Patent number: 5458659Abstract: First, nitrogen oxides are reduced by firing coal in substoichiometric air conditions in a first stage oxidation unit of a combustor to reduce NO.sub.x from fuel bound nitrogen. Hydrated lime, Ca(OH).sub.2, is introduced into the first stage oxidation unit to produce calcium sulfide. The calcium sulfide becomes tied up in a slag eutectic which is removed prior to entry of the fuel gas to a second stage oxidation unit at the entrance of a furnace where additional preheated air is added to the fuel gas.Type: GrantFiled: October 20, 1993Date of Patent: October 17, 1995Assignee: Florida Power CorporationInventor: Robert A.

Patent number: 5085764Abstract: In a process for reducing the sulfur and ash contents of coal, coal is sequentially contacted with fused alkali metal caustic, wash water, and acid. Contacting the coal with the caustic produces water-soluble compounds. Sufficient wash water is used to reduce the temperature of the caustic treated coal and dissolve the bulk of the water-soluble compounds before the water-soluble compounds convert to water-insoluble compounds that precipitate on the caustic-treated coal. Caustic removed from the coal by the water is recovered as anhydrous caustic for again contacting coal.Type: GrantFiled: December 19, 1989Date of Patent: February 4, 1992Assignee: TRW Inc.Inventors: Robert A.

Patent number: 5061363Abstract: In a process for the co-processing of waste rubber and carbonaceous material to form a useful liquid product, the rubber and the carbonaceous material are combined and heated to the depolymerization temperature of the rubber in the presence of a source of hydrogen. The depolymerized rubber acts as a liquefying solvent for the carbonaceous material while a beneficial catalytic effect is obtained from the carbon black released on depolymerization the reinforced rubber. The reaction is carried out at liquefaction conditions of 380.degree.-600.degree. C. and 70-280 atmospheres hydrogen pressure. The resulting liquid is separated from residual solids and further processed such as by distillation or solvent extraction to provide a carbonaceous liquid useful for fuels and other purposes.Type: GrantFiled: October 9, 1990Date of Patent: October 29, 1991Assignee: The United States of America as represented by the United States Department of EnergyInventors: Malvina Farcasiu, Charlene M.
