在本工作中，锌掺杂的氧化钙被用作纳米催化剂用于从蓖麻油制备生物柴油。采用响应面法优化了生物柴油转化率和绿色化学平衡的最佳条件。优化了碳效率、原子经济性、反应质量效率、化学计量因子和环境因子等5个绿色化学参数。当醇油摩尔比为10.5：1，反应温度为57 °C，反应时间为70 min，催化剂浓度为2.15%时，生物柴油的可持续产率为84.9%，绿色化学平衡为0.902。采用GCMS和FTIR对合成的生物柴油进行了表征，并测定了其理化性质。在实验研究的基础上，利用SuperPro设计器对年产2030万kg的装置进行了模拟。分析了油品采购成本和生物柴油销售价格对投资回报率、投资回收期、内部收益率和净现值的敏感性。优化和技术经济分析为生物柴油的商业化生产提供了一个可持续的平台。
In the present work, zinc doped calcium oxide was used as a nanocatalyst for biodiesel production from castor oil. The optimal conditions of biodiesel conversion and green chemistry balance were obtained with response surface methodology. Five green chemistry parameters like carbon efficiency, atom economy, reaction mass efficiency, stoichiometric factor and environmental factor were optimized. The sustainable biodiesel yield 84.9% and green chemistry balance 0.902 was achieved at methanol to oil molar ratio 10.5:1, temperature 57 °C, time 70 min, and catalyst concentration 2.15%. The synthesized biodiesel was characterized by GCMS and FTIR, and physic-chemical properties were determined. Based on experimental study annually 20.3 million kg capacity plant was simulated using SuperPro designer. The sensitivity analysis of oil purchase cost and biodiesel selling price on ROI, payback period, IRR and NPV were investigated. The optimization and technoeconomic analysis provided a sustainable platform for commercial based biodiesel production.
