20080216406 | METHOD OF GASIFICATION BURNER ONLINE FEEDING - A method of gasification burner online feeding for a coal-water slurry gasifier, where a coal-water slurry line and an oxidizer line are both protected by shield gas. The method may realize online, pressurized and continuous feeding of the gasification burners which are fixed after they stalled for other reasons than their own, thus greatly reducing the probability of accidental shutdown of gasifiers and improving the reliability of long-term service of the multi-nozzle opposed gasifier. | 09-11-2008 |
20090199478 | Process for improved gasification of fuel solids - The invention provides a process that comminutes fuel solids in a steam-driven shear field, with controlled water content and catalyst, with gasification of the particles entrained in the vented steam. Unlike conventional gasification methods the invention requires no dioxygen to be present, and produces dry friable ash that has significant marketable value as a material in its own right. | 08-13-2009 |
20090235587 | METHODS AND SYSTEMS FOR PRODUCING SYNGAS - Methods and systems are provided for producing syngas utilizing heat from thermochemical conversion of a carbonaceous fuel to support decomposition of at least one of water and carbon dioxide using one or more solid-oxide electrolysis cells. Simultaneous decomposition of carbon dioxide and water or steam by one or more solid-oxide electrolysis cells may be employed to produce hydrogen and carbon monoxide. A portion of oxygen produced from at least one of water and carbon dioxide using one or more solid-oxide electrolysis cells is fed as a controlled flow rate in a gasifier or combustor to oxidize the carbonaceous fuel to control the carbon dioxide to carbon monoxide ratio produced. | 09-24-2009 |
20100058664 | METHOD FOR PRODUCING COAL GAS - The present invention relates to a method for producing coal gas, including: feeding raw material pulverized coal and a high temperature gasification agent ( | 03-11-2010 |
20110289846 | Process of Scrubbing Volatiles from Evaporator Water Vapor - A process is provided where a waste stream is directed to an evaporator that produces a vapor having volatile compounds. The vapor including the volatile compounds is directed through a vapor scrubber that contacts the volatile compounds with a scratching solution. The scrubbing solution reacts with the gaseous volatile compounds in the vapor such that the volatile compounds pass from a vapor state into the scrubbing solution and form volatile compounds in the liquid scrubbing solution. The scrubbing solution is collected and recycled. | 12-01-2011 |
20110289847 | Gasification Process - A gasifier waste stream from a gasification process is directed to a solids separator. A portion of the suspended solids in the waste stream is removed in the solids separator, producing slag and fly ash and a grey water effluent. The grey water effluent is directed to one or more ceramic membranes which remove at least portions of the remaining suspended solids in the grey water. Permeate from the ceramic membrane is directed to an evaporator located downstream from the ceramic membrane for further concentration. Placing the ceramic membrane upstream from the evaporator reduces fouling and plugging in the evaporator that would otherwise occur due to the suspended solids in the grey water. | 12-01-2011 |
20110314736 | TREATMENT CHAIN AND PROCESS FOR THE THERMOCHEMICAL CONVERSION OF A WET FEED OF BIOLOGICAL MATERIAL BY GASIFICATION - The invention relates to a treatment chain for thermochemically converting a wet biomass feed ( | 12-29-2011 |
20150376517 | COMPOSITE IRON-SODIUM CATALYST FOR COAL GASIFICATION - Embodiments described herein generally relate to a composite carbonate utilized as a catalyst in coal gasification processes. Methods described herein also include suitable processing conditions for performing coal gasification with the composite catalyst. In certain embodiments the composite catalyst may comprise an alkali carbonate and a transition metal carbonate, for example, an FeCO | 12-31-2015 |
