Experimental investigation of a microchannel membrane configuration with a 1.4μm Pd/Ag23wt.% membrane—Effects of flow and pressure

Non-Pd BCC alloy membranes for industrial hydrogen separation

“…Research is therefore being driven in two directions: firstly, to the development of Pd-alloy membranes of ever-decreasing thickness [7][8][9], and secondly, to the development of alloy membranes containing little or no palladium. Several thorough reviews of Pd-alloy membranes [5,10] have been published, as well as numerous articles detailing performance, fabrication and durability.…”

Dry reforming of methane in membrane reactors using Pd and Pd–Ag composite membranes on a NaA zeolite modified porous stainless steel support

“…This behavior is characteristic of the hydrogen transport through a dense Pd-based alloy membrane, known as the solution-diffusion mechanism (Sievert's law). However, in order to confirm the n-value, it would be interesting to apply higher pressure intervals [20]. The supports offered a low resistance for the hydrogen transport.…”

High-purity H2 production with CO2 capture based on coal gasification

“…Alternatively, these gas phase limitations can be reduced by smart module design in order to optimize feed flow conditions to reduce the thickness of the hydrogen-depleted layer. Microstructured membrane reactors that reduce gas phase diffusion limitations and increase the membrane area to reactor volume ratio compared to traditional tubular reactors, offer in this respect great advantages [43].…”
