ABSTRACT:
A process for removing arsenic and/or selenium from carbonaceous materials. The arsenic and/or selenium are separated by reaction with a metal oxide and/or metal sulfide which is itself derived from a metal complex, and organometallic compound and/or a metal salt of an organic acid which is soluble in said carbonaceous fluid and which either decomposes to the corresponding metal oxide and/or metal sulfide or which can be converted to the corresponding metal sulfide or metal oxide. The reaction of the metal oxide and/or metal sulfide with the arsenic and/or selenium is accomplished at a temperature within the range from about 300.degree. F. to about 800.degree. F. preferably from about 500.degree. F. to about 750.degree. F., most preferably from about 680.degree. F. to about 750.degree. F. and in either an inert or reducing atmosphere. Preferably, the conversion is accomplished in a reducing atmosphere and in the presence of molecular hydrogen.
