Plastics represent an important share in the solid waste generated by cities, and as consequence, it is important to evaluate methods that allow their disposal and/or valorization. This work studies the production of liquid fuels from high density polyethylene recover from post-consumer plastics, through the use of thermal and catalytic pyrolysis. For the experimental work, post-urban high density polyethylene washed was used, cut and sieved in sizes 2-4 mm, 4-6 mm and 6-8 mm. The tests were carried out in a tubular vertical reactor operated in vacuum and with a condensation system for the products. Three reactor temperatures were used (530, 560 and 590ºC), varying the size of particle between those indicated. From all tests, the conditions that produced the highest yield were replicated to include the effect of adding a catalyst. 5 grams of FCC equilibrium catalyst from a local refinery was used. The operating conditions that provided the maximum yield among those studied were a pressure of 34.7 kPa abs, 20ºC/min heating rate, particle size of 4-6 mm, furnace temperature of 1000ºC and reactor temperature of 560ºC. The yields were 89% liquid, 7% gases and 3% solids. The use of catalyst reduced the yield of liquid product but it improved the transport properties such as viscosity and pour point. In conclusion, the conditions that allow the production of a liquid fuel similar to diesel were found. The use of catalyst provided a product with higher yield of gasoline instead of diesel, but in both cases, it cannot be directly used as a motor fuel in replacement of refinery fuel.
