When Polyethylene is heated in an inert atmosphere and the volatile products are condensed, the molecular weight distribution (MWD) of the product obtained is very wide In addition, this product is very waxy, has poor low properties, and is unusable as a liquid fuel. To improve the product quality, various catalysts are usually used in the recycling process However, these catalysts are costly. On the other hand, if the higher boiling fractions of the volatiles evolved due to degradation are not allowed to escape, then the MWD of the final product can be improved. This paper we have studied pyrolysis of High Density Polyethylene (HDPE) by using a reflux-condenser apparatus at 450℃ for removing of waxes in the pyrolysis oil. The product oil was analyzed by using GC/MS. The analysis result indicates that HDPE waste plastic to produced heavy fuel hydrocarbon chain range C_5 to C_<21> and light gas are also present and hydrocarbon range is Q_1-C_4.
