  • Patent number: 11618854
    Abstract: A process for converting waste plastic into oil includes: subjecting the waste plastic to be in contact with a plurality of far-infrared ray heating rods in a reactor which contains an agitator configured to distribute the waste plastic; converting the waste plastic into a liquid form resultant decomposition by thermal decomposition and pyrolysis in the reactor; fractionating the resultant decomposition product to obtain gas, light oil, and crude diesel oil; obtaining a sludge from a bottom portion of the reactor and transferring the sludge to a blending tank; transferring the light oil to the blending tank; mixing the sludge and the light oil using a high-speed shearing machine to produce a sludge and light oil mixture; transferring the sludge and light oil mixture to a homogenizer; and blending the sludge and light oil mixture at the homogenizer to form a blended oil.
