Cutting Cost Technology for the Preparation of Biodiesel Using Environmentally Benign and Cheaper Catalyst

摘要

Herein, a promising egg shell derived catalyst (ESDC) was prosperously developed by calcination of egg shell powder and exercised to the transesterification of Helianthus annuus L oil for the synthesis of biodiesel fuel. Synthesized egg shell derived catalyst affirmed remarkable catalytic activity for transesterification of Helianthus annuus L oil with 2.5 % catalyst dose (w/w). ESDC was duly characterized by FT-IR, XRD, BET, TPD-CO2, TGA and SEM analysis. While, Helianthus annuus L oil and biodiesel were duly characterized by FT-IR as well as H-1 and C-13 NMR spectroscopic techniques. From the obtained results, it can be concluded that 1:8 oil to methanol molar ratio revealed 99.2 % biodiesel yield in 2 h reaction time with 2.5 % catalyst dosage at 65 A degrees C reaction temperature.
