    • A process for burning coal to produce substantially pure hydrogen for use in fuel cells, together with “sequestration ready” carbon dioxide and a stream of oxygen depleted air for powering gas turbines, characterized by using a combination of two fluidized bed reactors and a third transfer line reactor, the first reactor being supplied with coal particles or “char” and fluidized with high temperature steam; the second reactor being fluidized with high temperature steam and the third reactor being fluidized by compressed air. Solids circulated among these three reactors include a mixture of materials containing calcium compounds (present as CaO, CaCO3 and mixtures thereof) and iron compounds (present as FeO, Fe2O3 and mixtures thereof). The coal is gasified by the steam in the presence of CaO to produce CaCO3 and relatively pure hydrogen for use in fuel cells per a CO2 acceptor process. Because only part of the coal char input to the first reactor is gasified to produce hydrogen, the remainder can be burned to supply thermal energy necessary to regenerate the CaCO3 back to CaO. Carbon in the middle bed fluidized bed reactor reacts with Fe2O3 in the third reactor and the temperature in the middle fluidized bed reactor is sufficiently high to decompose CaCO3 back into CaO.
    • 一种用于燃烧煤以生产用于燃料电池的基本上纯的氢的方法,以及“隔离准备好”的二氧化碳和用于为燃气轮机供电的耗氧空气流,其特征在于使用两个流化床反应器和第三次转移 第一反应器供应煤颗粒或“炭”并用高温蒸汽流化; 第二反应器用高温蒸汽流化,第三反应器被压缩空气流化。 在这三个反应器中循环的固体包括含有钙化合物(以CaO,CaCO 3及其混合物存在)和铁化合物(以FeO,Fe 2 O 3及其混合物存在)的材料的混合物。 煤在CaO的存在下被蒸汽气化以产生CaCO 3和相对纯的氢气,用于每个CO2受体过程的燃料电池。 由于仅输入到第一反应器的煤焦炭的一部分被气化以产生氢气,所以其余部分可被燃烧以提供再生CaCO3所需的热能回到CaO。 中间床流化床反应器中的碳与第三反应器中的Fe 2 O 3反应,中流化床反应器中的温度足够高以将CaCO3分解成CaO。

    • A new cost effective and thermally efficient process for converting nearly valueless resources, such as “static,” lower quality sour natural gas containing hydrogen sulfide, to useable fuels and chemicals, such as hydrogen, methanol and high cetane diesel fuel. The preferred method and apparatus can be used to treat conventional sour gas, i.e., gas having a ratio of H2S to CH4 of at least 0.1 moles and preferably of at least 0.33 moles/mole, using a reforming catalyst and a sulfur capture agent. The process nominally can be carried out using two reactors that repeatedly cycle reactants between two basic process steps—reforming, and air regeneration.
    • 将几乎无价值资源(例如“静态”,含硫化氢的低质量酸性天然气)转化为可用的燃料和化学物质(如氢气,甲醇和高十六烷值的柴油)的新型成本效益和热效率的过程。 优选的方法和装置可用于使用重整催化剂和硫捕获剂来处理常规的酸性气体,即H 2 S与CH 4的比例为至少0.1摩尔,优选至少0.33摩尔/摩尔的气体。 该方法名义上可以使用在两个基本工艺步骤(重整)和空气再生之间重复循环反应物的两个反应器进行。
