Abstract

Fuel cell as a clean and efficient source of electrical power, which requires hydrogen-rich feed gas as fuel has led to the study of efficient and economical hydrogen production. This article presents the study of the effect of catalyst metal loading and temperature in the reduction of carbon monoxide concentration on hydrogen production by steam reforming of methanol. Experiments were conducted at various reaction temperature (225, 250, and 275 deg C), and three types of catalyst (Cu10-V2.5, Cu9.4-Ni11.3, and Ni12.5-Mo5.05) according to Taguchi method design of experiment, using a standard orthogonal array L9(34). The effects of reaction temperature and catalyst on the reduction of carbon monoxide concentration in hydrogen production by steam reforming of methanol were evaluated using Taguchi optimization methodology by utilizing the signal-to-noise (S/N) ratio and Pareto analysis of variance (ANOVA). The analysis of the result shows that the optimal combination for low concentration of CO is at level 2 (Ni12.5-Mo5.05) of catalyst, and level 0 (225 deg C) of temperature. Pareto ANOVA analysis shows that the catalyst effects contribute about 62% on the reduction of CO concentration followed by reaction temperature of 38%. The Taguchi method design of experiment is found suitable to be applied for optimization process in this study.
