“…The main effect of the temperature increase is the increase in oxygen‐free aromatics and the decrease in oxygenated compounds. Izzatie et al co‐pyrolysis of rice straw and polyethylene terephthalate was carried out at different temperatures (450, 500, 550, 600°C) at ratio 1:1 by using fixed bed drop‐type pyrolysis in atmospheric conditions 42 . The temperature of 550°C is produced the highest amount of oil (36 wt%) 47 .…”

In this study, waste polyethylene terephthalate (wPET) was converted to liquid fuel by the pyrolysis method. It was also investigated both effects of microwave pre‐treatment and catalyst (sodium borohydride) on total conversion and oil + gas yield. The reaction temperature of 375–425°C and the reaction time of 30 min are sufficient for the pyrolysis of waste plastic samples in a batch reactor. In the pyrolysis of wPETs, the highest oil + gas yield of 45% was obtained under the conditions of reaction temperature of 425°C and reaction time of 30 min. The highest total conversion was 62% of microwave pre‐treated wPETs under catalytic conditions. It can be argued that microwave pre‐treatment and NaBH4 influence the oil + gas yield in pyrolysis experiments. According to the gas chromatography–mass spectrometry (GC–MS) analysis results of the oil products, they consist of aromatic, mono and multi‐ring aromatic compounds and polyaromatic compounds. Higher heating values of the solid products obtained in pyrolysis are approximately 4000–6000 cal/g. According to X‐ray diffraction analysis (XRD) of the solid products, they consist largely of crystalline terephthalic acid (C8H6O4).

“…Co-pyrolysis of polyethylene terephthalate (PET) and biomass can reduce the generation of aromatic polycyclic species, operating under moderate temperatures; however, under higher temperatures, such species formation tends to increase. Izzatie et al [167] carried out rice straw and PET co-pyrolysis at a 1-to-1 ratio in a fixed-bed reactor, under 723, 773, 823 and 873 K. They obtained 36% of bio-oil, 44.67% of gasses and 19.33% of solid residue. Çepeliogullar and Pütün, [168] co-pyrolyzed hazelnut shell and PET, at a 1-to-1 ratio, at 773 K. Compared to pyrolysis of biomass alone, the bio-oil and gas fractions presented higher yields (10.67% and 6.40%, respectively), while water and solid production decreased by 13.56% and 4.67%, respectively.…”

The pyrolysis of lignocellulosic biomass is a promising technology for obtaining renewable chemicals and fuels to replace fossil-based products. However, due to the complexity of the lignin, cellulose and hemicellulose molecules, a large variety of compounds are often formed, making commercial implementation difficult. The use of a catalyst during reactions has been recognized as one of the major improvements in pyrolysis, allowing the production of selected compounds. Moreover, the large number of available catalysts opens up a wide range of possibilities for controlling the reaction network. Zeolites, hierarchical zeolites, alkali and alkaline earth oxides, transition metals and carbonaceous materials, among others, have been investigated in the pyrolysis of a variety of biomasses. In addition, bifunctional catalysts play a role in pyrolysis, as well as the addition of plastics as hydrogen donors. This review aims to present and discuss in detail state-of-the-art catalytic pyrolysis, focusing on the relationships between the properties of the catalysts and the obtained products. A guideline for selecting catalysts for lignocellulosic biomass is also provided.
