20080241059 | Catalytic Steam Reforming With Recycle - A method for generating hydrogen in a production facility having a catalytic steam reformer, a boiler downstream of the catalytic steam reformer, optionally having a prereformer, and optionally having a shift reactor, wherein the reformer feed gas mixture is formed using a steam-containing recycle gas mixture which was formed from boiler effluent. The boiler generates steam which may be used to form the reformer feed gas mixture, used elsewhere in the production facility, and/or used for export steam. | 10-02-2008 |
20090078912 | Method For Determining Carbon Content Of A Hydrocarbon-Containing Mixture - A method for determining a carbon content value of a hydrocarbon-containing mixture. At least one composition-dependent bulk property of the hydrocarbon-containing mixture is measured and optionally at least one non-hydrocarbon component concentration is measured with the resulting measurements used in a carbon content correlation for calculating the carbon content of the hydrocarbon-containing mixture. The carbon content may be used in a hydrogen and/or synthesis gas production process for calculating a target flow rate of steam to be combined with the hydrocarbon-containing mixture to form a mixed feed having a target steam-to-carbon ratio. | 03-26-2009 |
20090104110 | Staged Hydrocarbon/Steam Reformer Apparatus And Method - A staged steam hydrocarbon reformer is disclosed having a chamber within which convectively heated reformer stages are enclosed. The reformer stages are tubes containing steam reforming catalyst. The stages are in serial fluid communication with one another through mixing vessels positioned between each stage. The first reforming stage is fed a mixture of steam and a gaseous hydrocarbon. Partially reformed gases having increased hydrogen concentration are produced at each stage and are mixed with additional gaseous hydrocarbon and optionally steam in the mixing vessels. Collection and distribution manifolds provide fluid communication between the reformer stages and the mixing vessels. A method is also disclosed in which partially reformed gases from a preceding stage are mixed with gaseous hydrocarbon and steam having a lower steam to carbon ratio than the fresh feed to the previous stage. | 04-23-2009 |
20090220393 | IN-SITU GASIFICATION OF SOOT CONTAINED IN EXOTHERMICALLY GENERATED SYNGAS STREAM - A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO | 09-03-2009 |

20100224834 | Method For Determining Carbon Content Of A Hydrocarbon-Containing Mixture - A method for determining a carbon content value of a hydrocarbon-containing mixture. At least one composition-dependent bulk property of the hydrocarbon-containing mixture is measured and optionally at least one non-hydrocarbon component concentration is measured with the resulting measurements used in a carbon content correlation for calculating the carbon content of the hydrocarbon-containing mixture. The carbon content may be used in a hydrogen and/or synthesis gas production process for calculating a target flow rate of steam to be combined with the hydrocarbon-containing mixture to form a mixed feed having a target steam-to-carbon ratio. | 09-09-2010 |
20100264373 | PROCESS FOR PRODUCING A HYDROGEN-CONTAINING PRODUCT GAS - A process for producing a hydrogen-containing product gas by catalytic steam-hydrocarbon reforming with an overall steam-to-carbon molar ratio between 1.5 and 2.4 for the process. The process stream is reacted in at least two prereformers prior to reaction in catalyst-containing tubes in a top-fired reformer furnace. The process stream is reacted adiabatically in the first prereformer, while the process stream is heated prior to being introduced into the second prereformer and/or the second prereformer is heated. The process avoids carbon formation on the catalyst in the catalyst-containing tubes in the primary reformer. | 10-21-2010 |
20120104321 | Steam-Hydrocarbon Reforming with Limited Steam Export - A steam-hydrocarbon reforming process and apparatus wherein reformate from a prereformer is reacted in a gas heated reformer which is heated by reformed gas from a primary reformer. Reformate from the gas heated reformer is passed to the primary reformer as feed gas. | 05-03-2012 |
20120282145 | Steam-Hydrocarbon Reforming with Limited Steam Export - A steam-hydrocarbon reforming process and apparatus wherein reformate from a prereformer is reacted in a gas heated reformer which is heated by reformed gas from a primary reformer. Reformate from the gas heated reformer is passed to the primary reformer as feed gas. | 11-08-2012 |
