Abstract The Bureau of Mines studied the conversion of a variety of cellulosic wastes for example, sawdust, bovine manure, sewage sludge, urban refuse (free of metal and ceramics), etc., to heavy oils. The reactions took place in the presence of synthesis gas and water or carbon monoxide and water under conditions of elevated temperatures and pressures. Waste conversions above 90 percent, often near 99 percent, with oil yields in the range of 40 to 60 percent, were obtained in the temperature range of 250 to 425C and pressure range of 1,500 to 4,000 psig. Cobalt molybdate on alumina catalyst, used with sodium carbonate, gave a product of lower viscosity and lower oxygen content than when using sodium carbonate as the sole catalyst.
