Abstract:
1. A method for thermolysis of waste plastics in presence of an inert gas, the method comprising: feeding waste plastics from a feeding system to an extruder; plasticizing the waste plastic at a temperature of 180° C. producing molten plastic waste; feeding the molten plastic waste to a thermolysis reactor operating at a temperature between 350° C.-450° C.; stirring the molten plastic waste at a speed between 30-1500 rpm; discharging the waste continuously into a thermo separation column; and condensing the waste in the thermo separation column into fraction products; wherein a light fraction is discharged to a first storage tank and boiled to 180° C. and a heavy fraction is discharged to a second storage tank and boiled above 180° C.
