Synthesis of metal nano-oxides from Al, Mg and Ni nitrates via sol-gel method used for hydrogen production via methane reforming

Hydrogen production from cleaner ways should be taken in to account to develop hydrogen-based fuel cells and infrastructure technologies. The present research deals with catalyst development for dry reforming of methane with the aim of reaching highest yield of the main product H2 which can be utilized in full cells. The catalyst was prepared via sol-gel method and characterized with XRD, FESEM, FTIR and BET techniques. XRD patterns reveal high dispersion of active metal and FESEM images indicate uniform particle size distribution. It has been found that using sol-gel method has the potential to improve catalyst desired properties resulting in catalytic performance enhancement. The reforming reactions were carried out using constant feed ratio and gas hourly space velocity (GHSV) at different reaction temperatures to indentify the influence of reaction temperature. The highest yield for H2 was obtained at 850°C. Also effect of different GHSVs on the catalyst activity was studied. The stability test was conducted for 10h maintaining at constant temperature, molar feed ratio and GHSV.
