ABSTRACT:
Carbonous materials such as subbituminous coal, oil-shale, lignite and peat are converted to liquid and gaseous products by (a) impregnating the material with a water soluble salt of a metal selected from the group consisting of iron and zinc, (b) precipitating said metal in as its oxide or a form which can be readily converted to its oxide, and (c) pyrolyzing the treated material at a temperature from about 400.degree. C. to 600.degree. C. at short gas residence times and long solids residence times.
