    摘要: A system for producing hydrogen gas from water decomposition using a thermochemical CuCl cycle, the improvement comprising the use of an insulated hydrogen production reactor comprising a reaction chamber and a separation chamber; the reaction chamber having a hydrogen chloride gas inlet and a solid copper inlet; one or more levels provided in the reaction chamber, the number of which is dependant on production scale and pressure drop; each level comprising a perforated plate with associated filter media, the perforations of the plate and media being of decreasing size from top to bottom of the reaction chamber, and being sized to permit downward flow of the hydrogen gas and molten CuCl products, as well as the HCL gas reactant, and to prevent entrainment of solid copper in the molten CuCl; the separation chamber being located below the reaction chamber and being of greater cross section than the reaction chamber and comprising a first hydrogen removal and entrained copper removal zone and a second molten CuCl removal zone; removal of the reaction products being controlled so as to substantially decrease the amount of entrained copper in the molten CuCl; and the first zone having outlets for removal of hydrogen gas and entrained copper particles, with the second zone having an outlet for removal of molten CuCl.

    摘要: A thermochemical reactor (4) and associated processes are disclosed. The reactor (4) and processes are used to conduct reactions relating to the hydrolysis of cupric chloride (CuCl2) within any one of the five-, four- and three-step Cu—Cl cycles. The reactor (4) comprises a reaction chamber (22) including a first zone (24) configured to conduct a spray operation and a second zone (26) configured to conduct a fluidized, fixed and/or moving bed operation. The first zone (24) includes a first inlet (28) configured to introduce a first reactant and an additional inlet (30) configured to introduce an additional reactant. A distributor (34) is configured to introduce the additional reactant to the second zone (26). One or more product outlets (44, 46) for communication with the reaction chamber (22) are provided.

    摘要: A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu—Cl Cycle. Non-pure water is used as the feedstock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feedstock of industrial processes. The direct usage of this water can significantly reduce water supply costs.
