“…The molar weight has a proportional relationship with the density; hence, an increase was noted with the increase in the pyrolysis temperature, indicating a higher mixture of heavy hydrocarbons (raw data are also presented in Table S7 of the Supporting Information, along with typical densities of hydrocarbon mixtures). A higher density in the pyrolysis oil can be attributed to more absorbance of oil on catalysts used in the pyrolysis process, which also influences (decreases) the production of oils as the operating temperature increases. , Aromatic are within the density range of 0.88–0.95 g mL –1 associated with a high aromatic content increasing with respect to the pyrolysis temperature (Table S7 of the Supporting Information) . The carbon residue (potential coke) was lower with samples extracted at 600 °C (Table and Figure S8 of the Supporting Information), which was expected because lower operating temperatures are associated with a longer residence time that provides higher cracking of products .…”

“…It is an upgrading process of oils to the hydrocarbon (HC) fuel level for demonstration use. 9 There are two types of hydrotreatment: One is conducted at mild temperatures, where molecules can be saturated without significantly affecting the boiling temperature of the components in the oil, because there is no cracking involved. The other type is known as destructive hydrotreatment or hydrocracking, which combines cracking and saturation in a single step.…”

Upgrading fuels is an essential requirement to reach environmental specifications, namely, in removing sour components deemed hazardous nowadays and that cause fouling and disturb operations in downstream industry too. A lack of studies that report fundamental data also exist in the literature, as to the impact of hydrotreatment on thermochemical conversion products of plastics. We hereby report for the first time in this communication the effect of hydrotreatment on the products of plastic pyrolysis. Two types of pyrolysis products, oils and wax, were extracted from fluidized bed reactor pilot-plant operations at two operating temperatures (600 and 700 °C). These were subjected to hydrotreatment in a batch reactor over a Pt/Al2O3 catalyst for 6–8 h. Dependent upon the sample type, the hydrotreatment temperature reached 350 °C and was initialized at 140 °C. The hydrotreatment reactor handles a 180 barg pressure, and the operating pressure was kept steady in operation during measurements. The pressure rates (0.29–0.62 bar h–1), which decreased with the temperature (140–200 °C), were also recorded. The olefinic compounds were saturated from wax post-hydrotreatment and detected by alteration of carbon singular and double bond existence. Naphthalene and paraffins were also eliminated from oils treated, as confirmed by infrared spectroscopy and chromatography. The conversion during the hydrotreatment reduced the reactivity of the pyrolysis oil and promoted the production of diesel and kerosene production. It is therefore recommended to extend these types of studies using different catalysts that can provide environmental specifications to fuels with minimal costs in the near future as an essential route for integrated operations in industry.

The co-hydrotreatment of pyrolysis bio-oils and vegetable oils could facilitate the integration of bioderived fuels into existing fuel infrastructures without significant modifications. Co-hydrotreatment studies with different PL/WCO blend ratios (0, 10, 20, 30, and 40 wt %) were conducted over the NiMo/γ-Al 2 O 3 catalyst. The coke formation value for WCO was 0.7 wt % and ranged between 1.5 and 2.5 wt % with the increase of pyrolytic lignin in the blend. The data suggest that coke is formed from both the sugar-and lignin-derived oligomers since the coke yield reported in this study is comparable with the coke yield obtained by coprocessing the bio-oil fraction without light oxygenate compounds, based on previous studies. All blends are recommended for co-hydrotreatment based on coke yield. The resulting organic phase was distilled into hydrocarbons at <150 °C, 150 to 250 °C, and 250 to 350 °C. The organic product's overall hydrocarbon distribution was strongly dependent on the pyrolytic lignin concentration. The yield of the distillation cut with a boiling point range between 250 and 350 °C was higher in the hydrotreated samples, with more than 20% during distillation. Twodimensional GC×GC was used to determine carbon distribution on the combustibles. FTIR and UV fluorescence spectra showed that most feedstocks were converted to potential combustibles for transportation applications after hydrotreatment. The distillation cuts properties, such as density, viscosity, and surface tension, were reported and compared to transportation fuel properties. Hydrocarbon yields reveal the potential of cohydrotreatment to upgrade pyrolytic lignin into valuable products. These findings provide useful insights into utilizing pyrolytic lignin to produce promising combustibles suitable for transportation applications.
