Description
Summary:Biomass derivatives are very promising as one renewable energy source to overcome the limited fossil fuel reserves. Bioethanol is one of the renewable energy resources from the second-generation feedstock that is attractive for further research. Besides, ethanol is also widely used in various applications as a solvent, chemical commodity, cosmetic and pharmaceutical industries, and others. Ethanol can be produced by the hydrogenation of acetic acid. In this work, the focus is on the supported nickel and copper-based as non-noble metallic catalysts to replace the precious metals such as Pt, Pd, and Ru. The nickel and copper-based catalysts were prepared to carry out the hydrogenation of acetic acid to enable ethanol formation. The catalysts were characterized by XRD, N2 physisorption, and TPD-NH3. The catalyst activity was investigated through hydrogenation of acetic acid solution in a batch reactor at 250 °C, 120 bar, for 18h. The highest ethanol yield was obtained at 64.52 mol% by Ni-In/TiO2 catalyst.
