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.

Catalytic Deoxygenation of Lipids for Bio-Jet Fuel: Advances in Catalyst Design and Reaction Pathways

Catalysts, Journal Year: 2025, Volume and Issue: 15(6), P. 518 - 518

Published: May 24, 2025

To address global climate change and the energy crisis, there is an urgent need to meet human demands through utilizing renewable sources. The deoxygenation of lipids produce liquid biofuels has emerged as a promising alternative, particularly for carbon emission reduction in aviation industry. This review critically examines recent progress catalyst development reaction control strategies lipid deoxygenation. Emphasis focused on design different kinds catalysts requirements, including noble metal catalysts, non-noble compound with such morphology control, utilization support interactions, constructing synergistic effects between acid centers oxygen vacancies. networks, mechanisms, selectivity deoxygenation, cracking, isomerization, aromatization are comprehensively discussed. Finally, we propose that it requires focusing precise regulation multiple active sites optimizing performance reusability. It essential integrate situ characterization deepen study structure–active relationships explore mechanisms within complex systems.

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).
