精馏法催化大豆油裂解制备可再生燃料油
DOI: 10.3969/j.jssn.1000-2006.2011.04.018, PP. 87-90
Keywords: 催化裂解,精馏工艺,大豆油,可再生燃料
Abstract:
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35g/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825kg/m3，黏度4？0mm2/s，热值42mj/kg，冷凝点-9℃，冷滤点-4℃,具有较好燃料性能。
