۹Abstract The aim of this work is to analyze the potential application of micro porous silica membranereactor carrying out methanol steam reforming reaction for hydrogen production As a furtherstudy a comparison with dense Pd Ag membrane reactor and a traditional reactor working at thesame operating conditions of silica membrane reactor is realized To this purpose and as a firstapproach a one dimensional non isothermal and unsteady state numerical model was developedand its validation was realized by comparing the theoretical results with experimental data In allthree cases a good agreement between modeling results and experimental data was found So themodel was used for studying the effect of some important operating parameters such as temperatureand pressure on the performance of silica membrane reactor in terms of methanol conversion andhydrogen recovery The same study was performed for both dense Pd Ag membrane and traditionalreactors The modeling analyses showed that the membrane reactors present comparableperformance to the traditional reactor in any operating condition Moreover due to higherhydrogen permeability the dense Pd Ag membrane reactor showed a higher performance incomparison to the silica membrane reactor Furthermore the conversion of methanol and the molefraction of each component were measured in different places at various points in time Keywords Hydrogen production Methanol steam reforming Modeling Membrane reactor
