The study contains three experimental sets: 1) batch pyrolysis of POs; 2) continuous pyrolysis of WWTB; 3) continuous feeding of WWTB into a molten PO medium, which was previously fed to the round bottom tank reactor batch-wise. Individual WWTB pyrolysis yields a modest 18.7 wt% of liquid, predominantly influenced by elevated ash and fixed carbon content. Conversely, co-pyrolysis demonstrates positive synergies, with escalating polyolefin content boosting liquid yields, reaching a peak at 61.5 wt% with a WWTB:POs mixture (25:75, wt%), while concurrently suppressing gas production to 21.6 wt%. The primary chemical groups found in the liquid obtained from WWTB are phenol and phenolic compounds, with their abundance diminishing as the POs ratio in feedstocks increases. Analysis of non-condensable gases from WWTB reveals that approximately 57.7 wt% are oxygen-containing, predominantly CO and CO₂. Co-pyrolysis with POs at a 25:75 (wt%) ratio yields 47.1 wt% C₃H₆, resembling POs pyrolysis. The resulting solid products are rich in carbon and contains high ash. This research not only offers a detailed product analysis of WWTB but also sheds light on the dynamics of its co-pyrolysis with POs.

Reactive force field molecular dynamics (ReaxFF-MD) simulations were employed to explore its chemical degradation mechanisms. TGA revealed that the initial degradation of PEEK occurred above 540 °C, highlighting its exceptional thermal stability. Oxygen lowered the degradation temperature by approximately 20 °C, leading to a distinct two-stage process.

Py-GC/MS analysis showed that PEEK pyrolysis generated valuable phenolic compounds, primarily phenol and <em>p</em>-phenoxyphenol. Dibenzofuran, along with significant production of CO₂/CO and H₂O were the predominant oxidation products. Py-GC/MS and ReaxFF-MD combined demonstrated that ether and ketone groups cleaved initially, with terminal phenylene-carbonyl radicals breaking more readily than phenoxy radicals, resulting in early CO release. Aryloxy radicals underwent chain cleavage, hydrogen abstraction, and hydrogen transfer reactions to form various phenolics. Oxygen attacked the main chains to form •HO₂ and •OH radicals, which subsequently reacted with terminal rings through hydrogenation and hydrodeoxygenation.

The strategy of fuel/oxidizer interfacial control has been proved to effectively enhance the reaction efficiency of Al-based composites and thus improving the combustion properties of solid propellants. Ammonium perchlorate (AP) is commonly used as a high-energy oxidizer in solid propellant, and its thermal decomposition behavior directly affects the combustion characteristics of propellants. The addition of combustion catalysts can decrease thermal decomposition temperature and increase thermal reactivity of AP. As an emerging catalytic material, MoO_3-x quantum dots (QDs) with oxygen vacancies possess a high specific surface and strong charge adsorption capacity, which renders it a great potential for catalyzing AP.

The particle morphology, thermal decomposition kinetics and ignition properties of Al@AP/M_xO_y were investigated. The phase composition, morphology and particle size distribution for the condensed combustion products of composites were further analyzed. The decreased particle size and less unreacted Al content in CCPs indicated the increase of combustion efficiency between Al and AP.

The atomic inhibition mechanism of organic Na on tar formation was revealed, through inhibiting the formation path of tar, promoting tar condensation to coke, and enhancing the release of H₂O and other volatiles in tar. Additionally, through statistical analysis of Na-containing products and tracking real-time reaction trajectories, three primary pathways for the migration and transformation of organic Na were identified. First, organic Na breaks at the O-Na bond to form atomic Na, which then reacts with inorganic components like H₂O and -OH, a process that occurs frequently. The resulting atomic Na combines with gaseous hydrocarbons to form gaseous Na, which is subsequently released. Tar-Na is formed when atomic Na interacts with tar molecules.

