  • PROCESS FOR STEAM REFORMING NATURAL GAS, HAVING TWO COMBUSTION CHAMBERS GENERATING HOT FUMES SUPPLYING THE NECESSARY HEAT TO THE PROCESS AND CONNECTED IN SERIES OR IN PARALLEL
    Publication number: 20170369313
    Abstract: The present invention describes a process for steam reforming natural gas, comprising a steam reforming exchanger-reactor (3000), a reactor for converting CO to CO2 (3100), and a PSA hydrogen purification unit (4300), with a view to producing a synthesis gas in which the heat necessary for the steam reforming reaction is supplied by a first combustion chamber (3100) connected to a second combustion chamber (3200) generating fumes in order to produce a very high degree of thermal integration.

  • Process for dehydration and isomerization of C4 alcohols using an amorphous solid with suitable porosity
    Patent number: 9132414
    Abstract: The present invention relates to a method of producing C4 olefins, from a feed of C4 monohydric alcohol, in which a reaction of dehydration of the monohydric alcohol to at least one olefin, and a reaction of skeletal isomerization of at least one of the olefins produced in one and the same reaction vessel, are carried out in the presence of an alumina-based catalyst with adapted porosity.

  • PROCESS FOR PRODUCING THERMALLY-INTEGRATED HYDROGEN BY REFORMING A HYDROCARBON FEEDSTOCK
    Publication number: 20120164064
    Abstract: The invention relates to a process for producing thermally-integrated hydrogen by reforming a hydrocarbon feedstock, in a reforming reactor, comprising a stage for maintaining the temperature of the effluent that is obtained from the reforming reactor by co-current heat exchange, in a co-current heat exchanger, between the effluent that is obtained from the reforming reactor and the hydrocarbon feedstock that it is desired to reform. The temperature of the synthetic gas exiting the feedstock-effluent exchanger is between 250° C. and 400° C.
