Methanol steam reforming in supported Pd

Methanol steam reforming in supported Pd membrane reactor The supported Pd membrane is promising for the production of high-purity hydrogen from catalytic steam reforming of methanol. At the 35°C reaction temperature, the catalyst activity and stability are promoted by increasing the alumina content. Here a compact doublejacketed reactor has generated high-purity hydrogen directly from steam reforming of methanol, with no need for external purification and a much higher recovery yield.

environments was investigated. The corrosion rate is higher under 'outlet' conditions at 700°C compared to standard conditions at 650°C and 'inlet' conditions at 600°C. The corrosion potential increases with time when a protective corrosion layer is formed. Eventually it reaches a more positive pote
