Fabrication of silicon carbide sintered supports and silicon carbide membranes

Abstract

Efficient separation of hydrogen (H?) under high temperatures and pressures is important to the development of the clean-energy industry, and has been among the key drivers for research on inorganic membranes for the last two decades. Although substantial efforts have been devoted to date to the preparation of nanoporous membranes for H? separation, the fabrication of high-temperature and steam-stable inorganic membranes with high hydrogen fluxes and large separation factors still remains a key challenge. Among all the potential candidates, silicon carbide (SiC) membranes show potential advantages for use in hydrogen separation processes under harsh and corrosive conditions such as, for example, the steam reforming and the water gas shift reactions commonly employed in H? production
