Catalytic Microreactors for Portable Power Generation Catalytic Microreactors for Portable Power Generation addresses a problem of high relevance and increased complexity in energy technology. This thesis outlines an investigation into catalytic and gas phase combustion characteristics in channel flow platinum coated microreactors. The emphasis of the study is on microreactor microturbine concepts for portable power generation and the fuels of interest are methane and propane. The author carefully describes numerical and experimental techniques providing a new insight into the complex interactions between chemical kinetics and molecular transport processes as well as giving the first detailed report of hetero homogeneous chemical reaction mechanisms for catalytic propane combustion. The outcome of this work will be widely applied to the industrial design of micro and mesoscale combustors.
