A comparison of two processes of the synthesis of 1,1-diethoxybutane (DEB) based on parametric analysis using Aspen Plus simulation has been investigated. DEB is an acetal which is a promising bio-based additive for biofuels and their blends with conventional fuels. The thermodynamic limitations due to reversibility of the reaction can be overcome by continuously removing the by-product water. The simulation and a parametric study of two different synthesis processes of DEB using a catalytic fixed-bed reactor and distillation column are described. The process with three reactors and three separators in series showed better results with respect to reactor temperature, productivity of DEB, and stages of distillation column than the one with a single reactor and separator.

在固定床反应器和蒸馏塔中合成 1,1-二乙氧基丁烷的参数分析‡

已经研究了基于使用 Aspen Plus 模拟的参数分析合成 1,1-二乙氧基丁烷 (DEB) 的两个过程的比较。DEB 是一种缩醛，是一种很有前途的生物基添加剂，可用于生物燃料及其与传统燃料的混合物。由于反应的可逆性导致的热力学限制可以通过连续去除副产物水来克服。描述了使用催化固定床反应器和蒸馏塔对两种不同的 DEB 合成工艺进行模拟和参数研究。与具有单个反应器和分离器的工艺相比，具有串联的三个反应器和三个分离器的工艺在反应器温度、DEB产率和蒸馏塔级数方面显示出更好的结果。
