摘要

以天然衍生的氧化钙(CaO)和磺化碳催化剂为催化剂,在适度的操作条件下实现了生物柴油高产率。然而,很少有研究对绿色催化剂氧化钙和磺化碳催化剂同时催化工业规模生产生物柴油的经济可行性进行评估。目前的研究旨在评估两种工艺催化的生物柴油工业规模生产的技术能力和经济可行性。CaO催化剂和2)磺化碳催化剂。通过Aspen Hysys进行工艺模拟,对先前设计的碱催化剂(CaO)和酸催化剂(磺化碳)的两种工艺配置进行材料和能量平衡。在进行设备选型和成本计算后,开始进行经济分析。计算了各工序的总资本投入、总制造成本、收益率、投资回收期、盈亏平衡点、税后净利润等关键绩效。经经济分析,计算投资回报率为105.36%,投资回收期较低,为0.94年,可抵销原有投资。贴现累积利润(NPV)分析显示,在第三年实现了盈亏平衡。另一方面,在酯交换反应中使用磺化碳的装置,计算的投资回报率为14.02%,投资回收期为7.13年,第9年实现盈亏平衡。综上所述,无论从技术上还是经济上看,用CaO催化剂催化酯交换反应的生产厂都是最有前途的途径。

Process simulation and economic assessments for biodiesel production catalyzed by green Nanocatalysts

The biodiesel production catalyzed by naturally derived catalysts such as calcium oxide (CaO) and sulfonated carbon catalysts achieved high biodiesel yield at moderate operating conditions. However, very few studies were conducted to evaluate the economic feasibility of industrial-scale production of biodiesel catalyzed by both green catalysts of CaO and sulfonated carbon catalysts. The current study aims to assess the technical competency and economic feasibility of industrial-scale production of biodiesel catalyzed by two processes 1.) CaO catalyst and 2.) sulfonated carbon catalyst. Process simulations via Aspen Hysys were carried out to perform material and energy balances for both process configurations designed earlier with respect to the base catalyst (CaO) and acid catalyst (sulfonated carbon) used. Economic analysis was initiated after the equipment sizing and costing had been carried out. Total capital investment, total manufacturing cost, and key performances of the rate of return, payback time, breakeven point, and net profit after-tax rate were calculated for each process. Based on the economic analysis, the computed return on investment (ROI) is 105.36%, and it has a low payback period of 0.94 year to offset its original investment. The discounted cumulative profit (NPV) analysis shows that breakeven was achieved in the 3rd year. On the other hand, for the plant that utilizes sulfonated carbon in the transesterification reaction, the computed ROI is 14.02% with a payback period of 7.13 years, and the breakeven was achieved in the 9th year. In conclusion, the manufacturing plant of transesterification reaction catalyzed by CaO catalyst appeared as the most promising pathway either technically or economically.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
