| Abstract | ||||
| Plastic waste is one of the serious problems that comprehend a negatively impact on the environment. The objective of the current work is to develop a process for converting some disposals such as wastes of polyethylene (WPE), polypropylene (WPP) and polystyrene (WPS), mixed with used lubricating oil (ULO) as carrier media, to more valuable products. This technique is currently put into practice under atmospheric pressure, using lignin, as a catalyst. The results demonstrated that the largest magnitude of gasoline can be attained from the dissociated WPS/ULO product, as it constitutes approximately 90 wt.% of the cracked sample, On the other hand, 52.3 wt.% of the prepared gasoline-like is available in the liquefied WPP/ULO, whereas the least quantity of this fraction (42.3 wt.%) is accessible in the degraded WPE/ULO. The distillates analogous to kerosene, the recorded data reveal that this fraction attained from the degraded WPP/ULO and WPE/ULO is approximately similar in amounts, comprising about 26-25 wt.%.On contrast, the product received from WPS/ULO cracking is characterized by the scarcity of this cut, as it represents 2.6 wt.% from the yield .the constituents of the heavier fraction petroleum gas oil the quantities of these components are equal to 16.6 and 20.8wt.% for degraded WPP/ULO and WPE/ULO, successively, whereas the lowest value of 7.4 wt.% was derived from the cracked WPS/ULO. | ||||
