Conversion of hazardous waste cooking oil into non-fuel value added products

International Journal of Ambient Energy, Journal Year: 2024, Volume and Issue: 45(1)

Published: May 6, 2024

Rise in population, urbanisation, and socioeconomic growth have led to amplified food consumption, globally. Increased consumption of vegetable oil for frying cooking various items households, restaurants, cafeterias instigates the generation millions tons waste (WCO) across jurisdictions. Inappropriate disposal hazardous WCO blocks drainages, contaminates waterbodies, exacerbates environmental degradation. Conversion into valuable products remains a realistic sustainable strategy management. This review delves recent advances deployment as low-cost feedstock non-fuel such biolubricant, bioplasticizer, bioasphalt, 3D printing resin. In this regard, work describes generation, collection, pretreatment, characterisation products. addition, major challenges future research directions conversion are highlighted before conclusion. The study recommends commissioning multidisciplinary unearthing robust collection systems, novel pretreatment methodologies, innovative technologies WCO.

Advanced computational modelling for biofuel catalyst optimization: enhancing beta zeolite acidity for oleic acid upgrading

Biofuel Research Journal, Journal Year: 2024, Volume and Issue: 11(03), P. 2194 - 2210

Published: Aug. 31, 2024

We explore here, through reactive force field (ReaxFF) molecular dynamics simulations, oleic acid upgrading on beta zeolite (BEA) regulated with nine silica-to-aluminium ratios (SARs) to investigate their acid-catalyzed deoxygenation and coking susceptibility. The selected computational descriptors involved conversion, hydrodeoxygenation, decarboxylation/decarbonylation selectivity, biofuels yield, coke deposition characteristics. Simulations were validated by 20.3 SAR available experimental data used for the systematic study. High selectivity was found be related structural sensitivity of BEA(100) mechanism. ReaxFF simulations revealed that altering Al-substitution could greatly promote biofuel formation. Specifically, SARs towards mid-region (SAR 47) favored gasoline production, while 31 exploited diesel-like hydrocarbons. An optimum ratio 37.4 achieved maximum conversion (69.8%), high yields diesel fuels (15.6 20.4 wt%, respectively) moderate (8.6 wt%). Density functional theory screening metallic dopants allowed investigating susceptibility, obtaining Cu-BEA structure optimal carbon O-moiety adsorption (-3.89 -1.8 eV, respectively). Furthermore, economic environmental analysis showed Cu-dopped BEA displayed lowest market price global warming potential (71 USD/kg 2.8 kg CO2-eq/kg).

Published: Jan. 15, 2024

Abstract Catalytic pyrolysis of biomass is a promising process for the conversion agricultural residues into renewable bio-oils, wherein zeolites play key role in their upgrading. In this work, peanut shell was catalysed by micro/mesoporous ZSM-11 modified incorporation zirconium. Mesopores were generated microporous zeolitic structure post synthesis alkaline treatment using potassium hydroxide as basic medium. The effect and its parameters studied detail. obtained materials extensively characterized. Results showed that maintained crystalline after desilication presented excellent textural properties, such high BET surface. Zirconium increased amount Lewis Brønsted acid sites. Pyrolysis tests presence material remarkably selectivity to 2,5-dimethylfuran (DMF), potential biofuel with energy density, among other value products chemical industry. Therefore, zeolite Zr an catalyst wastes.
