Latest Patents

One of Matsukawa's latest patents is a method and apparatus for reclaiming oil from waste plastic. This invention addresses the challenges posed by thermosetting resins and solid foreign matter in plastics. The method significantly reduces the need for presorting garbage or industrial waste. To reclaim oil from waste plastic containing chlorine compounds, such as vinyl chloride, the plastic is first stripped of chlorine. The process involves mixing the plastic with heated sand and/or an additive agent to raise its temperature to between 250-350°C. This results in a product that consists of a mixture of sand and substantially dechlorinated plastic. The product is then heated to a temperature of 350-500°C until pyrolysis occurs. A first gas/liquid separation process is employed to separate the pyrolysis product into liquid high-boiling point oil, gaseous low-boiling point oil, and low molecular-weight gases. The liquid high-boiling point oil is recirculated back into the pyrolysis process, while a second gas/liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases.
