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.
在本工作中，我们使用锌掺杂氧化钙作为纳米催化剂，从蓖麻油中生产生物柴油。通过响应面法获得了最佳的生物柴油转化率和绿色化学平衡条件。优化了五个绿色化学参数，如碳效率、原子经济性、反应物质效率、计量因子和环境因子。在甲醇与油的摩尔比为 10.5:1、温度为 57°C、时间为 70min 和催化剂浓度为 2.15%的最佳条件下，可持续生物柴油产率为 84.9%，绿色化学平衡为 0.902。合成的生物柴油通过 GCMS 和 FTIR 进行了表征，并测定了其物理化学性质。基于实验研究，使用 SuperPro Designer 模拟了每年 2030 万公斤产能的工厂。考察了油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分析。优化和技术经济分析为商业生物柴油生产提供了可持续的平台。
