Abstract

Energy demand and need for sustainable sources for fuel production have resulted in the development of alternative fuel technologies. Waste cooking oil (WCO) and algal oil (AO) extracted from Chlorella variabilis have been transesterified to yield WCO biodiesel (WCOBD) and AO biodiesel (AOBD). The present study aims to produce biodiesel by blending optimised proportion (1.25%) of AO with WCO to get 1.25AO-WCO for making biodiesel with improved properties. The reaction conditions for transesterification of 1.25AO-WCO were augmented by response surface methodology tool to attain supreme fatty acid methyl ester (FAME) yield of 98%. Fourier transform infrared spectroscopy (FTIR) of 1.25AO-WCO BD were performed to prove the production of biodiesel and their FAME profile is determined using gas chromatography with flame ionisation detector (GC-FID). Properties of 1.25AO-WCO BD were determined for 1.25AO-WCO BD and observed to meet ASTM standards apart from exhibiting better properties than biodiesel made from 100% WCO.

利用FTIR和GC-FID对废食用油藻油生物柴油进行结构和成分评价，以改善燃料性能

能源需求和对燃料生产的可持续来源的需求导致了替代燃料技术的发展。研究了从小球藻中提取的废食用油(WCO)和藻油(AO)的酯交换反应，制备了WCO生物柴油(WCOBD)和AO生物柴油(AOBD)。本研究的目的是将优化比例(1.25%)的AO与WCO混合制备生物柴油，得到1.25AO-WCO，以制备性能更好的生物柴油。利用响应面法对1.25AO-WCO的酯交换反应条件进行了优化，得到最高脂肪酸甲酯(FAME)的收率为98%。用傅里叶变换红外光谱(FTIR)对1.25AO-WCO BD进行了验证，并使用气相色谱火焰离子化检测器(GC-FID)测定了其FAME谱。1.25AO-WCO BD的性能被确定为1.25AO-WCO BD，并且观察到除了表现出比100% WCO制成的生物柴油更好的性能外，还符合ASTM标准。

期刊介绍： WRSTSD is a multidisciplinary refereed review on issues that will be central to world sustainable development through efficient and effective technology transfer, the challenges these pose for developing countries, and the global framework for dealing with science and technology. The general theme of WRSTSD is to discuss integrated approaches to the problems of technology transfer within an urban and rural development context. The theme has been very carefully chosen to include science and technology and the challenges these represent in terms of sustainable development.
