ABSTRACT

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, supporting method of the alumite catalysts was studied to increase the durability of the catalysts and prevent carbon formation. The durability of the CO₂ absorption agent was also studied to improve the using times and prevent abrasion phenomenon. Then, the amount of hydrogen that was needed to feed in the 1kW class of household fuel cell was assumed. From this condition, required catalysts and CO₂ absorbent were computed. After that, the box reactor was designed in order to introduce these plates adequately and calculation of the reactor volume was carried out.

Keywords: Ethanol, Non-equilibrium system, CO₂ absorbent.
