| 20080196305 | Continuous hydrogen and alcohol generator from coal - A gas generator with the sole input of air, water and coal that continuously produces hydrogen and carbon monoxide and further reacts these two gases into alcohol. This gas generator/reactor is using its own by-products and is therefore also self sustaining. | 08-21-2008 |
| 20080202028 | System For the Conversion of Carbonaceous Fbedstocks to a Gas of a Specified Composition - The present invention provides a carbonaceous feedstock gasification system with integrated control subsystem. The system generally comprises, in various combinations, a gasification reactor vessel (or converter) having one or more processing zones and one or more plasma heat sources, a solid residue handling subsystem, a gas quality conditioning subsystem, as well as an integrated control subsystem for managing the overall energetics of the conversion of the carbonaceous feedstock to energy, as well as maintaining all aspects of the gasification processes at an optimal set point. The gasification system may also optionally comprise a heat recovery subsystem and/or a product gas regulating subsystem. | 08-28-2008 |
| 20090038222 | Upright Gasifier - A generally upright reactor system for gasifying a feedstock. The reactor system generally includes a main body, at least two inlet projections extending outwardly from the main body, and at least one inlet positioned on each of the inlet projections. Each of the inlets is operable to discharge the feedstock into the reaction zone. | 02-12-2009 |
| 20090165376 | Steam Generating Slurry Gasifier for the Catalytic Gasification of a Carbonaceous Feedstock - Steam generating gasification reactors for providing high-pressure and high-temperature steam for catalytic gasification of a carbonaceous feedstock can be based on oxygen blown gasification reactors adapted for processing a slurry feedstock comprising at least 40% water. The exhaust from the slurry gasifier comprises at least steam, carbon monoxide and hydrogen. The slurry composition and the oxygen to fuel ratio can be varied to control the ratio of carbonaceous gases in the generator exhaust. By directing substantially all of exhaust gases produced from the slurry gasification reactor through the catalytic gasifier and subsequent gas separation and sequestration processes, a greatly higher energy efficiency and decreased carbon footprint can be realized. | 07-02-2009 |
| 20110162276 | METHOD AND APPARATUS TO TRANSPORT SOLIDS - A method of operating a gasification facility includes channeling a conveying fluid at a first temperature through at least one first steam heating device to increase the temperature of the conveying fluid to a second predetermined temperature. The method also includes channeling the conveying fluid at the second predetermined temperature through a second steam heating device to increase the temperature of the conveying fluid to a third predetermined temperature. The method further includes channeling the conveying fluid at the third predetermined temperature to a solids conveyance system. Solids become entrained within the conveying fluid. The method also includes transporting at least a portion of the solids to a gasification system. | 07-07-2011 |
| 20110179712 | METHOD AND APPARATUS TO PREHEAT SLURRY - A method of operating a gasification facility includes channeling steam into a grinding mill via a flow control device and a conduit. The method also includes mixing carbonaceous fuel, preheated water, and steam within the grinding mill, to form a preheated coal slurry stream. | 07-28-2011 |