Nevertheless, the mechanism of BDE-209 initiated by reactive radicals in the thermochemical decomposition process remains unknown. The density functional theory method is used to study the thermochemical decomposition behavior of BDE-209, with reactive radical reactions, and the formation mechanism of polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs). The results show that BDE-209 is not prone to self-decomposition due to its high bond dissociation energy (249.6 ∼ 281.4 kJ/mol) and HOMO-LUMO energy gap (7.10 eV). The reaction of BDE-209 with three active free radicals, including •H, Br•, and •OH, usually results in a variety of hypobromated products or important intermediates at low reaction energy barriers (52.9, 54.3, 50.4 kJ/mol). At 600 K, the branching ratio of H-abstraction reaction in the reaction system of •H and BDE-209 is 67.5 %.

The most favorable reaction pathway for the subsequent degradation of <em>ortho</em>-phenyl-type radical is IM10 → <strong>TS38</strong> → IM13. The participation of polymer materials increases the production of toxic PBDD/Fs. This is because the free radicals formed by the chain scission of the polymer can easily extract the <em>ortho</em>-Br atom of BDE-209, thereby promoting the formation of the precursor (<em>ortho</em>-phenyl radical) of PBDD/Fs.

The results indicated that low-molecular-weight (&lt;C₂₀) normal alkanes and pristane (Pr) are preferentially expelled from the shale before oil-cracking stages. In contrast, high-molecular-weight normal alkanes and phytane (Ph) are retained within the shale due to the relatively more robust interactions with kerogen, and polarity dominantly affects the composition fractionation during the expulsion of aromatic compounds. This led to significant discrepancies in ratios of saturated and aromatic hydrocarbon compounds between the collected oil and rock extracts, such as (<em>n</em>C₂₁+<em>n</em>C₂₂)/(<em>n</em>C₂₈+<em>n</em>C₂₉), Pr/Ph, and indicators related to methylnaphthalene, methylphenanthrene, methyldibenzothiophene, and trifluorene series. Trends of those molecular ratios reverse due to intensive thermal cracking at higher maturities. The fractionation heavily affects the accuracy of maturity comparison of aromatic hydrocarbon ratios in shale source rocks and related hydrocarbon accumulations, ultimately casting doubts on oil-source correlations. Moreover, the fractionation can misguide inferences regarding paleoenvironmental conditions based on the trifluorene series and the ternary diagram of the Ph/<em>n</em>C₁₈, Pr/Ph, and Pr/<em>n</em>C₁₇.

Digestate, originated from crop waste, was first utilized in slow, fast and microwave pyrolysis as an additional treatment post-AD for more green product generation. An alternative scenario was assessed whereby the original crop waste (the pre-AD crop) was pyrolyzed directly, without being first fed into an AD system, to evaluate and differentiate the pyrolytic products between this crop waste and the digestate. Around 95 wt% of pre-AD consists of mainly biopolymers: 16 wt% cellulose, 36 wt% hemicellulose, 15 wt% lignin, 29 wt% starch, and only 4 wt% of ash. Crop digestate, collected from the same crop waste AD system, was also analyzed more thoroughly. This analysis revealed that pre-AD changes primarily in the composition of starch and some hemicellulose, as well as an increase in ash content by almost double the amount. The pre-AD crop treated with slow pyrolysis at 355–530 °C yielded 50 wt% of bio-oil with a large amount of primary holocellulose derivatives. In contrast, the same pre-AD crop subjected to microwave pyrolysis for 5 min at a power input of 500 and 700 W generated between 17 wt% and around 26 wt% of bio-oil, characterized by a high acetic acid concentration and a small amount of sugars. Furthermore, biochars derived from the pyrolysis of pre-AD and digestate were evaluated for their capacity as sustainable agents for CO₂ adsorption for potential applications in reducing CO₂ emissions. The surface area of biochars derived from the pre-AD crop subjected to microwave and slow pyrolysis showed values ranging from 170 to 227 m²/g. Although the digestate is from the same pre-AD crop, the biochars derived using slow pyrolysis had less surface area, with values between 80 and 130 m²/g at around 400 °C, and an average of 175 m²/g at 500 °C; with fast pyrolysis 145–185 m²/g, and a range of 71–115 m²/g with microwave pyrolysis.

In this study, two solid wastes are used as raw materials to synthesize hierarchically porous ZSM-5 catalyst based on solvent-free method, aligning with the target of “green chemistry”.
