ABSTRACT:
The present invention relates to a method for removing contaminants such as arsenic from a hydrocarbonaceous fluid which consists essentially of the crude, or a fraction thereof, obtained from oil shale, solid coal, or tar sands by non-catalytically heat treating the hydrocarbonaceous fluid at a temperature of from about 20.degree. F. to about 600.degree. F. in the presence of an aqueous solution containing an agent that would convert such contaminants into components soluble in the aqueous solution. Particularly suitable agents to be utilized in the above aqueous solution to remove contaminants such as arsenic are ammonium sulfide type compounds. The purified hydrocarbonaceous fluid may be subjected to a catalytic hydrotreating process.
