The dielectric refinement of the oil extracted from the kernel of the phyllanthus emblica

The analysis of constituent and physicochemical characteristics indicates that the oil extracted from the kernel of the phyllanthus emblica has the potential to be transformed to high - quality oil, for example biological aircraft fuel A set of dielectrical - refined machines is optimized to purify the oil extracted from the kernel of the phyllanthus emblica. The oil extracted from the kernel of the phyllanthus emblica is refined by dielectric refinement by BaTiO3 as the dielectric, and the parameters were set as dielectrical constant εp = 14 000 F · m^-1 , the separation voltage U = 7 000 V, the velocity v = 60 mL · min^-1. The impurities of the oil decreased dramatically, with mercaptan to be purified to 97% and naphthenic acid to more than 65.5%. Due to its simplicity, controllability and no chemical substances usage, this manufacture procedure is environment friendly refinement process, which provides key technology to translating the Kernel of the Phyllanthus Emblica to the biological aircraft oil and other high-quality oils. Besides, this process broadens the new application of materials of high dielectric constant.
