摘要：采用自组装裂解-精馏耦合精炼装置,以大豆油为原料考察了精馏柱温度(DT)、裂解反应釜温度、加料速度等反应条件对裂解产物性能的影响。结果表明,最佳反应条件为:精馏柱温度范围为320～350℃,裂解反应釜温度为480～500℃,滴加速度为35g/h。裂解所得产物密度825kg/m3,粘度4.0mm2/s,热值42MJ/kg,冷凝点-9℃,冷滤点-4℃,燃料性能较好。通过凝胶色谱和气质联用对裂解产物的分析表明,产物具有较低的平均分子量,主要成分为烷烃、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。
The catalytic cracking reactions of soybean oil had been studied. The effects of reaction conditions on properties of cracked products were investigated. The optimum conditions were obtained as follows, distillation tem- perature range （DT） of 320-350℃, cracking temperature of 480-500℃, and feed rate of 35g/h. The cracked products provided good performances of fuel as below, density of 825kg/m3, viscosity of 4.0mmE/s, heat value of 42MJ/kg, freezing point of -9℃ and the cold filter plugging point of -4℃. Furthermore, the products were ana- lyzed by GC-MS and SEC, showing the formations of alkanes, alkenes and carboxylic acid. The results showed that the cracked-oils possess low average molecular weight and similar physical and chemical properties of diesel oils.
