The aim of this research is to investigate a hydrogen production system using low concentration of ethanol derived from biomass fermentation-renewable materials. By using a non-equilibrium box reactor containing CO2 absorption agent and alumite catalyst in plate type, CO2 and CO can be removed from the reaction field, without CO converting and dividing reactors. Due to insertion of CO2 absorbent, it helped to build up hydrogen selectivity and decrease carbon monoxide formation. First, the support method of the alumite catalysts is studied to increase the durability of the catalysts and prevent carbon formation. The durability of the CO2 absorption agent is also studied to improve the use times and prevent abrasion phenomenon. Then, the amount of hydrogen that is needed to feed in the 1 kW class household fuel cell is assumed. From these conditions, the required catalysts and CO2 absorbent are computed. Subsequently, a box reactor is designed in order to appropriately introduce these plates, from which calculation of the reactor volume is performed.
