heal.abstract	This paper presents a detailed study of post-consumer polymers coliquefaction with lignite assessing the feasibility of the new processes. The results of four series coprocessing experiments undertaken with and without catalysts on a suite of four heavy organic solvents are summarized initially. Taking into consideration the prescribed findings two newer series of experiments were also designed and carried out aiming at the optimization of this complex transformation using this time lignite oxidatively pretreated. The conversion of reacting solids into gaseous and liquid products and in particular into hexane and tetrahydrofuran (THF) soluble material was determined. It was found that the mentioned hydroliquefaction is a promising way of hydrocarbon synthesis and that oxidatively pretreated lignite proved more effective than the raw material since it promoted coliquefaction product yields sufficiently. It was also found that interactions and synergy of the catalysts employed was changing as a function of the solvents nature, influencing thus the efficacy of the conversions achieved.
