SUMMARY:

Plastics have a wide application in several sectors, due to their great versatility, lightness, cost and functionality. Therefore, there has been a rapid rise in its use, resulting in greater disposal, often in the environment, which can take hundreds of decades to decompose. Given this scenario, it is necessary to study new forms of treatment and disposal, less aggressive to the environment such as pyrolysis. Pyrolysis emerges as an alternative that presents a promising technology, capable of transforming plastic waste into condensable products such as oil, solid product and gases at moderate temperatures between 400 and 700ºC, in the absence of atmospheric oxygen. Therefore, this work brought the possibility of obtaining fuel oil from the mixture controlled by experimental planning associated with the response surface of packaging intended for the environment of polystyrene and high density polyethylene, aiming at the modeling and optimization of the pyrolysis process. through the Normal Boundary Intersection (NBI) algorithm. The raw material for the production of fuel oil in this work was polystyrene and high-density polyethylene recycled from post-consumer styrofoam packaging and transparent plastic bags, with Zeolite added as a catalyst and a temperature of 400ºC varying the waste masses and heating ramp as proposed in the experiments. The total time of each experiment was determined to be 90 min. It was possible to verify that smaller heating ramps, larger polystyrene masses and lower high-density polyethylene masses favored a greater generation of oil volume and lower specific mass of this oil.
