The use of tomato plant residues (i.e., stems, leaves, etc.) as a substrate for catalytic pyrolysis biomass was investigated. A comprehensive study conducted to investigate the impact catalysts on performance different fractions gas, biosolid, waxes, and bioliquid) well distribution products within bioliquid. employed in this were derived from two distinct types zirconia. first type synthesized by conventional sol-gel method, while second prepared with modified method aimed at improving presence mesopores. This modification involved incorporation Pluronic 123. These materials designated ZrO2 ZrO2P25, respectively. Both zirconia used supports tungstophosphoric acid (H3PW12O40, TPA), heteropolyacid Keggin structure, preparation strong sites. results demonstrated that bioliquid yield non-catalytic fast waste approximately 23% obtained contained wide variety molecules, which detected quantified GC-MS. In catalysts, both substantially modified. Furthermore, possible sugar degradation pathways leading formation molecules present pyrolytic bioliquids thoroughly examined. indicate physicochemical characteristics specifically their pore size acidity, have significant selectivity processes towards valuable including anhydro-sugars furanic derivatives such furfural furfuryl alcohol.

Biochar in the Remediation of Organic Pollutants in Water: A Review of Polycyclic Aromatic Hydrocarbon and Pesticide Removal

Nanomaterials, Год журнала: 2024, Номер 15(1), С. 26 - 26

Опубликована: Дек. 27, 2024

This review explores biochar’s potential as a sustainable and cost-effective solution for remediating organic pollutants, particularly polycyclic aromatic hydrocarbons (PAHs) pesticides, in water. Biochar, carbon-rich material produced from biomass pyrolysis, has demonstrated adsorption efficiencies exceeding 90% under optimal conditions, depending on the feedstock type, pyrolysis temperature, functionalization. High surface area (up to 1500 m2/g), porosity, modifiable functional groups make biochar effective adsorbing wide range of contaminants, including toxic metals, nutrients. Recent advancements production, such chemical activation post-treatment modifications, have enhanced capacities, with engineered achieving superior performance treating industrial, municipal, agricultural effluents. However, scaling up applications laboratory research field-scale wastewater treatment poses significant challenges. These include inconsistencies variable environmental high cost large-scale logistical challenges handling deploying at scale, need integration existing systems. Such impact practical implementation biochar-based remediation technologies, requiring further investigation into production methods, long-term assessments, field-level optimization strategies. underscores importance addressing these barriers highlights offer sustainable, environmentally friendly, economically viable treatment.
