Abstract

Low temperature steam reforming of ethanol in the temperature range of 200–360°C was studied to maximize the production of H2. The optimum reaction conditions in presence of a suitable catalyst can produce mainly the desired products H2 and CO2. Cu/Al2O3 catalysts with six different concentrations ranging from 0 to 10 wt.% Mn, were prepared, characterized and studied for the ethanol-steam reforming reaction. Maximum ethanol conversion of 60.7% and hydrogen yield of 3.74 (mol H2 / mol ethanol converted) were observed at 360°C for catalyst with 2.5 wt.% Mn loading.

Abstract

On a étudié le reformage de l'éthanol à la vapeur à basse température dans la gamme de températures de 200-360 ºC afin de maximiser la production de H2. Les conditions de réaction optimales en présence d'un catalyseur adéquat peuvent produire principalement les produits désirés soient H2 et CO2. Des catalyseurs de Cu/Al2O3 à six concentrations différentes variant de 0 à 10 % en masse de Mn, ont été préparés, caractérisés et étudiés pour la réaction de reformage de l'éthanol à la vapeur. Une conversion d'éthanol maximum de 60,7 % et un rendement d'hydrogène de 3,74 (H2 mol/éthanol converti mol) ont été obtenus à 360 ºC pour un catalyseur ayant une charge de Mn de 2,5 % en masse.
