Latest Patents
Nobusawa's latest patents include a method for treating plastics and a method for refining methylnaphthalene-containing oil. The first patent describes a method for treating plastics that allows for the simultaneous dehydrochlorination of plastics containing mixed films. This innovative approach involves mixing the plastics with an organic solvent at a temperature not lower than 150°C, allowing the plastics to dissolve and/or swell, and subsequently removing the organic solvent. The resulting product can be solidified to produce solid fuels and reducing agents for ores. The second patent focuses on refining methylnaphthalene-containing oil through azeotropic distillation with ethylene glycol, which reduces nitrogen compounds in the methylnaphthalene fraction. This fraction is then hydrodesulfurized in the presence of a catalyst containing molybdenum, cobalt, or nickel.
