Exploring Onopordum acanthium L. as a sustainable feedstock for biodiesel production: process optimization and characterization

The growing demand for sustainable energy solutions has intensified interest in Biofuels.  Petroleum biofuel is non-toxic, eco-friendly, and biodegradable as compared to the diesel. Now a day’s biodiesel is produced by edible oil which comprises food verses oil problem, but it can be solved by using non-edible, using a...

Microwave-Assisted Transesterification of Waste Cooking Oil Using Modified CaO Catalyst for High-Purity Biodiesel Production

Biodiesel is a renewable alternative fuel capable of partially or fully replacing conventional diesel in compression ignition engines. Waste cooking oil (WCO) represents a sustainable feedstock for biodiesel production; however, its high free fatty acid (FFA) content must be reduced below 1% to prevent emulsion formati...

Assessing the Potential of Heterogeneous Basic Catalysts for the Production of Biodiesel from Vegetable Oil Extracts

This study investigates the production of biodiesel, specifically fatty acid methyl esters (FAME), derived from waste orange peel oil (OPO) via transesterification. A mixed metal oxide heterogeneous catalyst was synthesized using a coprecipitation method in the presence of soluble sodium carbonate and evaluated for the...

Transformation of Residual Fatty Biomass into Green Diesel: Optimization of the Reaction Parameters over a MoNi/SiO2 Catalyst

To advance the circular bioeconomy and mitigate fossil fuel dependency, this study evaluates the catalytic valorization of diverse residual fatty biomasses into high-quality renewable (green) diesel. A high-loading bimetallic MoNi/SiO2 catalyst (metal loading: 50 wt %, atomic ratio: Ni/(Ni + Mo) = 0.95) was developed...
