  • Method of purification by means of adsorption with regeneration using a gas containing an undesired component in the purified gas
    Patent number: 9358495
    Abstract: TSA method for purification by means of adsorption of a synthetic gas including hydrogen, CO and/or methane, implementing at least one adsorber having at least one adsorbent and subjected to a pressure cycle comprising at least an adsorption step, a step of producing a flow enriched with a main component and a regeneration step, characterized in that the regeneration step includes: regenerating the adsorbent using a regeneration gas including more than 95 mol of nitrogen; and scavenging the adsorbent using a scavenging gas corresponding to a fraction of the synthetic gas to be purified or a fraction of the purified synthetic gas.
    Type: Grant
    Filed: April 20, 2012
    Date of Patent: June 7, 2016

  • Production of hydrogen from a reforming gas and simultaneous capture of CO2 co-product
    Patent number: 8746009
    Abstract: Process for producing hydrogen from a gas mixture comprising hydrogen, CO2, CO, CH4 and water, employing a CO2 PSA unit, a cryogenic unit and an H2 PSA unit, in which process: a) said gas mixture is introduced into the CO2 PSA unit, producing a CO2-enriched fraction and CO2-depleted fraction; b) CO2-enriched fraction is introduced into the cryogenic unit, producing a CO2-enriched fraction and an H2-enriched fraction; c) the H2-enriched fraction is recycled upstream of the H2 PSA unit; and d) the CO2-depleted fraction coming from step b) is introduced into the H2 PSA unit, producing a hydrogen-enriched stream and a waste gas.
