Sustainable and efficient waste management requires involvement of symbiotic solutions to various types wastes, so achieve circular economy. Through this motivation, in study, combined thermochemical conversion (pyrolysis) plastics, biomass marble processing effluents physicochemical treatment sludge (K1) were studied. In combination, plastics petroleum-based synthetic aromatic (PET) aliphatic (PP) organics, while olive pomace-OP was natural agricultural residue. K1 mineral product, which first introduced the literature as pyrolysis catalyst by authors. co-pyrolysis polymers catalyzed containing CaCO3. The effect plastic type pyrolyzed material mixture ratio on fractions investigated. Moreover, recovery potential from discussed. catalytic co-pyrolysis, increasing mixture, pyrolytic liquid oligomer fraction increased solid (char) gas decreased. For 70%PP+15%OP+15%K1 product dominant, whereas with 60%PET+20%OP+20%K1 much more produced. thermal degradation char products did not exceed 2-3% up 600°C stability continues approximately 700°C reveals be used alternative areas a high resistance. contain alkanes, alkenes, acids, phenols, benzene, aldehydes, esters, alcohols, ketones. Benzene, acid alcohol groups dominant liquids, alkane, alkene alkyne gases.

Abstract The kinetics and thermodynamics of biomass pyrolysis are crucial for its design, optimization, industrial application. In this study, proximate analysis, together with higher heating value (HHV) kinetic thermodynamic studies water hyacinth (WH) wheat straw (WS) were performed. Nonisothermal thermogravimetric analysis (TGA) at rates 15, 20, 25 °C min −1 employed to investigate their experimentally. Detailed results from the HHV measurements both biomasses documented analyzed. Iso‐conversional revealed that effective activation energy varied significantly reacted fraction. For WS, average values 63.67 kJ mol 45.74 based on Flynn–Wall–Ozawa (FWO) Kissinger–Akahira–Sunose (KAS) methods, respectively. WH, corresponding 118.58 114.09 . Coats–Redfern model demonstrated TGA data obtained in an inert environment best described by a second‐order reaction mechanism ‘D3c’ three‐way diffusion model. Thermodynamic indicated WH WS is not spontaneous requires external input thermal decomposition. Both processes identified as endothermic, reactivity increasing advanced. comprehensive index (CPI) increased rates, suggesting elevated more favorable these biomasses. These findings contribute better understanding mechanisms highlight potential bioenergy production.

Thermogravimetric Assessment of Biomass: Unravelling Kinetic, Chemical Composition and Combustion Profiles

Fire, Год журнала: 2024, Номер 7(11), С. 396 - 396

Опубликована: Окт. 31, 2024

Thermogravimetric analysis (TGA) was performed on six samples of pine wood, poplar sawdust and olive residue, the kinetic parameters were evaluated by using isoconversional models. The hemicellulose, cellulose lignin contents also estimated Fraser–Suzuki deconvolution method. In addition, a range thermodynamic combustion indices calculated. Significant correlations found between kinetic, parameters. ignition index showed an inverse relationship with activation energy, whereas burnout correlated enthalpy values for most samples. Higher heating rates during TGA increased efficiencies but decreased stability. Differences in behaviour detected residues, which had much higher content (51.2–56.9%), woody biomass (24.2–29.2%). Moreover, sample highest ash exhibited some distinctive characteristics, including lowest high value index, coupled indicating less favourable than other particle size to be critical both efficiency safety.
