摘要： 以大豆油为原料,考察了间歇式反应工艺,旋转锥式反应工艺和精馏反应工艺3种裂解工艺对裂解产物性能的影响,并探讨了多种催化剂的催化裂解效果。结果表明,优选反应条件为:催化剂质量分数 5 % 精馏温度320~350 ℃,裂解温度460~480 ℃,滴加速度 35 g/h。在碱性催化剂Na2CO3的参与下,利用精馏反应工艺裂解大豆油产物的分子组成得到优化。通过红外光谱、气质联用和凝胶色谱对裂解产物的分析表明,产物具有较低的平均相对分子质量,主要成分为C24以下的烷烃、烯烃、醛、羧酸等。从化学组成及燃料性能来看,裂解产物的性质与石化柴油相近。

Abstract: Three types of triglyceride cracking processes i.e. batch process, rotating cone process and distillation process was studied. Several kinds of catalysts were compared with each other. It was found that the optimum reaction conditions are as follows: mass fraction of catalyst 5%, distillation temperature 320-350 ℃, cracking temperature 460-480 ℃ and feed rate 35 g/h. The fraction distribution of product was modified using alkalinic catalyst such as Na2CO3 and distillation process. From the results of FT-IR, GC-MS and SEC measurements, the products were determined to be consisted of alkanes, alkenes and carboxylic acids with carbon chain below C24 and lower average molecular weight. The physical and chemical properties of products were also detected to be close to those of petroleum-based fuels.

Key words: catalytic cracking, processes, soybean oil, renewable liquid fuel CLC number:TQ517
