现在，正在探索许多技术，以允许化石燃料的组合，而在适合压缩，运输和隔离状态下获得CO 2的捕获是主要的竞争者。使用移位反应产生纯H 2；循环）或在近气温下（例如，胺擦洗）；在存在固体氧化物载体的情况下，燃料会转换氧气燃烧在纯氧气或几乎纯的氧气中燃烧的燃料。使用循环流体床的氧气成分已经越来越多，在西班牙有一个300 MWE植物的计划。化学工业和约翰·威利（John Wiley＆Sons）有限公司
Many technologies are now being explored to permit the combustion of fossil fuels while achieving CO 2 capture in a state suitable for compression, transporting, and sequestration. Among the chief contenders are processes in which the fuel is first decarbonized, usually by gasification, followed by the use of a shift reaction to produce pure H 2 ; post‐combustion capture, in which the CO 2 is removed from the flue gases either at high temperatures (e.g. carbonate or Ca looping) or at near‐ambient temperatures (e.g. amine scrubbing); chemical looping in which the fuel is converted in the presence of a solid oxide carrier, thus producing a stream of gas consisting primarily of CO 2 and H 2 O; and finally, oxyfuel combustion in which the fuel is burned in a stream of pure, or nearly pure, oxygen. The latter technology is already being investigated for application with pulverized fuel or coal, but more recently, the possibility of using oxyfuel combustion with circulating fluidized beds has been receiving increasing attention. There is already a 30 MWth demonstration unit operating in Spain, with plans to build a 300 MWe plant. This perspective describes the current status of oxyfuel research and development. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
