摘　　要：滴流床反应器是一种气-液-固三相催化反应器,气液并流向下或逆流而上的方式,借助固态催化剂床层,被绝大部分石油化工企业所运用,同时石油炼制、精细化学工程、环境治理工程、污水处理工程等项目应用也较为广泛。滴流床反应器在特殊领域以及特定需求的催化要求下有着无可替代的竞争优势。现有的氯代碳酸乙烯酯催化反应基本上为反应釜式反应器,对于光催化反应,由于光能量的损失,对内部反应影响较大,易形成过度化反应,进而影响产品的含量以及杂质数量。氯代碳酸乙烯酯是气液式反应,比较适合滴流床式反应装置,文章对滴流床式氯化反应进行了相关研究,通过不断改进实验方案,以得到最优实验效果。Trickle bed reactor is a gas liquid solid thee-phase catalytic reactor,which is used by most petrochemical enterprises with the help of solid catalyst bed in the way of gas-liquid concurrent flow down or countercurrent flow up.At the same time,petroleum ref ining,f ine chemical engineering,environmental treatment engineering,sewage treatment engineering and other projects are also widely used.Trickle bed reactor has irreplaceable competitive advantages in special f ields and under the catalytic requirements of specif ic needs.The existing catalytic reaction of vinyl chloride carbonate is basically a reactor type reactor.For the photocatalytic reaction,due to the loss of light energy,it has a great impact on the internal reaction,which is easy to form an excessive reaction,thus affecting the product content and the amount of impurities.Vinyl Chlorocarbonate is a gas-liquid reaction,which is more suitable for trickle bed reactor.In this paper,the trickle bed chlorination reaction has been studied,and the experimental scheme has been continuously improved to obtain the optimal experimental effect.
