THERMAL DE-POLYMERIZATION PROCESS OF PLASTIC WASTE MATERIALS

摘要

The present invention relates to a process for producing liquid transportation fuel (15) based on plastic waste materials (10), comprising the step of: providing (S101) plastic waste materials (10) in molten form; de-polymerizing (S103) molten plastic waste materials (10) into a reaction chamber using a limestone catalyst (20) at a temperature ranging 420° C. to 450° C. under normal atmospheric pressure condition of 1 Bar; and introducing (S106) gaseous de-polymerized products (25) to a distillation unit thereby allows the gaseous de-polymerized products (25) to be fractionally distilled and condensed into liquid transportation fuels (15).
