Preliminary pyrolysis of high-ash, high-sulfur oil shale feeds was used to eliminate corrosion and abrasion problems in steam boilers. Pulverized shale was carried through a five-zone tube reactor in a stream of air. Gas samples were removed and analyzed at the end of each zone. Aromatics were absorbed on special coal char. Increasing the temperature from 700 to 850/sup 0/C increased the rate of shale decomposition. The maximum yield of pyrolysis benzene was at 800/sup 0/C, and the yield of pyrolysis gas of high heat value increased with temperature. Combining powerplants with pyrolysis could extend fuel resources and produce materials for chemicals.
