Patent number: 8273323Abstract: In a process for producing hydrocarbonaceous educts, the starting material is autothermally gasified by non-catalytic partial oxidation by adding oxygen-containing gas and hydrogen at temperatures of 1200 to 1500° C. and pressures of 15 to 100 barabs to obtain a raw gas containing H2 and CO as main components as well as the components CO2, H2O, CH4 and traces of H2S, COS, CnHm, N2 and Ar, and subsequently the CO contained in the raw gas is converted to CO2 and further H2 by adding steam. An improvement of the process consists in that in a pressure-swing absorption process the converted raw synthesis gas is separated directly, i.e. without passing through a wash for removing CO2 and H2S, into high-purity H2 and into a gas mixture containing H2S, CO2, H2, CO, CH4, Ar and N2, the gas mixture is supplied to the tail gas wash of a Claus process, the H2S separated is introduced into the feed gas of the Claus process, and the waste gas of the tail gas wash, mixed with the tail gas of the Claus process, is burnt.Type: GrantFiled: July 31, 2007Date of Patent: September 25, 2012Assignee: Lurgi GmbHInventors: Holger Schlichting, Thomas Tork

Publication number: 20030095920Abstract: This invention relates to a process as well as a burner for producing carbon monoxide, in which liquid hydrocarbons such as e.g. oil or natural gas are non-catalytically decomposed into carbon monoxide (CO) and hydrogen (H2) at high temperatures. The steam previously used as atomizing and cooling medium is replaced by carbon dioxide, which downstream of the reactor system is separated from the synthesis gas produced and recirculated. To reduce the expenditure of apparatus for providing the gasification medium, the carbon dioxide is withdrawn from the succeeding gas washing, supplied to the burner and expanded through one or more nozzles directly before the orifice opening for the fuel, the differential pressure of the expansion of the carbon dioxide only being 2% to 50% of the reactor pressure.Type: ApplicationFiled: October 29, 2002Publication date: May 22, 2003Inventors: Holger Schlichting, Waldemar Liebner, Rainer Morgenroth, Christoph Erdmann, Gerd Johann Grunfelder, Helmut Fellner, Jurgen Hofmockel
