Cost Optimization of H2 Production by Methanol Steam Reforming over Anodized Aluminum Oxide

Abstract

In this work, preparation conditions of AAO with regular pores and uniform thickness has been optimized. The two types of AAO, AAO as synthesized and hydrated AAO (by HWT) were prepared and impregnated with Cu and Zn. The surface morphology and Cu content were analyzed by FE-SEM and EDAX measurements. The difference in BET surface area and its effect on Cu impregnation has also been discussed. The activity of the catalysts for methanol conversion was tested and the Cu-AAO catalysts prepared by dipping method several times showed promising result (73%) with 100% selectivity towards H2. Addition of Zn further increased the conversion to 97%.
