4. Conclusions
The present study aims to provide an improved methanol steam reformer reactor system and process for the carrying out of vapor phase heterogeneous reactions. The effect of temperature on the methanol mole fraction and effective factor is investigated for a microchannel methanol steam reformer with different shapes of the cross section of the process microchannel. Particular emphasis is placed upon the heat and mass characteristics involved in vapor phase heterogeneous reaction processes in methanol steam reformers. The major conclusions are summarized as follows:
