    • A chemical-looping system utilizes oxygen-earner particles to produce syngas from carbonaceous fuels. The system provides a circuitous flow path for the oxygen-carrier particles, which are used to partially oxidize the fuel to produce syngas. The circuitous flow path can proceed through a plurality of unit operations, including a reducer, a conversion reactor, an oxidizer, and a combustor. The conversion reactor is designed to partially oxidize carbonaceous fuel in co-current flow with the oxygen-carrier particles to produce syngas. In embodiments including an oxidizer, the oxidizer is designed to at partially re-oxidize the carrier particles, yielding hydrogen that can be mixed with partially oxidized products from the conversion reactor to adjust syngas quality. Reactions carried out in the combustor are highly exothermic and yield thermal energy that is absorbed by the carrier particles. The absorbed energy is used at other parts of the process, including the conversion reactor, to drive endothermic reactions.
    • 化学循环系统利用含氧颗粒从碳质燃料中产生合成气。 该系统为氧载体颗粒提供了迂回的流动路径,其用于部分氧化燃料以产生合成气。 迂回的流动路径可以通过多个单元操作进行,包括减速器,转化反应器,氧化器和燃烧器。 转化反应器设计成与氧载体颗粒同时流动地部分地氧化含碳燃料以产生合成气。 在包括氧化剂的实施方案中,氧化剂被设计为部分地再次氧化载体颗粒,产生可以与来自转化反应器的部分氧化产物混合以调节合成气质量的氢。 在燃烧器中进行的反应是高度放热的并产生被载体颗粒吸收的热能。 吸收的能量用于该方法的其它部分,包括转化反应器,以驱动吸热反应。
