| Number | Title | Issue Date |
| 6463399 | Apparatus and method for detecting rotation angular speed and automobile using the apparatus A rotation angular speed detection apparatus that accurately detects a low rotation angular speed of a rotating body includes: a receiving part for receiving rotation angles at predetermined time intervals from a rotation angle sensor that detects rotatio... | 10/08/2002 |
| 6033528 | Process for making blast furnace coke A blast furnace coal is produced by rapidly heating a coal blend having 10 to 30% by weight of a non-slightly-caking coal having softening initiation temperature T with the balance including a caking coal having softening initiation temperature T0 | 03/07/2000 |
| 5635147 | Process of treating the gasification residue formed by the gasification of solid fuels in a fluidized bed In addition to ash and coke, the gasification residue contains alkaline earth metal sulfide and alkaline earth metal oxide because desulfuring agents have been supplied to the gasifier. At temperatures from 5° to 80° C. the gasification residue is mixed... | 06/03/1997 |
| 4941952 | Process for the treatment of waste material In the treatment of hydrocarbon-containing waste material, in particular plastic-containing waste material, by pyrolysis, gases containing hydrogen halide compounds which are formed are neutralized by the addition of basic additive material. Since the rea... | 07/17/1990 |
| 4871426 | Process for reprocessing waste material A liquid fraction and a gas fraction produced during the reprocessing of waste material containing CH compounds by pyrolysis, have a mass ratio approximately equal to 1. Since the liquid fraction is more suitable for further processing than the gas fracti... | 10/03/1989 |
| 4605421 | Process for the preparation of a carbonaceous-derived solid fuel product A method for producing carbonaceous-derived solid fuel products comprising subjecting a carbonaceous material to a temperature sufficient to remove a substantial portion of water inherent in said carbonaceous material, pyrolyzing at least a portion of the... | 08/12/1986 |
| 4599161 | Retorting process with contaminant removal Hydrogen sulfide issuing from an oil shale retort is captured in an absorbent bed. When the bed is regenerated as with oxygen containing gas, the sulfur dioxide liberated is reintroduced into the retort for reaction with the spent shale.... | 07/08/1986 |
| 4554053 | Method and device for removal of heavy tar from a coke-oven gas during cooling In a method of removing heavy tar produced in a coke oven during the cooling of a coke-oven gas from the coke-oven gas, the heavy tar pieces are crushed in a pulverizer to obtain particles of the size of less than 1 mm. The heavy tar particles are then ra... | 11/19/1985 |
| 4270980 | Method for recovering and utilizing heat of coke-oven gas A method for recovering and utilizing heat of coke-oven gas, which comprises: through heat exchange with a high-temperature coke-oven gas generated from a coke oven battery and containing vaporized coal tar, vaporized low boiling point substances and dust... | 06/02/1981 |
| 4225415 | Recovering hydrocarbons from hydrocarbon-containing vapors Values are recovered from a hydrocarbon-containing vapor by contacting the vapor with quench liquid consisting essentially of hydrocarbons to form a condensate and a vapor residue, the condensate and quench fluid forming a combined liquid stream. The comb... | 09/30/1980 |
| 4158637 | Conversion of coal into hydrocarbons Hydrocarbons are formed of coal and water. The water is converted or dissociated separately into hydrogen and oxygen in a first chemical reactor by thermochemical and/or electrolytic processing. The resulting hydrogen is then reacted with the coal in a se... | 06/19/1979 |
| 4139416 | Carbonaceous material with high characteristics of surface area and activity and process for producing the same A carbonaceous material with high characteristics of surface area and activity is produced in a continuous process by heating and drying ground pit coal at 200 to 300° C. for 15 to 120 minutes in air, and then heating in two further stages in fluidized b... | 02/13/1979 |
| 4086144 | Process and apparatus for the separation of float tars in the tar separator of a coking installation The so-called float tar which floats on the stream of crude tar and ammonia water in the tar separator of a coking installation and which interferes with the clean separation of crude tar and ammonia water is removed by skimming the float tar off the crud... | 04/25/1978 |
