SYSTEMS AND METHODS FOR MAINTAINING HYDROGEN-SELECTIVE MEMBRANES DURING PERIODS OF INACTIVITY |
摘要 |
The present disclosure is directed to systems and methods for maintaining hydrogen-selective membranes during periods of inactivity. These systems and methods may include heating and maintaining at least the hydrogen-selective membrane of a hydrogen-producing fuel processing system in a thermally buffered state and/or controlling the chemical composition of the gas streams that may come into contact with the hydrogen-selective membrane. Controlling the chemical composition of the gas streams that may come into contact with the hydrogen- selective membrane may include maintaining a positive pressure of an inert, blanket, reducing, and/or non-oxidizing gas within the membrane separation assembly and/or periodically supplying a reducing gas stream to the membrane separation assembly. These systems and methods may further include periodically supplying a feed stream to a hydrogen-producing region of the hydrogen- producing fuel processing system to produce a mixed gas stream and supplying the mixed gas stream to the membrane separation assembly. |
