| 20090177023 | FILTRATION TRAY FOR FIXED BED REACTOR WITH A CO-CURRENT DOWN-FLOW OF GAS AND LIQUID - The device described in the present invention can trap plugging particles contained in the liquid feed supplying a reactor functioning in gas and liquid co-current down-flow mode using a specific distributor tray comprising a filtration medium. | 07-09-2009 |
| 20090241418 | PROCESS FOR THE PRODUCTION OF HIGHLY THERMALLY-INTEGRATED HYDROGEN BY REFORMING A HYDROCARBON FEEDSTOCK - The invention relates to a process for the production of highly thermally-integrated hydrogen by reforming a hydrocarbon feedstock that comprises a stage a wherein a stream of air or water, whose temperature is less by at least 200° C. than the combustion temperature inside a burner, is mixed with the effluent that is obtained from said burner, so as to reduce the temperature of this effluent to less than 725° C.; a stage b wherein the mixture that is obtained from stage a enters a first heat exchanger and is used to superheat at least one stream of water vapor and/or hydrocarbon feedstock in gaseous form, whereby said stream that is thus superheated by indirect heat exchange is injected directly into a reforming reactor where it is used as a fuel; and a stage c wherein the mixture that is obtained from stage b enters a second heat exchanger and is used to totally evaporate a stream of liquid water and/or hydrocarbon feedstock. | 10-01-2009 |
| 20090241419 | START-UP PROCESS FOR A UNIT FOR PRODUCING HIGHLY THERMALLY-INTEGRATED HYDROGEN BY REFORMING A HYDROCARBON FEEDSTOCK - The invention relates to a start-up process for a unit for producing highly thermally-integrated hydrogen by reforming a hydrocarbon feedstock that comprises a stage a wherein a burner whose purpose is to ensure start-up is supplied with a mixture of hydrocarbon feedstock and air, a stage b wherein a water stream is evaporated by indirect heat exchange with at least one of the hot streams of the process, a stage c wherein the hydrocarbon feedstock to be reformed is evaporated and heated and then introduced in gaseous form in a reforming reactor, and a stage d wherein the start-up burner is shut down, and a burner that is in permanent operation is lit. | 10-01-2009 |
| 20090272301 | DEVICE FOR CONTROLLING THE RADIAL PROFILE OF THE TEMPERATURE OF A CONFINED GAS STREAM - This invention describes a new device for controlling the radial profile of the temperature of a confined gas stream that is designed to be used as a coolant in an exchanger that is located downstream from said device. | 11-05-2009 |
| 20100010278 | PROCESS FOR SELECTIVE HYDROGENATION ON A GOLD-CONTAINING CATALYST - The invention relates to a process for selective hydrogenation by bringing a so-called C2 fraction feedstock into contact with a fixed catalyst bed, whereby said catalyst comprises a substrate and a metal phase that consists of either gold or palladium and gold with a molar ratio of gold to palladium of greater than 5, whereby the contact is carried out in the presence of a solvent that comprises at least one aromatic hydrocarbon, whereby the products that are obtained at the end of the selective hydrogenation can be separated from the solvent by distillation. | 01-14-2010 |
| 20100015018 | Treatment or Hydrotreatment Reactor with a Granular Bed and an Essentially Liquid Phase and an Essentially Gaseous Phase Flowing through the Bed - The present invention relates to a treatment or hydrotreatment reactor comprising at least one granular bed ( | 01-21-2010 |
