Hydrogen as a fuel

The specific objectives of this study are: 1. To conduct a literature review on carbon-based hydrogen storage electrodes and direct proton absorbance in various forms of carbon; 2. To prepare and characterise activated carbon samples with proper porosity for the present application; 3. To manufacture and characterise a range of composite materials containing carbon material and a proton-conducting medium such as nafion in various levels of hydration 4. To fabricate a number of membrane-electrode-assembly (MEA) from the composite materials;…

C2H5OH has been using as an alternative fuel for decades; HO2 also plays a pivotal role in the combustion. The kinetics and mechanism for the reaction between C2H5OH and HO2 radical have been investigated using the molecular parameters for the reactants, transition states and products predicted at the CCSD(T)//B3LYP/6-311++G(3df,2p) level of theory.

Abstract A new method is presented for improving the performance of red mud as a hydrogenation catalyst (a residue from the production of alumina by the Bayer process that contains iron oxides), based on the method developed by K.C. Pratt and V. Christoverson, Fuel 61 (1982) 460. The activation method consists essentially in dissolving red mud in a mixture of aqueous hydrochloric and phosphoric acids, boiling the resulting solution, adding aqueous ammonia until pHˆ8, and ®ltering, washing, drying and calcining the resulting precipitate. ...
