摘要: 以Ni-Co-Pd/γ-Al2O3为催化剂,在固定床反应器中研究了小球藻热裂解油的催化加氢精制。在较低加氢压力(2×106 Pa)下考察了加氢温度和氢油比(体积比)对精制生物油的含水率、热值、运动黏度和十六烷值等参数的影响,并对加氢前后油品进行了元素分析和GC-MS分析。结果表明,在2×106 Pa压力下,氢油比为120:1,温度为300 ℃时,精制油收率达89.6%,热值和十六烷值较加氢前分别增加了17.94%和71.2%,黏度下降66.32%。元素分析和GC-MS分析表明,精制生物油的H/C原子比由1.55提高至1.97,氧、氮、硫含量明显降低,脱氧率达到80.46%。精制油中的有机酸、酯、酮、醛的含量明显降低,烷烃和醇醚含量明显增加。
