Abstract
To optimize shape of reformer in case of the effect of heat conduction of catalyst on characteristics of methanol steam reforning (STR) using Cu-based catalyst is discussed numerically. The cylindrical tube reformer is considered amount of catalyst, mass flow rate, wall temperature were kept. The results are arranged by packing ratio and aspect ratio that means the thickness of catalyst bed while focusing temperature profile in the reformer and reformed gas component nearby output. As a result, if the catalyst bed is heated constantly, the packing ratio does not affect the reforming. When the aspect ratio is increased, H_2 moler fraction in reformed gas decreases while methanol moler fraction increases. Larger Aspect ratio causes lesser reactivity by increasing low temperature around the center of catalyst bed and increasing amount of non-reactant that does not touch the catalyst.
