“…Among them, electroless plating is the most extensively used method owing to its cost efficiency and ability of covering supports with complex geometries [23]. It should be noted that the selectivity for H 2 of metallic composite membranes is commonly measurable, which is different from dense metallic homogeneous membranes.…”

“…Reported in Figure 4 is an elaboration of the literature data summarized by Oyama et al [53] for several supported Pd-alloy thin-film membranes in terms of permeance versus temperature of operation or film thickness. The data are quite spread (a common observation for the performance of Pd-based membranes) but, generally, the permeance improves on decreasing the film thickness and increasing the operating temperature.…”

Catalytic Partial Oxidation and Membrane Separation to Optimize the Conversion of Natural Gas to Syngas and Hydrogen

The multistep integration of hydrogen-selective membranes into catalytic partial oxidation (CPO) technology to convert natural gas into syngas and hydrogen is reported. An open architecture for the membrane reactor is presented, in which coupling of the reaction and hydrogen separation is achieved independently and the required feed conversion is reached through a set of three CPO reactors working at 750, 750 and 920 °C, compared to 1030 °C for conventional CPO technology. Obtaining the same feed conversion at milder operating conditions translates into less natural gas consumption (and CO(2) emissions) and a reduction of variable operative costs of around 10 %. It is also discussed how this energy-efficient process architecture, which is suited particularly to small-to-medium applications, may improve the sustainability of other endothermic, reversible reactions to form hydrogen.

“…Metallic membranes for hydrogen separation have been widely probed with Pd‐alloy membranes as the state of the art due to their high permeability and infinite selectivity toward H 2 at intermediate temperature regime (300°C–500°C) . Supporting Information Table S1 (in Appendix S1) summarizes the hydrogen flux values of several typical metallic membranes including Pd, Pd‐Ag, Pd‐Cu, and Ni reported in literature . Pd‐based membranes have the unavoidable shortcomings such as high material cost, susceptibility to damage by CO, hydrocarbon, and sulfur contaminants, and significant hydrogen embrittlement .…”

Cost‐effective and robust nickel (Ni) membrane for H2 separation is a promising technology to upgrade the conventional H2 industries with improved economics and environmental benignity. In this work, Ni hollow fibers (HFs) with one closed end were fabricated and assembled into a membrane module for pure H2 separation by applying vacuum to the permeate side. The separation behavior of the HF module was investigated both experimentally and theoretically. Results indicate that H2 recovery can be improved significantly by changing the operation conditions (temperature or feed pressure). Ni HF is a promising membrane geometry, but the negative effect of pressure drop when H2 passes through the lumen cannot be ignored. Under the vacuum operation mode, there is little difference in term of H2 recovery efficiency whether the feed gas flow is controlled in countercurrent or recurrent operation. This work provides important insight to the development of superior membrane H2 separation system. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3662–3670, 2018
