“…The pyrolysis of polyolefins, which account for two-thirds of the generated waste plastics, is commonly aimed at producing oil , and at fast pyrolysis conditions, i.e., low temperature, high heating rate, and short residence time of volatiles, waxes (mainly C 21+ ). , Polyolefin pyrolysis oil has attracted significant attention for its direct use in internal combustion engines due to its high calorific power (35–45 MJ kg –1 ), high cetane index (46–63), which strongly depends on the pyrolysis temperature; and water-free chemical composition (mainly aliphatics and olefins). − However, the composition of the oil must be upgraded to comply with the strict norms of automotive fuels.…”

The catalytic cracking of high-density polyethylene pyrolysis waxes has been investigated with the aim of promoting the production of fuels. The runs have been conducted in a CREC riser simulator reactor under industrial fluid catalytic cracking conditions: 500−560 °C; catalyst/oil ratio, 5 g cat g wax −1 ; and contact time, 6 s. Three commercial equilibrium catalysts with different compositions have been used, with the aim of determining the effect of the properties of the catalysts on the conversion, yield, and composition of the following fractions of products: dry gas (C 1 −C 2 ), liquefied petroleum gases (LPG, C 3 −C 4 ), and naphtha (C 5 −C 12 ). The acidity and acid strength of the catalyst boost the production of not only naphtha (showing values of RON of up to 104.8) but also dry gas, LPG, and coke fractions. Obtained yields of naphtha and LPG fractions are in the ranges of 23.8−31.1 and 13.7−18.1 wt %, respectively, which means that reached conversion has been of 41.4−62.9 wt %. Furthermore, the concentrations of olefins and aromatics in the naphtha fraction are in the ranges of 35.8−48.1 and 26.0−37.9 wt %, respectively.

Through an experimental study, this work focused on finding the influence of exhaust gas recirculation (EGR) on waste plastic pyrolysis oils (WPPOs) with diesel as a base comparison fuel. The results show the amount of carbon monoxide emissions seemed to decrease at low engine loads up to intermediate loads of (50%), thereafter continued to increase significantly but marginally. Among fuels tested, blend WPPOB100 reported the highest BSFC, at 0% EGR flow rate. The value was 0.4751g/kW.hr. compared with 0.7235 g/kW.hr. at 30% EGR flow rate. Increased blend ratio had a direct decrease in brake power linearly. At 30% engine load, CD, WPPOB10, WPPOB20, WPPOB30 and WPPOB40 recorded values of 2.125 kW, 2.15 kW, 2.05 kW, 1.98 kW, 1.86 kW and 1.75 kW, respectively. Exhaust gas temperature (EGT) at 30% EGR flow rate, blend WPPOB10 had the highest reduction in temperature compared with the any other WPPO blends at 320°C. Increased blend ratio and EGR percentage flow rate increased smoke emissions within the test fuels blends. At 15% EGR flow rate, the following data were recorded: 7.53%, 7.1%, 6.72%, 6.25%, 6.0% and 5.4% for CD, WWPO10, WPPO20, WPPO30, WPPO40 and WPPO100, respectively.

“…The pyrolysis oils that were tested via GC-MS were usually obtained from specific kinds of plastics [11][12][13][14] or their partial mixture [15], and a meticulous molecular description of the samples was usually omitted. In this respect, common model plastics were PS [16][17][18]; PET, HDPE, LDPE, PP, PS, and PVC [11]; HDPE, LDPE, PP, and PS [19]; PE [20,21]; LDPE and HDPE [22]; LDPE, the mixture of HDPE and LDPE, PP, and HDPE [23]; PP [24]; and PP and LDPE [25]. The complete chemical fingerprint of the pyrolysis oil from mixed plastic waste was rarely studied, and only a few compounds were usually identified in their pyrolysis oils, while analytes were usually not detailed since they were grouped according to specific criteria, such as the carbon number or chemical class [26].…”

A detailed molecular fingerprint of raw pyrolysis oil from plastic wastes is a new research area. The present study focuses for the first time on the chemical recycling of plastic marine litter; we aim to chemically characterize the obtained raw pyrolysis oil and its distillates (virgin naphtha and marine gasoil) via GC-MS and FT-IR. For all samples, more than 30% of the detected compounds were identified. 2,4-dimethyl-1-heptene, a marker of PP pyrolysis, is the most represented peak in the chemical signature of all the marine litter pyrolysis samples, and it differentiates commercial and pyrolysis marine gasoil. The presence of naphthalenes is stronger in commercial gasoil, compared to its pyrolysis analog, while the opposite holds for olefins. The overlap between the two molecular fingerprints is impressive, even if saturated hydrocarbons are more common in commercial gasoil, and unsaturated compounds are more common in the gasoil derived from pyrolysis. A technical comparison between the commercial marine gasoil and the one obtained from the marine litter pyrolysis is also attempted. Gasoil derived from marine litter fully complies with the ISO8217 standards for distillate marine fuel. On the other hand, the virgin naphtha is particularly rich in BTX, ethylbenzene, styrene, and alpha olefins, which are all important recoverable platform chemicals for industrial upcycling.
