“…These results were in line with those found by other authors, who reported obtaining about 80 wt% of liquid fraction, which is the main product from PS pyrolysis [42]. Product yields are remarkably influenced by reactor type and operational conditions, but there is a general consensus that temperatures between 500 ºC to 600 °C and reaction times ranging from 15 to 45 min are the optimal conditions to ensure the highest liquid yields during PS devolatization [23].…”

“…Indeed, the main components in the liquid were styrene, its dimer and trimer, toluene and ethyl-benzene. As several researchers have reported, these components are the principal ones remaining after PS pyrolysis [20,24,42,47], with styrene being the major compound. Styrene monomers are usually produced through β-scission of C-C bonds of PS in the main chain [22].…”

Co-pyrolysis of grape seeds and polystyrene was conducted in a fixed-bed reactor, followed by an analysis of the organic phase for possible further application as a drop-in fuel. Significant positive synergistic effects were found with the addition of polystyrene (5-40 wt%) to the conventional pyrolysis of grape seeds. There was a considerable improvement in the organic phase yield, in particular, reaching values over 80 wt%, markedly higher than those obtained from conventional pyrolysis (61 wt%). Fuel properties of the bio-oil were also upgraded, with a decrease in oxygen content and an increase in the heating value. An organic bio-oil fraction with pH values ranging from 5.4 to 6.2 was obtained, reducing the issues associated with handling bio-oils obtained from common pyrolysis of lignocellulosic biomass, usually ranging between 2 and 3. Finally, an increment in the desired compounds, mainly aromatics, was also attained, while at the same time achieving a low content of undesired compounds, such as phenols. It was demonstrated that polystyrene can act as a H 2-donor, favoring oligomerization, cyclation and hydrodeoxygenation reactions into aromatic compounds.

“…In the Figure. 1 and 2 it can be seen that the increase in temperature is proportional to the increase in oil produced, the test is not passed to a higher temperature, because according to [11] the temperature of 500 o C, the percentage of oil will decrease, while the percentage of gas will increase.…”

Plastic distillation with pyrolysis method is one of the ways that can be used to convert plastic waste into useful chemicals and fuel oil. The purpose of this research is to design a simple plastic waste distillation design model, knowing the oil yield that can be obtained and the calorific value of oil from plastic distillation. The distillation device consists of a 12-liter volume reactor and a condenser with 0.5-inch copper pipe formed spiral with a total length of 1.5 meters and liquid cooled. The test was carried out with 2 kg Polyethylene Terephthalate type plastic material per process with 3 variations of temperature of 300 ° C, 350 ° C, 400 ° C and using LPG as fuel. The test results, the highest amount of oil produced is 49 gr at a pyrolysis temperature of 400 ° C with the heating value obtained from the distillation oil is 1537 J / gr.

“…A obtenção desse material pode ser feita, entre outras maneiras, pela pirólise de resíduos plásticos (Miandad et al 2016). Porém, a cera obtida por pirólise necessita ser purificada, afim de reduzir o teor de inorgânicos aderidos a sua estrutura.…”

RESUMO -A filtração da cera tem como objetivo reduzir o teor de inorgânicos, com o propósito de se ter um produto que atenda as exigências do mercado, isto é, uma cera com alto grau de pureza. Para isso, procedeu-se a filtração na qual variou-se a temperatura e pressão em faixas pré-determinadas estatisticamente para se obter uma maior quantidade de massa de cera filtrada. Diante disso, variou-se a temperatura de 140-170ºC e a pressão de 1-4 bar. Os resultados mostraram que a faixa de temperatura e pressão que se obteve maior massa de cera filtrada foi 170ºC e 2,5 bar, respectivamente. O percentual médio da remoção de impurezas da cera foi de 99,6%, garantindo a ótima qualidade do produto obtido.
