    • Process for the production of hydrogen and the co-production of carbon dioxide in separate streams comprising the following operations: feeding of a solid to a first reaction zone (R1) in which a liquid or gaseous hydrocarbon, preferably natural gas or methane, is also fed, which reacts with the solid fed at its maximum oxidation degree (over-oxidized form), leading to the formation of the combustion products carbon dioxide and water and the solid at its minimum oxidation degree (reduced form); feeding of the solid in reduced form to a second reaction zone (R2) into which water is also fed, which reacts with the reduced form of the solid, producing hydrogen, steam and the solid at an intermediate oxidation degree (oxidized form); feeding of the solid in oxidized form to a third reaction zone (R3) into which air is also fed, obtaining, from the further oxidation of the solid, heat and the solid in over-oxidized form to be recycled to the first reaction zone (R1), wherein the solid contains at least one element selected from elements which, in addition to the metallic state, have at least three different oxidation states and are therefore capable of producing two redox pairs, in order of the oxidation state, characterized in that in the first reaction zone (R1) the solid in over-oxidized form and the liquid or gaseous hydrocarbon are fed in countercurrent.
    • 用于生产氢气和在分开的流中共同生产二氧化碳的方法包括以下操作：将固体进料到第一反应区（R 1），其中液态或气态烃，优选天然气或甲烷为 还进料，其与以最大氧化度（过氧化形式）进料的固体反应，导致燃烧产物二氧化碳和水以及固体以其最小氧化度（还原形式）形成; 将还原形式的固体进料到还被供给水的第二反应区（R 2），其与还原形式的固体反应，以中等氧化度（氧化形式）产生氢气，蒸汽和固体; 将氧化形式的固体进料到也进料空气的第三反应区（R 3），从固体的进一步氧化中得到过热氧化形式的固体，以再循环至第一反应区 （R 1），其中所述固体包含至少一种选自元素的元素，所述元素除了所述金属状态之外具有至少三种不同的氧化态，因此能够以氧化态的顺序产生两个氧化还原对，其特征在于 因为在第一反应区（R 1）中，过氧化形式的固体和液态或气态烃以逆流方式进料。
