| Number | Title | Issue Date |
| 6626981 | Microporous carbons for gas storage A method for producing high capacity gas-storage microporous sorbents involves precursor carbonization under relatively severe heat-treatment conditions, normally followed by activation using a cyclic chemisorption-desorption process.... | 09/30/2003 |
| 6395678 | Bead and process for removing dissolved metal contaminants A bead is provided which comprises or consists essentially of activated carbon immobilized by crosslinked poly(carboxylic acid) binder, sodium silicate binder, or polyamine binder. The bead is effective to remove metal and other ionic contaminants from di... | 05/28/2002 |
| 5858911 | Method of producing activated carbon Disclosed is a rigid fine-celled foam composition and a method of producing it. The foam composition is nontoxic, environmentally friendly, has improved absorption/adsorption and retention of liquids, is not as hard as prior art foams, does not include po... | 01/12/1999 |
| 5723717 | Procedure for the recovery and/or cleaning of carbon formed as a result of combustion processes A procedure for the recovery and/or cleaning of carbon formed as a result of thermal processes. This carbon is present with supernatant C in equilibrium with CO2 and CO (Boudouard equilibrium) after being transformed into CO2 with ox... | 03/03/1998 |
| 4987115 | Method for producing generator gas and activated carbon from solid fuels A method and an apparatus for producing generator gas and activated carbon from solid fuels. A first gasification stage is supplied with fuel by an underfeed charging system and preheated air, the air and fuel being supplied in the same direction. In a se... | 01/22/1991 |
| 4883499 | Process adapted to produce synthesis gas and activated carbon from organic input material An improved gasification system, in which synthesis gas is produced through the operation of a fuel gas production bed comprising an upper layer (66) of organic input material, typically in the form of pellets or briquettes of substantially uniform size a... | 11/28/1989 |
| 4111800 | Process for treating municipal solid waste and raw sewage sludge Raw sewage sludge is combined with a solution of sodium aluminate. Municipal solid waste is then treated with the sludge-aluminate mixture. The treated waste is then carbonized in a furnace.... | 09/05/1978 |
| 4084938 | Process for treating solid carbonaceous fossil fuels and the products thus prepared Solid carbonaceous fossil fuels such as coal, lignite and peat are treated with an aqueous medium containing a novel catalyst to remove undesirable constituents and produce valuable products. The catalyst is prepared by steps including admixing a water so... | 04/18/1978 |
| 4038154 | Pile furnace A furnace and process for carrying out the carbonizing and/or activating of charcoal and similar operations includes vent means, which may be in the general shape of one or more elongated chambers of tunnels, that acts in combination with air admission me... | 07/26/1977 |
| 4026795 | Method for the regeneration of activated carbon Method for the regeneration of an activated carbon having adsorbates adsorbed therein characterized by removing the adsorbates by liquid dimethyl ether or a mixture of liquid dimethyl ether and water. By such method, the spent carbon can be effectively re... | 05/31/1977 |
