Advanced hydrogen separation module

Advanced hydrogen separation module with membrane on catalyst... 

Tokyo Gas Co., Ltd. (TGC) has developed a 40 Nm /h-class membrane reformer system with the world s highest efficiency (a value of 81.4%). The company has demonstrated the use of the hydrogen produced to refuel fuel cell vehicles (FCV), together with CO2 capture at the hydrogen station. An advanced hydrogen separation membrane module consisting of a palladium alloy membrane on a structured porous catalyst, which can be used to produce a membrane reformer that is more compact and less expensive, has also been developed. This chapter introduces the development of these two membrane reformer technologies. 

The proposed scheme of Pre-combustion decarbonation based on the use of membranes for hydrogen separation is expected to have some advantages over the conventional and commercially ready technology, such as superior efiiciency and reduction in overall plant capital cost. Membrane-based systems may represent a real advancement in state-of-the-art H2 and CO2 capture in such power plants however, their real application is closely hnked to the realization of a membrane module that is economically built and maintained, as well as to the improvement of membrane permeance and selectivity.
