ABSTRACT Ethanol (C2H5OH or EtOH) has lower energy content, adsorbs water and leads to separation and dilution problems in storage tanks and is corrosive to fuel infrastructure. 1-butanol (C4H9OH or 1-BuOH) have fuel properties and is more closely resemble those of gasoline. Therefore, becoming a promising alternative to ethanol as a substitute for fossil fuels, it is essentially non-corrosive, and has an energy density of 90%. Therefore, in this study, it was aimed to produce 1-butanol from the ethanol wastes using copper-nickel-manganese nanocomposites (Cu-Ni-Mn-NCs). Nano Cu and nano-Ni were hydrogenating/dehydrogenating components and manganese oxide (MnO2) has acid/base properties and provides high surface area. The catalysts were characterized by X-ray diffraction (XRD), temperature-programmed reduction (TPR), specific surface area, ammonia (NH3) temperature-programmed desorption (TPD), carbon dioxide (CO2) chemisorption, transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) analyses, respectively. XRD, TEM, XPS analysis showed nanocomposite production followed a Guerbet route and demonstrated good stability and activity. The effects of Cu-Ni-Mn NCs concentrations and pH levels on the production of 1-butanol was studied. The maximum 1-butanol production yield was 96% at an ethanol concentration of 4 mg/l at 2 mg/l Cu-Ni-Mn NCs concentration at a Mn percentage of 18% after 15 min at a pH of 8.02. Cu-Ni-Mn NCs can be used for 1-butanol production from the ethanol producing industry wastes. |
