✦ Synopsis

Mechanical degradation of the solid particles used in sorption-enhanced steam methane reforming (SE-SMR) was investigated in a gas jet attrition apparatus. The performance of a dolomite, a limestone and a commercial reforming catalyst were compared based on the air jet attrition index (AJI). The dolomite showed the poorest resistance to attrition, likely due to the extra pore volume caused by calcination of MgCO 3 . The degree of loss of fines from the catalyst was significant, pointing to the need to develop catalysts suited to fluidized bed operation. Co-fluidization of the harder catalyst and the dolomite did not lead to additional attrition of the dolomite.

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
