摘要： A tubular hydrogen permeable metal membrane and fabrication process comprises obtaining a metal alloy foil having two surfaces, coating the surfaces with a metal or metal alloy catalytic layer to produce a hydrogen permeable metal membrane, sizing the membrane into a sheet with two long edges, wrapping the membrane around an elongated expandable rod with the two long edges aligned and overlapping to facilitate welding of the two together, placing the foil wrapped rod into a surrounding fixture housing with the two aligned and overlapping foil edges accessible through an elongated aperture in the surrounding fixture housing, expanding the elongated expandable rod within the surrounding fixture housing to tighten the foil about the expanded rod, welding the two long overlapping foil edges to one another generating a tubular membrane, and removing the tubular membrane from within the surrounding fixture housing and the expandable rod from with the tubular membrane.

摘要： Apparatus and method for simultaneous recovery of hydrogen from water and from hydrocarbon feed material. The feed material is caused to flow over a heated catalyst which fosters the water-gas shift reaction (H.sub.2 O+COH.sub.2 +CO.sub.2) and the methane steam reforming reaction (CH.sub.4 +H.sub.2 O3 H.sub.2 +CO). Both of these reactions proceed only to partial completion. However, by use of a Pd/Ag membrane which is exclusively permeable to hydrogen isotopes in the vicinity of the above reactions and by maintaining a vacuum on the permeate side of the membrane, product hydrogen isotopes are removed and the reactions are caused to proceed further toward completion. A two-stage palladium membrane reactor was tested with a feed composition of 28% CQ.sub.4, 35% Q.sub.2 O (where Q=H, D, or T), and 31% Ar in 31 hours of continuous operation during which 4.5 g of tritium were processed. Decontamination factors were found to increase with decreasing inlet rate. The first stage was observed to have a decontamination factor of approximately 200, while the second stage had a decontamination factor of 2.9.times.10.sup.6. The overall decontamination factor was 5.8.times.10.sup.8. When a Pt/.alpha.-Al.sub.2 O.sub.3 catalyst is employed, decoking could be performed without catalyst degradation. However, by adjusting the carbon to oxygen ratio of the feed material with the addition of oxygen, coking could be altogether avoided.
