摘要：采用自组装的裂解精炼装置,以大豆油为原料考察了精馏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320~350℃,裂解反应釜温度480~500℃,大豆油滴加速度为35 g/h。通过红外光谱（FTIR）、气质联用（GC-MS）和凝胶色谱（SEC）对裂解产物的分析表明,产物具有较低的平均分子质量,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,裂解所得产物密度825 kg/m3,黏度4.0 mm2/s,热值42 MJ/kg,冷凝点-9℃,冷滤点-4℃,具有较好燃料性能。
The catalytic cracking reactions of soybean oil have been studied using a self-assembled distillation apparatus,and the optimal technological conditions were obtained as follows： the distillation temperature 320—350 ℃,cracking temperature 480—500 ℃,and adding rate of soybean oil 35 g/h.The fraction distribution of product was modified by the basic catalyst such as Na2CO3 and distillation process.It was known from the analysis results of FTIR,GC-MS and SEC that the cracked products mainly consisted of alkanes,alkenes,aldehyde,and carboxylic acid.Furthermore,the cracked-oil had a low average molecular weight,and had similar physical and chemical properties comparing to those specified for petroleum-based fuels.The properties of the cracked oil were measured as follows： density of 825 kg/m3,viscosity of 4.0 mm2/s,calorific value of 42 MJ/kg,freezing point of-9 ℃,and cold filter plugging point of-4 ℃.
