PP-I-39METHANOL OXIDATIVE STEAM REFORMING FOR HYDROGENPRODUCTION OVER Cu – Au / ZnAl 2 O 4 CATALYSTSMierczynski P., Maniecki T.P., Rynkowski J.M., Bawola-Olczak K., Jozwiak W.K.Technical University of Lodz Institute of General and Ecological ChemistryZeromskiego 116, 90-924, Lodz, PolandHydrogen production is one of the most important raw material for ammoniasynthesis, synthetic gasoline production and many others. During last yearshydrogen was successfully applied as a fuel for fuel cells used in mobile devices(mobile phones, laptops etc). Industrially hydrogen is produced via gasification ofbiomass or natural oil. Unfortunately such processes cannot be applied in smallmobile devices. An interesting opportunity seems to be oxidative methanol reforming(OSR). Those reactions took place in temperature range (150-350°C) and underatmospheric pressure.CH 3 OH + 0,5O 2 -> CO 2 + 2H 2 ΔH= -192,2 KJ/mol (1)CH 3 OH + H 2 O -> CO 2 + 3H 2 ΔH= 49,7 KJ/mol (2)Combination of both reactions (1 and 2) allows to run this reaction as autothermalprocess.CH 3 OH + 0,25 O 2 + 0,5 H 2 O ->CO 2 + 2,5 H 2 ΔH= -71,4 KJ/mol (3)The mail goal of this work was the determination of the influence of copperloading and gold promotion on catalytic activity and selectivity of Au - Cu / ZnAl 2 O 4supported catalysts in OSR of methanol.The catalysts were prepared by impregnation method, the meal loading was5 - 60% wt of Cu and 1 - 5% of Au, respectively. Methanol mixed reforming starts at170°C and reaches 100% of CH 3 OH above 300 °C. Selectivity to CO 2 and H 2 wasclose to 100%, only CO as a side product was detected. Copper loading has stronginfluence on methanol conversion degree. The optimum copper content was 20%,such systems reveal highest activity.Gold promotion has no strong influence on the catalytic activity but improveselectivity to H 2 and CO 2 products.291
