In methanol steam reforming, commercial catalysts in the form of pellets are mainly used, but there are limitations to directly apply them to underwater weapon systems that require shock resistance and heat transfer characteristics. In this study, to overcome this problem, a multi-layer cup structure (MLCS) was applied to support a pellet type catalyst. The characteristics of pellet catalyst supported by MLCS and the pellet catalyst supported by conventional structure (CS) were compared by the reforming experiment. In the case of MLCS, a high methanol conversion rate was shown in the temperature range 200 to 300℃ relative to the CS manufactured with the same catalyst weight as MLCS. CS shown similar characteristics to MLCS when it manufactured in the same volume as MLCS by adding an additional 67% of the catalyst. In conclusions, MLCS can not only reduce catalyst usage by improving heat transfer characteristics, but also support pellet catalyst in multiple layers, thus improving shock resistance characteristics.
