For methanol steam reforming process in a micro-channel reactor

a steady-state multi-component three-dimension transport-reaction model was established.The catalytic process over Zn_Cr/CeO2/ZrO2 taken place in rectangular parallel micro-channels and in comby fractal micro-channel network was simulated numerically

and the effect of operating condition on reaction performance was investigated. The results indicated that the use of these micro-channels can make methanol conversion and hydrogen yield increase.Meanwhile

compared with rectangular parallel micro-channels

comby micro-channel network is of several advantages:much smaller requirement for pump power

adsorbing more heat under the same heating area and producing more uniform distribution of temperature.So

methanol conversion can be enhanced and CO reduced

which improve quality of hydrogen production.
