“…Hwang et al [16] studied the reaction over a silicon-based microreactor coated with a Pt/Al 2 O 3 catalyst, yielding 99.4% CO conversion. Kim et al [15,17] obtained CO outlet concentration below 50 ppm at O 2 /CO ratio of 2.5 by using a 13-layered microchannel reactor built by stacking chemically etched stainless steel plates coated with a Pt-Co/Al 2 O 3 catalyst. Despite most of the work on CO-PROX in microreactors has been carried out using noble metal based catalysts a few insights on copper based catalysts have been reported.…”

The different steps for manufacturing a microchannel reactor for the PROX reaction are discussed. Transient Liquid Phase bonding (TLP) using a Ni-B-Si amorphous melt spun is used for joining micromilled Al-alloyed ferritic stainless steel plates followed by recrystallization at 1200ºC for 5 hours. A CuO x -CeO 2 catalyst synthesized by the coprecipitation method was washcoated on the microchannel block resulting in a homogenous 20-30 µm thick layer. The catalytic activity for CO-PROX reaction is similar in both the powder catalyst and the microchannel coated reactor but the selectivity is higher in the microchannel reactor. Keywords

“…Reasonable microchannel structure can effectively improve the velocity uniformity among parallel microchannels, which leads to uniform residence time distribution among microchannels and hence improves the conversion rate and selectivity of process [10][11][12]. Parallel and uniform-distributed microchannels with rectangular cross-section were generally adopted in a majority of researches [13][14][15]. However, it is unknown whether this microchannel structure is the best choice.…”
