摘要:
The invention relates to a method and to a plant for producing high-purity oxygen, said method comprising a chemical loop wherein circulates a fluidized bed material having the capacity to release gaseous oxygen through oxygen partial pressure lowering, at a temperature ranging between 400° C. and 700° C. The oxygen thus produced can be used in applications such as oxycombustion methods, production of syngas under pressure or FCC catalyst regeneration.
摘要:
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.
摘要:
The invention describes a porous composite material that comprises a porous substrate based on a refractory inorganic oxide in which said substrate has a zeolite crystal content that is less than 25% by mass, whereby said crystals are dispersed homogeneously in the pores of said substrate, and the distribution coefficient that is measured by Castaing microprobe is between 0.75 and 1.25, and in which the total pore volume of said substrate represents at least 40% of the initial total pore volume of the substrate, and the mean diameter of the pores represents at least 50% of the mean diameter of the pores of the initial substrate, its process for preparation and its use as catalyst in the hydrocarbon feedstock conversion reactions.
