Enhancing the low temperature water–gas shift reaction through a hybrid sorption-enhanced membrane reactor for high-purity hydrogen production

A Hybrid Adsorbent-membrane Reactor (hamr) System for Hydrogen Production

Introduction An experimental study on the performance of a novel reactor system, termed the hybrid adsorbent-membrane reactor (HAMR) is described here. In the HAMR the reaction and membrane separation steps are coupled with adsorption. It was shown previously by our group that for esterification reactions this results in significantly improved performance. The focus in this presentation is on t...

Advances on High Temperature Pd-Based Membranes and Membrane Reactors for Hydrogen Purifcation and Production

Membrane technology applied in the chemical and energy industry has the potential to overcome many drawbacks of conventional technologies such as the need of large volume plants and large CO2 emissions. Recently, it has been reported that this technology might become more competitive...

Synthesis of a Multilayer Ceramic Membrane Used for Hydrogen Separation at High Temperature

A multilayer composite ceramic membrane was prepared by depositing a nano-scale layer of SiO2 on top of a modified porous alumina support by chemical vapor deposition (CVD) method. The modification of the support was carried out by adding a graded layer of Al2O3 (γ-alumina phase), using sol-gel method. An optimized temperature of 700 K for intermediate layer calcination was gained by XRD analys...

Production of fuel - cell grade hydrogen by sorption enhanced water gas shift reaction using Pd / Ni - Co catalyst

It has been demonstrated both thermodynamically and experimentally that fuel-cell grade hydrogen can be produced by a one-step sorption enhanced water gas shift (SEWGS) process at about 500 oC, where the water gas shift (WGS) catalyst and the CO2 sorbent are highly integrated. A synthetic CaO-based mixed oxide sorbent was also assessed, which showed a good CO2 capture capacity and stability in ...
