✦ Synopsis

A gas pumping system for ITER, improved by implementation of superpermeable membranes for selective hydrogen isotope exhaust, is considered. A study of the pumping capability of a niobium membrane for a hydrogen-helium mixture has been performed.

Monte Carlo simulations of gas behaviour for the experimental facility and fusion reactor have been done. The scheme of the ITER pumping system with the membranes and membrane pumping technology was considered. The conceptual study the membrane pump for the ITER was done. This work gives good prospects for the membrane pumping use in ITER to reduce the total inventory of tritium necessary for reactor operation.

Methanol steam reforming in supported Pd

Methanol steam reforming in supported Pd membrane reactor The supported Pd membrane is promising for the production of high-purity hydrogen from catalytic steam reforming of methanol. At the 35°C reaction temperature, the catalyst activity and stability are promoted by increasing the alumina content. Here a compact doublejacketed reactor has generated high-purity hydrogen directly from steam reforming of methanol, with no need for external purification and a much higher recovery yield.
