The main objective of the present study was to investigate pyrolysis of oil shale with polyethylene, in terms of yields and properties of the products obtained. A detailed characterization of gas, oil and char from copyrolysis is presented. Although no synergetic effect on the product yield was observed during the copyrolysis, the addition of polyethylene (PE) to oil shale improved fuel properties of shale oil leading to a decrease in the oxygen content of shale oil. As the ratio of polyethylene increased in the blends, the amount of aliphatic compounds in tars increased while that of polar compounds decreased. In addition, the presence of PE in the blend improved the composition of pyrolysis gas leading to an increase in combustible gases. The production of activated carbon from char obtained from oil shale/polyethylene (1/1) was also carried out. Although the surface area of activated carbon was smaller than that of obtained from lignocellulosic materials, it had a notable adsorption capacity for Cr(VI) (55.25 mg/g).
