Testing membrane reactors at scale: steam reforming experiments with 8 Pd membrane tubes of 50 cm length

摘要

As a highly hydrogen-selective membrane, Pd membrane shows a great potential for H_2 production and CO_2 capture when integrated in the WGS or steam reforming membrane reactor, where the chemical reaction and H_2/CO_2 product separation occur at the same time. The reactions can be carried out more efficiently as the equilibrium will be shifted due to the selective removal of H_2. When combined in a natural gas fired power plant, these reactors allow for power production from the hydrogen stream while simultaneously CO_2 is captured in the retentate side and available for underground storage.
