    摘要: The invention provides a process for the separation of CO2 from a gaseous feed stream, comprising the subsequent steps of: a) cooling a porous body in the form of a fixed bed (101,102,103) to a temperature below the sublimation temperature of CO2 to obtain a cold body; b) contacting a gaseous feed stream (120) comprising CO2 and one or more other gaseous compounds with the surface of the cold body to obtain a body comprising solid CO2 and a CO2-depleted effluent gas (124); and c) removing the solid CO2 by exposing the porous body comprising solid CO2 to a fluid CO2 stream (130) having a temperature above the sublimation temperature of CO2 whereby fluid CO2 (136) and a warm porous body are obtained.

    摘要: The invention relates to a process for the production of hydrogen and carbon dioxide from a hydrocarbonaceous feed-stock, comprising: a) supplying a gaseous hydrocarbonaceous feedstock and steam to a reaction zone comprising a steam reforming catalyst and catalytically reforming the hydrocarbonaceous feedstock to produce a reformed gas comprising hydrogen and carbon dioxide; b) supplying a molecular oxygen-comprising gas to the permeate side of a first hydrogen separation membrane; c) contacting a part of the hydrogen with a first hydrogen separation membrane, allowing the hydrogen to permeate through the first hydrogen separation membrane and combusting the hydrogen with the molecular oxygen at a permeate side of the first hydrogen separation membrane to produce all heat necessary for catalytic reforming the hydrocarbonaceous feedstock; d) contacting the remainder of the hydrogen with a second hydrogen separation membrane, which is separate from the first hydrogen separation membrane, and allowing the hydrogen to permeate through the second hydrogen separation membrane to obtain a first effluent comprising a substantially pure stream of hydrogen; and e) removing a stream rich in carbon dioxide from the reaction zone as a second effluent. The invention further related to a reactor for such process and to a fuel cell system comprising in series such reactor and a fuel cell.

    摘要: A process for carrying out a chemical equilibrium reaction is disclosed in which, in a first stage, one or more reactants are contacted with a fixed arrangement of a catalyst under conditions such that the reactants and the products of the reaction are gaseous, the unconverted reactants and products of the first stage being passed to a second stage, in which they are contacted with a fixed arrangement of a catalyst and the reaction allowed to proceed in the presence of an absorbent capable of absorbing a product of the reaction. There is specifically disclosed a process for the synthesis of methanol from carbon monoxide and hydrogen, in which, in a first stage, carbon monoxide and hydrogen are contacted with a fixed arrangement of a catalyst active in catalyzing the synthesis of methanol under conditions such that the methanol formed is present as a gas under the prevailing reaction conditions, the unconverted carbon monoxide and hydrogen and methanol produced in the first stage being passed to a second stage, in which they are contacted with a fixed arrangement of a catalyst active in catalyzing the synthesis of methanol and the reaction allowed to proceed in the presence of an absorbent capable of absorbing methanol.
