Quasicrystalline Catalyst for Steam-Reforming of Methanol
MRS Proceedings, 2000AbstractSteam reforming of methanol (CH3OH + H2O -> 3H2 + CO2) has been performed on a number of Al-Cu-based stable quasicrystals and related alloys. Alloys leached in NaOH aqueous solution exhibit the highest activity for steam-reforming of methanol. Among the alloys, AlCuFe quasicrystal, after leaching treatment, reveals excellent activity.

Integrated Methanol Steam Reformer/Electrochemical Hydrogen Compressor
ECS Transactions, 2013An electrochemical hydrogen compressor (EHC) based on a solid acid electrolyte is built. The EHC operates at temperatures from 230 to 250 °C. The EHC can be used to separate hydrogen from simulated reformate containing more than 2 % CO. The EHC can be directly combined with a methanol steam reformer (MSR).

Controlling ZnO morphology for improved methanol steam reforming reactivity
Physical Chemistry Chemical Physics, 2008The selectivity towards CO2 during steam reforming of methanol on Pd increases in the order Al2O3 < ZrO2 < ZnO. However, conventional catalyst preparation can damage the ZnO surface, even causing complete dissolution. The faceted, prismatic ZnO crystals in the support (Aldrich) get easily destroyed during catalyst preparation. We show in this work that,

Methanol steam reforming over ex-hydrotalcite Cu–Zn–Al catalysts
Applied Catalysis A: General, 2006Cu-ZnO-Al2O3 catalysts have been prepared via hydrotalcite-like hydroxycarbonate precursors and tested in the oxidative steam reforming of methanol (MOSR) to produce hydrogen with poor CO content. The surface chemistry of the catalysts has been investigated by IR spectroscopy of low temperature CO adsorption.

Steam reforming of methanol using supported Mo2C catalysts
Applied Catalysis A: General, 2007Abstract Two supported molybdenum carbide catalysts, Mo2C supported on γ-alumina (Mo2C/γ-Al2O3) and zirconia (Mo2C/ZrO2), were investigated as an alternative catalyst for steam reforming of methanol. The catalysts were prepared by a temperature-programmed reaction (TPR) method, and it was found that the supported Mo2C catalysts are superior to an ...

Development of Methanol Steam Reformer for Chemical Recuperation
Journal of Engineering for Gas Turbines and Power, 2000The purpose of the present work is to establish the design method of methanol steam-reformer for application to chemical recuperation in a gas turbine system. The reaction rate of the methanol steam-reforming was measured with a small amount of catalyst using the gaseous mixture of methanol, water, hydrogen, and carbon dioxide as a simulated product ...

Steam Reforming of Methanol Over Pd-Zn Catalysts
Reaction Kinetics and Catalysis Letters, 2000Heating the physical mixtures of Pd and Zn selectively yielded PdZn or Pd3.9Zn6.1 alloy. These alloys were highly selective for the steam reforming of methanol.

Microwave-activated methanol steam reforming for hydrogen production
International Journal of Hydrogen Energy, 2011Abstract Methanol steam reforming (MSR) was carried out in a catalytic packed bed reactor under electrical and microwave heating using the two most common catalysts for this process–CuZnO/Al 2 O 3 and PdZnO/Al 2 O 3 . Significant two-dimensional temperature gradients were found, especially in the latter case.
