Outline of Final Research Achievements

Passive production of synthetic gas from liquid methanol using a packed bed of porous material particles supporting catalyst has been investigated. Heating of the upper portion of a vertical tube in which the porous particles are packed and the bottom is dipped to liquid methanol causes steady, upward fluid flow due to capillary action enhanced by evaporation. The synthetic gas is produced due to the catalytic reaction in the dried region and then flows out of the top end of the tube. The length of the dried region is compared with the prediction of the theoretical model. The reaction yield and energy utilization efficiency are examined. The effectiveness of the proposed passive reactor has been confirmed.
