Arc gasification of coal |
摘要 |
A process for the gasification of coal consisting essentially of forming a free-burning arc discharge between at least one anode and a cathode having a conical tip, wherein said arc discharge forms a contraction of the current-carrying area in the transition region in the vicinity of the cathode, forcefully projecting a reactive material consisting of a mixture of pulverized coal and steam parallel to the surface of said conical tip of said cathode and through said contraction of the current-carrying area in the transition region in the vicinity of the cathode, at such a rate that said mixture of pulverized coal and steam is exposed to the free-burning arc for less than 3 milli-seconds, and recovering a solid carbonaceous fume having a surface area equivalent to a particle size in the range of 0.01 to 0.2 microns and a gaseous product comprising of hydrogen, carbon monoxide and carbon dioxide. The carbonaceous fume is highly reactive and in a second steam treatment step is readily converted to gas at a rate of an order of magnitude higher than that for a conventionally devolatilized coal char.
