摘要
The steam reforming of methane was studied over microstructured platelets coated with catalysts and assembled as microreactors. Three different bonding procedures have been applied to assemble the microchannel platelets. The effect of the assembly procedure on the catalytic performance has been investigated for both nickel and rhodium based catalysts. The brazing technology leads, contrary to laser welding, to fully connected platelets resulting in a superior catalytic activity due to better heat transfer and gas flow distribution. Outstanding performances in term on hydrogen productivity and catalytic stability are obtained on the low temperature brazed system washcoated with a Rh-alumina catalyst.
