Abstract

Due to the shortage of energy resources and environmental issues, the study presents a sustainable approach for biodiesel production from waste cooking oil (WCO) catalyzed using magnetic catalyst-based biochar derived spent coffee ground (SCG). The added properties of magnetic and basic towards this catalyst was prepared by facile carbonization of one-pot SCG with Fe(III) and potassium hydroxide as activation agent at 700 °C for 2 h The characteristics of the catalyst was analyzed through Fourier transform spectroscopy (FTIR), scanning electron microscope coupled with energy dispersive X-ray (SEM-EDX), x-ray diffraction and Brunauer–Emmett–Teller (BET) surface area analysis. The performance of the catalyst was explored by the parametric effect on biodiesel yield from WCO. The parameters included are methanol to oil molar ratio, dosage of the catalyst and reaction time. The results showed that the catalyst exhibited excellent catalytic activity, with a biodiesel yield of 92.31% under 6:1 methanol to oil molar ratio, 1 wt% of catalyst dosage and 2 h of reaction time and the magnetism observation shows the catalyst own a magnetic property. In addition, the findings suggest that this approach offers a promising contribution for the development of a circular economy in the biofuel industry based on the utilization of waste to wealth.
利用废食用油制备生物柴油用废咖啡渣可持续磁催化生物炭的初步研究
由于能源资源短缺和环境问题,本研究提出了一种基于磁性催化剂的废咖啡渣生物炭催化废食用油(WCO)生产生物柴油的可持续方法。以Fe(III)和氢氧化钾为活化剂,在700℃条件下对一锅SCG进行了2 h的快速碳化,制备了该催化剂的磁性和碱性附加性能,并通过傅里叶变换光谱(FTIR)、扫描电子显微镜(SEM-EDX)、x射线衍射和Brunauer-Emmett-Teller (BET)表面积分析对催化剂进行了表征。通过参数对WCO生物柴油产率的影响,探讨了催化剂的性能。参数包括甲醇与油的摩尔比、催化剂的用量和反应时间。结果表明,在甲醇油摩尔比为6:1、催化剂用量为1 wt%、反应时间为2 h的条件下,该催化剂具有良好的催化活性,生物柴油收率为92.31%。此外,研究结果表明,这种方法为基于废物转化为财富的生物燃料行业循环经济的发展提供了有希望的贡献。
