Etude du procede de production d’hydrogene par vaporeformage et par vaporeformage autotherme du bio-methanol

Abstract

The fuel cell and hydrogen can be a solution in the development of zero-emission vehicles. Furthermore, because its combustion produces only water, the hydrogen could be considered as the fuel of the future. Among fuels, which may be converted to hydrogen, bio-alcohols, especially methanol, it is easily decomposed in the presence of water and produces a hydrogen-rich mixture suitable for powering a fuel cell. This study presents a mathematical approach describing the behaviour of methanol steam reforming and autothermal steam reforming processes in a Pd membrane reactor. The main results show that we can obtain pure hydrogen with a significant amount. This is the result of the total conversion of the initial charge of methanol via both processes under some optimum operating conditions.
