摘要:
作为清洁可再生的绿色能源,生物柴油的制备技术和生产工艺引起越来越多的关注。在超临界甲醇制备生物柴油工艺的基础上,为了降低生产成本、提高产品质量,文中利用实验室自制的盘管式反应器连续化制备生物柴油,通过考察稳定时间、反应温度和进料流量对产物产率的影响,发现在120 min后产率趋于稳定并达到最大值,其随着温度的增加、进料流量的减小而增大。同时,对超临界酯交换反应的热力学行为进行研究,计算溶解度参数,结果表明温度越高,反应物的溶解度参数越接近,越有利于反应进行。
Abstract:
The preparation technology and production process of biodiesel have drawn great attention. continuously. In this article, in order to reduce the production cost, improve the production quality and benefit the industrial production, the laboratorial home-made coil reactor was used for continuous production of biodiesel based on the supercritical methanol production process of biodiesel. The influence of stability time, reaction temperature and feed flow rate on the yield of biodiesel was observed, showing the yield tended to be stable and attained the maximum after 120 min. The yield increased with the increase of temperature and the decrease of the feed flow rate. At the same time, the thermodynamics behavior was studied, and the solubility parameters were calculated. The higher the temperature, the closer the solubility parameters of reactants, and easier to continue the reaction.
