Microstructured Plate Heat Exchanger Reactors for High Temperature Applications

Abstract

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. Figure 5. Microstructured hot gas driven evaporator.

Microchannel Fuel Processors as a Hydrogen Source for Fuel Cells in Distributed Energy Supply Systems

“…While trucks have diesel fuel readily available, LPG is the right choice for caravans. 35 Idling of truck engines was common practice in the U.S., where drivers spend considerable time in the vehicles overnight. By idling, 1.2 billion gallons of diesel were consumed in the U.S. in 2010.…”

“…In the scope of the European project HYTRAN, a diesel APU was developed that was based on microchannel plate heatexchanger technology. 35 The complete system is shown in Figure 8.…”

“…The choice of fuel converted to hydrogen mainly depends upon the application and existing infrastructure. While trucks have diesel fuel readily available, LPG is the right choice for caravans . Idling of truck engines was common practice in the U.S., where drivers spend considerable time in the vehicles overnight.…”

“…Diesel-fueled APU systems based on fuel cell technology show great potential in terms of reducing detrimental effects on human health and the reduction of the environmental impact, while their huge market potential has been forecasted and the payback period was estimated to exceed no more than 2 years. In the scope of the European project HYTRAN, a diesel APU was developed that was based on microchannel plate heat-exchanger technology . The complete system is shown in Figure .…”
