This 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. A

time-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. Implications for ongoing exptl. studies are discussed.

Hydrogen Enriched Methane

Abstract:Noble metals of Pd, Pt, Ru and Rh were introduced into the

CuO/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 and

enhanced 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 promoting
