The use of asymmetric ceramic hollow fibres as a support of either catalysts, selective membranes or both catalyst and selective membrane at the same time, is the key step for an economical, large scale and effective H2 productioni. Nowadays, H2 is not only widely used in industrial processes, but also it is growing the interest of using it as an energy vector in the scientific communityii. However, today, 96% of the total global H2 production (45 million tons per year) comes from steam reforming of fossil fuels which is an endothermic and thermodynamic equilibrium limited process. Moreover, steam reforming of fossil fuels involves several stages such as production and purification, and produces a certain amount of COX, which has a greenhouse gas effect and it must be captured. The use of enhance reactors such as catalytic hollow fibre micro reactor (CHFmR) and catalytic hollow fibre membrane reactor (CHFMR) allow the intensification of the whole process.In this context, methanol is a promising renewable source of H2 since it can be easily decomposed in the presence of H2O to produce H2: CH3OH+ H2O→ CO2+ 3H2 (∆ Hº=+ 49.4 kJ/mol). In addition, the CO2 produced during the methanol steam reforming (MSR) reaction is consumed by biomass growth which nearly closes the carbon loop. The chemical-physical properties of methanol, ie liquid at room temperature and atmospheric pressure, make it possible to be used as a “storage-molecule” of H2 for on-board applicationsiii.
