feed (1) particles of a material that is either iron, cobalt, nickel, oxides or sulfides of these metals, or a mixture thereof, and (2) hydrogen, and heating the mixture in a reaction zone to deposit said contaminant(s) on said particles. A liquid product stream comprising the synthetic crude oil without the contaminant(s) is recovered, leaving a thickened slurry. All or a portion of the thickened slurry can be withdrawn from the process and all or a part of the slurry can be mixed with fresh synthetic feed. Also disclosed are specific and preferred process details.
