Multi-tube Pd-Ag membrane module for pure hydrogen production: Comparison of methane steam and oxidative reforming

A maximum hydrogen yield value of 2.8 corresponding to a hydrogen flow rate of 1.20 × 10−3 mol s−1 has been measured during the methane steam reforming at pressure of 350 kPa, GHSV of 864 L(STP) kg−1 h−1 and reformer temperature of 700 °C.
