A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

A method of assembling and/or operating apparatus for undertaking a chemical reaction. The apparatus includes a housing in which a precursor of a receptacle is arranged. A fluid (F1) may be introduced into said precursor to cause the precursor to inflate.

A radiant, non-catalytic recuperative reformer has a flue gas flow path for conducting hot exhaust gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is positioned adjacent to the flue gas flow path to permit heat transfer from the hot exhaust gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, a portion of the reforming mixture flow path is positioned outside of flue gas flow path for a relatively large residence time.

The invention relates to a method particularly for reacting phosgene with compounds that contain hydroxyl, thiol, amino and/or formamide groups, comprising the steps of: (I) providing a reactor which has a first reaction chamber (300, 310, 320, 330, 340, 350) and a second reaction chamber (200, 210, 220, 230, 240, 250, 260), the first and the second reaction chambers being separated from one another by means of a porous carbon membrane (100, 110, 120, 130, 140, 150); (II) providing carbon monoxide and chlorine in the first reaction chamber; and simultaneously (III) providing a compound containing hydroxyl, thiol, amino and/or formamide groups in the second reaction chamber. The porous carbon membrane is configured to catalyse the reaction of carbon monoxide and chlorine to obtain phosgene, and to allow this formed phosgene to pass into the second reaction chamber. The invention also relates to a reactor that is suitable for carrying out the claimed method.

A system and method for producing hydrogen from hydrocarbon and steam, including a membrane reformer with multiple membrane reactors each having a tubular membrane. The bore of the tubular membrane is the permeate side for the hydrogen. The region external to the tubular membrane is the retentate side for carbon dioxide. A sweep gas flows through the bore to displace hydrogen in a direction countercurrent to flow of hydrocarbon and steam in the region external to the tubular membrane. The method includes discharging hydrogen as permeate with the sweep gas from the bore, and discharging carbon dioxide in the region external to the tubular membrane as retentate from the membrane reactor.
