2020-06-18: Progress on high-performance of oxygen transport membrane reactors integrated with IGCC for carbon capture
Our group developed a new IGCC process based on a robust oxygen transport membrane (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 stable performance in a gas mixture mimicking real syngas compositions from a coal gasifier with H2S concentrations up to 1,000 ppm. This work has been published in AIChE Journal, 2020, 66, e16247.
