Publication number: 20060057060Abstract: A method of producing a synthesis gas which contains hydrogen and carbon dioxide. A hydrocarbon mioxture is pre-reformed to create a first mixture. The first mixture is then reformed in a catalytic ceramic membrane reactor (RCMC) with oxidizing an oxidizing mixture to form a raw synthesis gas. The oxidizing mixture contains oxygen, and the raw synthesis gas contains hydrogen, carbon monoxide, carbon dioxide, water, and an oxygen depleted mixture. Several of the process streams are also preheated. The oxidizing mixture is brought to a temperature between 871° C. and 1300° C. prior to the formation of the raw synthesis gas.Type: ApplicationFiled: November 14, 2003Publication date: March 16, 2006Applicant: L'Air Liquide, Societe' Anonyme a Directoire et Conseil de Surveillance pour l'EtudeInventors: Lian-Ming Sun, Pierre-Robert Gauthier, Pascal Marty, Catherine Denis, Raphaelle Imbault

Patent number: 6402814Abstract: The regeneration phase of the adsorption cycle includes a depressurization step, a heating/elution step, during which the bed is purged with a hot heating/elution gas, and a cooling/elution step, during which the bed is purged with a cold cooling/elution gas. The cooling/elution step is terminated while the cooling/elution gas leaving the bed is at a temperature markedly higher than the temperature of the gas to be treated and the adsorption phase comprises an initial adsorption step during which the bed is cooled down to the low adsorption temperature due to the effect of the gas to be treated.Type: GrantFiled: October 5, 2000Date of Patent: June 11, 2002Assignee: L'Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Georges Kraus, Patrick Le Bot, Lian-Ming Sun

Patent number: 6332915Abstract: A PSA, especially VSA, plant for separating a gas stream, operating in a production cycle and comprising at least one adsorber, preferably two or three adsorbers, and several valves having long and heterogeneous operating times. More specifically, the average operating time (&mgr;) of the valves is such that: 0.5 s<&mgr;<2 s and the operating time (&Dgr;t) of each of the valves is such that: &mgr;−x<&Dgr;t<&mgr;+x, with 0.1 s<x<0.5 s. The invention also relates to the use of such a PSA plant for producing a gas stream rich in oxygen, in nitrogen or in hydrogen, particularly a stream comprising more than 80% oxygen, which is then sent to an oxygen-consuming plant chosen from a combustion furnace, a paper-pulp manufacturing unit and a water treatment unit.Type: GrantFiled: November 8, 1999Date of Patent: December 25, 2001Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Dominique Rouge, Stephane Chantagrel, Lian-Ming Sun, Celine Graciannette, Yves Torre
