In this study, biodiesel production from yellow horn (Xanthoceras sorbifolia Bunge.) seed oil using ion exchange resin as heterogeneous catalyst was investigated. After illustration of the mechanisms of transesterification reactions catalyzed by typical ion exchange resins, the factors affecting microwave-assisted transesterification process were studied. A high conversion yield of about 96% was achieved under optimal conditions using high alkaline anion exchange resins as catalyst. Analyzing the FAMEs composition by GC-MS and main physical-chemical properties demonstrated that the biodiesel product prepared from yellow horn seed oil was of high quality. Compared with conventional alkali catalyst, the outstanding characteristics of reusability and operational stability made the resin catalyst more predominant for biodiesel production. In addition, a comprehensive kinetic model was established for analyzing the reaction. The results of present research showed that microwave-assisted transesterification process catalyzed by high alkaline anion exchange resin was a green, effective and economic technology for biodiesel industry.
本研究以离子交换树脂为非均相催化剂，从黄刺玫籽油中生产生物柴油。阐述了典型离子交换树脂催化酯交换反应的机理，研究了影响微波辅助酯交换过程的因素。在最佳条件下，使用高碱性阴离子交换树脂作为催化剂，可获得约 96%的高转化率。通过 GC-MS 分析脂肪酸甲酯 (FAMEs) 的组成和主要理化性质，表明用黄刺玫籽油制备的生物柴油质量较高。与传统的碱催化剂相比，树脂催化剂具有可重复使用和操作稳定性的突出特点，更适合生物柴油的生产。此外，还建立了用于分析反应的综合动力学模型。研究结果表明，高碱性阴离子交换树脂催化的微波辅助酯交换过程是一种绿色、有效、经济的生物柴油工业技术。
