Claims
- 1. A process for making low sulfur oil from an aqueous charge containing cellulose and other carbohydrates comprising coking said charge at a temperature in the range of 400.degree. to 550.degree. F under a pressure of 300 to 1200 psig for 5 minutes to 2 hours to form an aqueous slurry containing cokes solids; removing from 50 to 99 percent of the liquid from said slurry; contacting the thus concentrated slurry with hot pressurized synthesis gas at a pressure of between about 500 to 5000 psig at a temperature of between 500.degree. to 750.degree. F to form a low sulfur oil, gases and carbon and inorganic solids and separating said oil from said carbon and inorganic solids and gases.
- 2. The process of claim 1 wherein said charge consists of sewage sludge.
- 3. The process of claim 1 wherein a catalytic agent of the group of Na.sub.2 CO.sub.3, NaHCO.sub.3, K.sub.2 CO.sub.3 and KHCO.sub.3 is added to said concentrated slurry.
