520 |a This work is a preliminary study for the development of a co-pyrolysis process of plastic wastes excavated from a landfill and used lubrication oils, with the aim to produce an alternative liquid fuel for industrial use. First, thermogravimetric experiments were carried out with pure plastics (HDPE, LDPE, PP and PS) and oils (a motor oil and a mixture of used lubrication oils) in order to highlight the interactions occurring between a plastic and an oil during their co-pyrolysis. It appears that the main decomposition event of each component takes place at higher temperatures when the components are mixed than when they are alone, possibly because the two components stabilize each other during their co-pyrolysis. These interactions depend on the nature of the plastic and the oil. In addition, co-pyrolysis experiments were led in a lab-scale reactor using a mixture of excavated plastic wastes and used lubrication oils. On the one hand, the influence of some key operating parameters on the outcome of the process was analyzed. It was possible to produce an alternative fuel for industrial use whose viscosity is lower than 1Pas at 90°C, from a plastic/oil mixture with an initial plastic mass fraction between 40% and 60%, by proceeding at a maximum temperature included in the range 350-400°C. On the other hand, the amount of energy required to successfully co-pyrolyze, in lab conditions, 1kg of plastic/oil mixture with an initial plastic mass fraction of 60% was estimated at about 8MJ. That amount of energy is largely used for the thermal cracking of the molecules. It is also shown that, per kg of mixture introduced in the lab reactor, 29MJ can be recovered from the combustion of the liquid resulting from the co-pyrolysis. Hence, this co-pyrolysis process could be economically viable, provided heat losses are addressed carefully when designing an industrial reactor
