废物利用是可持续发展的一个重要组成部分，废贝壳很少用于生产实用产品和工艺。大多数废弃贝壳富含CaCO3，一旦煅烧就转化为CaO，并且可以用作合成生物柴油的廉价和绿色催化剂。本文以龙虾壳和鸡蛋壳为绿色催化剂，以亚麻荠籽油为原料进行酯交换反应制备生物柴油。亚麻荠油作为生物柴油生产的原料是一种有吸引力的作物选择，因为它对寒冷天气，干旱和低质量土壤具有很高的耐受性，并且含有约40%的油含量。利用X射线粉末衍射、傅里叶变换红外光谱、扫描电镜等对废贝壳制得的催化剂进行了表征。用1H NMR和FTIR对产物生物柴油进行了表征。考察了醇油比、反应时间、反应温度、催化剂浓度等因素对反应的影响。当醇油摩尔比为12：1时，生物柴油的产率最高非均相催化剂在65°C下反应3小时。实验结果表明，酯交换反应符合一级动力学，并计算了不同温度下的反应速率常数和活化能。采用美国材料试验协会（ASTM）标准，对亚麻荠油和废贝壳制备的生物柴油与石油基柴油的燃料性能进行了比较。
Waste utilization is an essential component of sustainable development and waste shells are rarely used to generate practical products and processes. Most waste shells are CaCO3 rich, which are converted to CaO once calcined and can be employed as inexpensive and green catalysts for the synthesis of biodiesel. Herein, we utilized lobster and eggshells as green catalysts for the transesterification of Camelina sativa oil as feedstock into biodiesel. Camelina sativa oil is an appealing crop option as feedstock for biodiesel production because it has high tolerance of cold weather, drought, and low-quality soils and contains approximately 40% oil content. The catalysts from waste shells were characterized by X-ray powder diffraction, Fourier Transform Infrared Spectroscopy, and Scanning Electron Microscope. The product, biodiesel, was studied by 1H NMR and FTIR spectroscopy. The effects of methanol to oil ratio, reaction time, reaction temperature, and catalyst concentration were investigated. Optimum biodiesel yields were attained at a 12 : 1 (alcohol : oil) molar ratio with 1 wt.% heterogeneous catalysts in 3 hours at 65°C. The experimental results exhibited a first-order kinetics and rate constants and activation energy were calculated for the transesterification reaction at different temperatures. The fuel properties of the biodiesel produced from Camelina sativa oil and waste shells were compared with those of the petroleum-based diesel by using American Society for Testing and Materials (ASTM) standards.
