Precombustion carbon capture is an effective strategy to reduce large‐scale CO2 emissions, which is mainly used in the area of integrated gasification combined cycle (IGCC) power plants. Oxygen transport membranes (OTMs) were suggested as the air separation unit to produce high purity oxygen for the gasifier. However, the improvement in efficiency was limited. Here, a new IGCC process is reported based on a robust OTM reactor, where the OTM reactor is used behind the coal gasifier. This IGCC‐OTM process fulfills syngas oxidation, H2 production, and carbon capture in one unit, thus a significant decrease of the energy penalty is expectable. The membrane reactor does not use noble metal components, and exhibits high hydrogen production rates, high hydrogen separation factor (103–104), and stable performance in a gas mixture mimicking real syngas compositions from a coal gasifier with H2S concentrations up to 1,000 ppm.

与IGCC集成的高性能氧气传输膜反应器用于碳捕集

预燃烧碳捕集是减少大规模CO 2排放的有效策略,主要用于整体气化联合循环(IGCC)发电厂领域。建议使用氧气传输膜(OTM)作为空气分离单元,为气化炉生产高纯度氧气。但是,效率的提高是有限的。在此,据报道基于鲁棒的OTM反应器的新IGCC工艺,其中OTM反应器用于煤气化炉的后面。该IGCC-OTM工艺可在一台设备中完成合成气氧化,H 2生成和碳捕获,因此可望显着降低能耗。膜反应器不使用贵金属成分,并且具有较高的氢气产生速率和较高的氢气分离系数(103 –10 4),并在混合气体中具有稳定的性能,该混合物模仿了H 2 S浓度高达1,000 ppm的煤气化炉中的真实合成气成分。
