Development of Membrane Reactors for Dehydrogenating Organic Chemical Hydrides to Supply High-purity Hydrogen

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...

Dealloyed Ruthenium Film Catalysts for Hydrogen Generation from Chemical Hydrides

Thin-film ruthenium (Ru) and copper (Cu) binary alloys have been prepared on a Teflon™ backing layer by cosputtering of the precious and nonprecious metals, respectively. Alloys were then selectively dealloyed by sulfuric acid as an etchant, and their hydrogen generation catalysts performances were evaluated. Sputtering time and power of Cu atoms have been varied in order to tailor the hydrogen...

Membrane reactors: A way to increase efficiency

Production of hydrogen from chemical hydrides via hydrolysis with steam

This is an investigation of a gas/solid chemical reaction between steam and chemical hydrides that liberates pure hydrogen gas. The aim is to obtain fundamental kinetic, chemical, and thermodynamic data on the reaction so that sufficient information is known to evaluate this technology rigorously for its potential as a means of delivering hydrogen for fuel cells and internal combustion engines....

Complex Hydrides for Hydrogen Storage

Complex hydrides, containing a minimum of 7.5 wt% hydrogen, are being investigated as hydrogen storage compounds for automotive use. As a new project, the work to date has largely involved refurbishment of equipment and acquisition of study materials. Initial experiments have confirmed that the instrumentation is functioning and that the data being obtained agree with that in the literature. In...
