Abstract

Production of biodiesel has been increased globally during the last decade to overcome the problems of increasing prices of petro-diesel and depletion of fossil fuels. The present study aims to utilize agro-waste sugarcane bagasse (SCB) to synthesize heterogeneous acid catalyst for biodiesel production using waste cooking oil. Waste sugarcane bagasse was converted into biochar through partial carbonization and activated via sulfonation by using 1M, 3M, 5M and concentrated sulfuric acid at a sulfonation temperature of 180 ℃ for 5 h. The prepared catalysts were characterized by using Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), and CHNS analyzer. The prepared catalyst exhibited an excellent surface area of 20.78 m2/gm and a total acid density of 3.94 mmol/gm. The yield of biodiesel was optimized over the influence of four process parameters in the range of reaction temperature (40-70 ℃), methanol to oil molar ratio (5:1-20:1), catalyst loading (1-7 wt.%) for 5-25 min using microwave reactor. The maximum conversion of 95.45% and yield of 92.12% was obtained under optimum conditions; catalyst loading 5 wt.%, methanol to oil molar ratio (15:1), temperature (60 ℃) after 15 min. The results of experiments were validated by using response surface methodology which validated the predicted model. Kinetic study of experiments depicted that the use of sulfonated catalyst lowered the activation energy (10.5 kJ/mol) and reactants attained equilibrium point after a short interval of time under microwave heating. Moreover, reusability of catalyst up to seven cycles with 77.34% yield of biodiesel using low-grade feedstock showed that the catalyst is stable and can be used for sustainable biodiesel production. The utilization of wastes for catalyst synthesis as well as for biodiesel production can help us to minimize the overall production cost of biodiesel.
