Adsorption enhanced steam reforming of methanol for hydrogen generation in conjunction with fuel cell: Process design and reactor dynamicsBy: Li, Mingheng; Duraiswamy, K.; Knobbe, MackChemical Engineering ScienceVolume 67, Issue 1, 1 January 2012, Pages 26–33Dynamics, Control and Optimization of Energy S ystemsThis work focuses on a preliminary investigation of hydrogen generation using adsorption enhanced reforming (AER) of methanol in packed-bed reactors. A process design of AER in conjunction wi t h proton exchange membrane fuel cell (PEMFC) is conducted using Honeywell UniSim Design software. Atime-dependent model based on detailed reaction kinetics from the literature is developed to describe the reactor dynamics during both reforming and regeneration steps. It is shown that AER of methanol has a potential to efficiently generate hydrogen in portable fuel cell applications.

Effect of noble metal on oxidative steam reforming of methanol over CuO/ZnO/Al2O3 catalystsCheng-Chun Chang a, Che-Chuan Hsu a, Ching-Tu Chang b, Yu-Pei Chen b, Biing-Jye Liaw c, , , Yin-Zu Chen a, ,International Journal of Hydrogen EnergyVolume 37, Issue 15, August 2012, Pages 11176–11184Hydrogen Enriched MethaneAbstract:Noble metals of Pd, Pt, Ru and Rh were introduced into theCuO/ZnO/Al2O3(30/60/10) catalyst via incipient impregnation and co-precipitation methods to examine their effects on the oxidative steam reforming of methanol (OSRM). No obvious effect of Pd and even a negative effect of Pt were observed by incipient impregnation method. With co-precipitation, noble metals were homogeneously dispersed in CuO/ZnO/Al2O3(30/60/10) and interacted with CuO and ZnO. They improved the reducibility of the catalysts andenhanced the dissociative adsorption of methanol. Introducing Pd, Rh or Ru promoted the conversion of methanol, but enhanced the formation of CO. Depositing platinum exhibited a high conversion of methanol and a low selectivity of CO in the OSRM reaction. The promotingeffect of noble metals involved facilitating the split and adsorption of H atoms during the dehydrogenation of the intermediates in OSRM.钯，铂等贵金属Ru和Rh，引入了CuO／ZnO／Al2O3（30 / 60 / 10）通过浸渍法和共沉淀方法检测对甲醇氧化重整制氢催化剂（反应）的影响。

通过浸渍的方法没有观察到PD效果明显，甚至是负的Pt。

用共沉淀，贵金属均匀地分散在CuO／ZnO／Al2O3（30／60／10）和CuO和ZnO的相互作用。

他们改进了催化剂的还原性和增强的甲醇解离吸附。

介绍了钯，铑或钌促进甲醇的转化率，但提高沉积铂表现出有限的甲醇的高转化率和CO在OSRM反应的低选择性的形成。

贵金属的促进作用参与促进分裂与H原子吸附在反应中的中间体脱氢。
