    摘要： A chamber comprising a moving bed of solid particles, delimited by at least one screen with thickness e, circulating in a downward direction substantially parallel to the screen, the bed being traversed by at least one fluid flowing in the bed in a principal direction which is different to that of the ensemble of particles and leaving the bed by an outlet screen. In accordance with the invention, the chamber comprises at least one opening for introducing solid particles located above the bed and comprising at least one orifice for the flow of the particles, located at a distance of at least 0.6 e from the outlet screen. The chamber advantageously comprises at least two extraction openings, one extraction opening being located at a distance not more than 0.5 e from the outlet screen, and the other at a distance of at least 0.5 e from the outlet screen. The invention is applicable to catalytic reactors, in particular to catalytic reforming reactors.

    摘要： The invention relates to an energetically self-sufficient syngas production method in at least one chemical loop. The chemical loop involves at least three distinct oxidation, reduction and gasification reaction zones: 1. at least one air-supplied oxidation reaction zone R1, referred to as “air” reactor, where the reaction of oxidation of the metallic oxides takes place affer reduction, 2. at least one combustion reduction reaction zone R2, referred to as “fuel” reactor, where the feed combustion reaction takes place in the presence of the oxygen present in the metallic oxides, 3. at least one gasification reaction zone R3, referred to as “gasification” reactor, for gasification of the solid and/or liquid feeds in order to produce a syngas, said gasification being catalysed by the at least partly reduced metallic oxides from R2.

    摘要： A process for the production of high purity hydrogen from a naphtha catalytic reformer having a first catalytic zone in a lead position followed by a second catalytic zone in a lag position operating at similar inlet temperatures to produce a predetermined conversion wherein the inlet temperature of the second catalytic zone is reduced to thereby reduce the concentration of carbon monoxide in the net hydrogen product stream and the inlet temperatures of the first catalytic zone is increased to restore the predetermined conversion.
