Evaluation of the water gas shift reaction in a palladium membrane reactor

Design of (Nb, Mo)40Ti30Ni30 alloy membranes for combined enhancement of hydrogen permeability and embrittlement resistance

“…Membrane separation is the benchmark technology used to separate and purify hydrogen from a mixed or contaminated gas, typically produced by methane steam reforming 1–5 or coal gasification 6–8 . Foremost among the possible choices of metallic membrane materials are Pd-based alloys due to their high catalytic surface property, reasonable hydrogen permeability, good durability and tolerance to syngas species.…”

WGS Reaction in Membrane Reactors

“…In the Pd membrane Piemonte et al [24] investigated the influence of reactor length/diameter ratio, position of membrane inside the reactor on the membrane reactor performance. Pinaccia et al [25] investigated the tubular Pd membrane reactor at higher temperatures, i.e., above 400°C and higher pressures (100-800 kPa). They found that the CO conversion decreases with increasing slenderness ratio.…”

Membrane-integrated oxy-fuel combustion of coal: Process design and simulation

“…In the first step fuel is reformed by steam or oxygen or both, and a mixture of H 2 and CO (syngas) is obtained [13,14]. The produced syngas undergoes a water gas shift reaction where CO is converted to CO 2 and more H 2 is produced [15]. After these reactions H 2 is separated from CO 2 and the produced H 2 is combusted with air in a gas turbine to generate electricity.…”
