Microstructured plate heat exchanger reactors for high temperature applications

Microchannel reactors and heat exchangers have been developed by application of a novel laser welding technique, which generates durable sealing of the reactors for operating temperatures up to 1000 °C. A microreactor for exhaust gas cleaning purposes has been operated for 35 000 h in a laboratory environment. Results from the operation of a diesel oxidative steam reformer in combination with a hot gas driven evaporator are presented.
