Filed:

Mar 1, 1985

Appl. No.:

6/707258

Inventors:

Robert L. Savage - Athens OH

International Classification:

C01B 3102
C09C 148
C07C 102

US Classification:

423449

Abstract:

Commercially acceptable carbon black may be produced from coal or other carbonaceous material with the ash content in the resultant product kept below approximately one percent (1%) by controlling the oxygen to coal weight ratio so that it is less than 0. 4 and by starting the process with coal or other carbonaceous material in a size range of from 75 to 1700 microns.

Abstract:

The inorganic and organic desulfurization of solid carbonaceous material at elevated temperatures is increased significantly in the presence of copper. The copper serves as a scavenger for the hydrogen sulfide formed to insure a low hydrogen sulfide concentration for the inorganic desulfurization. In addition, in the presence of ethanol or hydrogen, the organic desulfurization of solid carbonaceous material is improved dramatically by the catalytic influence of the copper on the ethanol dehydrogenization and of the copper sulfide formed on the hydrodesulfurization reactions.
