Insight into the catalytic transformation of the waste products of some edible oils (corn oil and palm oil) into biodiesel using MgO/clinoptilolite green nanocomposite

Mohamed Gameel Basyouny et al.

Summary: The urgent demand for renewable, eco-friendly and safe energy resources instead of traditional fossil fuels is the most critical issue facing the contemporary world. This study synthesized Clinoptilolite decorated with nano MgO as a potential basic catalyst, which showed significant enhancement in surface area, ion exchange capacity, and total basicity, achieving high yields of biodiesel from corn oil and palm oil that meet international standards.

Process optimization of biodiesel production from waste cooking oil by esterification of free fatty acids using La3+/ZnO-TiO2 photocatalyst

Mengli Guo et al.

Summary: In this study, a highly active and reusable La3+/ZnO-TiO2 photocatalyst was prepared for the esterification of free fatty acids in waste cooking oil, leading to the production of biodiesel through a two-step method. The catalyst showed stable activity and the biodiesel produced met industry standards, validating the potential of La3+/ZnO-TiO2 as a new photocatalyst for biodiesel production.

Impact of diesel e Algae biodiesel- Anhydrous Ethanol blends on the performance of CI engines

Velmurugan Kulanthaivel et al.

Summary: Green biofuels like ethanol and biodiesel are being considered as potential solutions to reduce pollutant emissions and decrease society's reliance on fossil fuels. Experimental evaluations on ternary blends of diesel, biodiesel, and ethanol in a diesel engine show improvements in engine performance, optimization of fuel injection timing, and effects of ethanol on combustion delay. Specific conditions of rotation, torque, and fuel injection moments are considered to determine the effects of different ethanol proportions on efficiency in the engine supplied with blends.

Optimization of diesel engine performance and emission parameters of Karanja biodiesel-ethanol-diesel blends at optimized operating conditions

Krishna Shrivastava et al.

Summary: This study examines the use of Karanja biodiesel, ethanol, and diesel blends in the Indian subcontinent, focusing on the effects on engine performance, emissions, and combustion responses. Experimental results show that while using these biofuels can reduce emissions compared to using diesel, there are some negative impacts on engine performance.
