Dear Ken and All: The water-gas reaction is C + H2O ==> CO + H2 Great reaction that converts water and a solid fuel (coal, coke, charcoal) into gaseous fuel. Temperature needs to be above about 800 C. However, the reaction is VERY endothermic (absorbs heat) and needs to have large quantities of heat supplied. This was done with coal in the water-gas process. Air was blasted into coke to get it hot ("the blow"), then steam was blasted through to make "blue water gas" (CO plus H2, "the run"). Read all about it in the 1950 Enc. Brittanica at many libraries.
