METHANOL STEAM REFORMING FOR HYDROGEN PRODUCTION IN MICROCHANNEL REACTORS

نویسندگان

چکیده

Many attempts have been made to improve heat transfer for thermally integrated microchannel reforming reactors. However, the mechanisms effects of design factors on characteristics are still not fully understood. This study relates a thermochemical process producing hydrogen by catalytic endothermic reaction methanol with steam in reactor. Computational fluid dynamics simulations conducted better understand consumption, generation, and exchange thermal energy between exothermic processes The wall conduction properties channel dimensions reactor performance investigated. Thermodynamic analysis is performed based specific enthalpy evolution results indicate that conductivity walls fundamentally important. Materials high preferred walls. Thermally conductive ceramics metals well-suited. Wall materials poor degrade performance. Reaction flux profiles considerably affected dimensions. peak increases while maintaining flow rates. change positive negative reaction. sensible always positive. Design recommendations

Effect of Pt on Zn-Free Cu-Al Catalysts for Methanol Steam Reforming to Produce Hydrogen

Steam reforming of methanol can be considered as an attractive reaction aiming at hydrogen production for PEM fuel cells. Although Cu/Al-contained catalysts are considerably evaluated in this reaction, further evaluation is essential to evaluate the impact of some promoters like Pt in order to find a comprehensively optimized catalyst. Pt promoter is employed with different methods in this ...

Hydrogen Production by Methanol Steam Reforming on Copper Boosted by Zinc–Assisted Water Activation**

For use of polymer electrolyte membrane fuel cells (PEMFC) in mobile power applications, an efficient source of COdepleted hydrogen is needed. To avoid technical and safety problems of hydrogen handling, storage, and transport, methanol can be used as practical and abundant energy carrier for on-board H2 generation, as it has the advantage of a high energy density. Hydrogen generation from meth...

High yields of hydrogen production from methanol steam reforming with a cross-U type reactor

This paper presents a numerical and experimental study on the performance of a methanol steam reformer integrated with a hydrogen/air combustion reactor for hydrogen production. A CFD-based 3D model with mass and momentum transport and temperature characteristics is established. The simulation results show that better performance is achieved in the cross-U type reactor compared to either a tubu...
