| 摘 要： | 拟通过精馏法催化裂解工艺和酯化后处理工艺联用,制备低含氧量的替代柴油燃料油。采用自组装精馏法催化裂解反应装置,CaO催化剂,考察了催化裂解对裂解产物(裂解油)组分的影响,GC-MS和凝胶色谱分析显示:精馏法催化裂解工艺可有效控制裂解油的分子组成,降低平均相对分子质量。测定裂解产物的部分燃料油性能分别为:酸值59 mg/g,密度825 kg/m3、黏度4.07 mm2/s、热值41 kJ/g、冷凝点-43℃、冷滤点-22℃。裂解油经催化酯化后处理后,经FT-IR和GC-MS分析表明,其组成主要为碳链小于C24的烷烃、烯烃化合物,长链烃含量减少,C16以下的短链脂肪酸甲酯明显增多;酸值降至2.9 mg/g,羧酸含量显著降低,燃烧热值增大,进一步提高了燃料油品质和应用性能。

| Abstract: | Processes of pyrolysis and esterification post-treatment of tung oil have been studied to make diesel-like fuel with low oxygen levels.The catalytic pyrolysis reactions of tung oil was carried out in self-assembled distillation system,which showed the effects of pyrolysis on molecular components of pyrolytic product(pyrolytic oil).By GC-MS and SEC analysis,it was found that the fraction distribution of product was modified by pyrolysis.The acid value of pyrolytic products was 2.9 mg/g,the density was 825 kg/m3,the viscosity was 4.07 mm2/s,the gross calorific value was 41 kJ/g,the freezing point was-43 ℃,and the cold filter plugging point was-22 ℃.From the results of FTIR and GC-MS measurements,the esterification products were determined to consist of alkanes,with carbon chain below C24,fatty acid methyl ester of short chains below C16 and lower average molecular weight.The acid value of esterification products was 2.9 mg/g,the carboxylic acid content was significantly lower,and the burning heat value increased.The properties and applicability of products were also further improved. |
