Through the experiments of a demonstration plant with waste plastic feeding capacity of 5 tons per day, a chemical recycle process of waste plastic has been established. Waste plastic including polyvinyl chloride was partially oxidized by oxygen and steam to produce synthetic gas (syngas), mainly composed of CO and H_2, by using an entrained single stage reactor at the pressurized condition and from this syngas methanol was synthesized by means of liquid phase catalytic process. C conversion and cold gas efficiency of this entrained gasifier were attained 96 percent and 63 percent, respectively. Methanol purity synthesized by liquid phase method reached more than 98 percent. Long-duration experiment proved a reliability of this process and encouraged us toward commercialization.
