With the steady depletion of fossil fuel reserves and the
greenhouse effect of these fuels, the demand for hydrogen is
expected to accelerate since hydrogen is an alternative clean energy source to replace fossil fuels. These factors are creating a continued interest in developing economical and viable methods for hydrogen production and separation. In recent years, the application of high-temperature membrane reactors (e.g. for the catalytic dehydrogenation of hydrocarbons) has received growing attention. It is well known that membranes have the potential to surpass the equilibrium conversion by selective removal of one of the reaction products, usually hydrogen. Palladium (Pd) and Pd membranes have consequently received growing attention for separation and purification of hydrogen, due largely to the unique permselectivity of Pd to hydrogen and good mechanical
In this study, Pd/TiO2 and Pd/Al2O3 composite membranes
were prepared by electroless plating method. Membranes were
characterized by SEM and SEM Analytic Mapping Methods.
Permeation experiments were performed between 573−648 K.
The prepared membranes could be used in the membrane
reactor in order to perform dehydrogenation of
methylcyclohexane reaction which was investigated in a fixed
bed catalytic reactor previously. Then the performances of the reactors could also be compared.
