Abstract (en)
Carbonous materials such as subbituminous coal, oil shale, lignite and peat are converted to liquid and gaseous products by (a) impregnating the material with one or more water soluble salts of iron and/or zinc, preferably the sulfate or chloride thereof, (b) treating, for example by raising the pH or with sodium carbonate, to precipitate the iron and/or zinc as oxide or a form which can be readily converted to oxide, and (c) pyrolyzing the treated material at a temperature from about 400 DEG C to 700 DEG C, and at short gas residence times and long solids residence times, in the presence of hydrogen.
