The present research seeks to study the quality of the pyrolytic liquids obtained from the catalytic pyrolysis of plastic waste. Samples obtained at four temperature conditions -550 ° C, 600 ° C, 650 ° C and 700 ° C - and three were analyzed With the catalyst / plastic residue ratio conditions -0, 10 and 20% -, the following physicochemical properties were evaluated: pour point (ASTM D97), kinematic viscosity (ASTM D445) and Pensky Martens flash point (ASTM D93). The results obtained show that the higher the catalyst / plastic residue ratio, the lower the pour point. Regarding the viscosity, the higher catalyst / plastic residue ratio and for the same temperature, the viscosity decreases. In the case of the Pensky Martens flash point, the higher the catalyst / plastic residue ratio, the lower the flash point. It is concluded that the liquid product obtained does not meet the national specification of Diesel B5, but it resembles a Talara crude.
