Production of high-purity hydrogen by sorption-enhanced steam reforming process of methanol

Hydrogen production by sorption-enhanced steam reforming of glycerol.

Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...

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...

Multifunctional Pd/Ni-Co Catalyst for Hydrogen Production by Chemical Looping Coupled Sorption Enhanced Steam Reforming of Acetic Acid

High yield of H2 of high purity from acetic acid, a model compound of bio-oil from the biomass fast pyrolysis, was produced by sorption enhanced steam reforming (SESR). An oxygen carrier was introduced into a chemical loop (CL) coupled to the cyclical SESR process to supply heat in situ for the endothermic sorbent regeneration, in order to increase the energy efficiency of the process. A new mu...

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...
