摘　　要：通过对EO催化水合乙二醇过程的物料衡算和热量衡算,建立了反应器计算的简单数学模型,分析了水撤热和循环物料撤热两种方法对反应器热点温度控制的效果,计算了反应过程中温度和反应物转化率随管长变化的规律。根据对反应器热点温度分析表明:EO催化水合乙二醇的过程,由于催化剂的加入,使反应以很快的速率进行且转化率可达到90%左右,同时放出大量的反应热,此时采用水撤热和循环物料控制的方法,其热点温度相近。结合能量利用并考虑反应器的设计、制造和操作因素,建议采用循环物料控制方法。By calculating the material balance and heat balance in EO catalytic hydration process,a simple mathematical model was established for reactor calculation,the effect of two heat removal methods using water and circulating material as cold media respectively in controlling the maximum temperature of reactor was analyzed,and the variations of temperature and reactant conversion with tube length during the reaction were calculated.The analysis on maximum temperature of reactor shows that in EO catalytic hydration process,the raw materials can be quickly converted with a conversion rate of 90%in the presence of catalyst,and a large amount of reaction heat can be released.At this time,the maximum temperature of heat removal by water is close to that of heat removal by circulating material.Taking energy utilization and the design,manufacture and operation of reactor into consideration,the heat removal by circulating material is recommended.
