Catalytic Membrane Reactor for Extraction of Hydrogen from Bioethanol Reforming
This research explores a novel application of catalytic membrane reactors for high- purity hydrogen extraction from bioethanol reforming. Conventional membrane systems employ hydrogen permselective materials such as palladium, polymer membranes, which present several material challenges including …

Direct synthesis gas conversion to alcohols and hydrocarbons using a catalytic membrane reactor.
In this work, inorganic membranes with highly dispersed metallic catalysts on macroporous titania-washcoated alumina supports were produced, characterized and tested in a catalytic membrane reactor. The reactor, operated as a contactor in the forced pore-flow-through mode, was used for the …

Development and testing of inorganic membranes for hydrogen separation and purification in a catalytic membrane reactor.
Palladium membranes have been identified as the membranes of choice in hydrogen separation and purification processes due to their infinite selectivity to hydrogen when defect-free. Despite their potentials in hydrogen processes, palladium membranes pose challenges in terms of cost and …

Combined Hydrogen and Oxygen transport membranes in the activation of Methane
Dense ceramic membranes have been extensively studied for gas separation and as reaction supports for significant environmental processes. In the work presented in this thesis, yttrium/zirconia doped barium cerate (BaCe0.8Y0.2O3-δ- BCY20 and BaCe0.6Zr0.2Y0.2O3-δ- BCZY) powders were synthesised …

Synthesis and characterization of thermally stable palladium-based composite membranes for high temperature applications
… in electroless-plated palladium-based composite membranes has been revisited. Palladium was doped with a higher melting point element such as ruthenium or platinum and the rate of increase of the nitrogen leak in the temperature range of 500-600 ºC was determined. The results showed that doping …
