摘要:对白松木热解焦油进行简单蒸馏,利用GC/MS色谱技术对馏分进行分析,发现焦油中各馏分主要组成为苯酚及其同系物和杂环化合物,且其中甲氧基苯酚及其同系物在蒸馏中是作为共沸物存在。在氮气氛围下,对焦油及其馏分进行热重分析得到的热重曲线可划分为两个阶段。以此为基础,利用Coats-Redfern方法建立动力学模型,计算动力学参数,结果表明焦油及其馏分的热解过程可用一级反应表示。
The composition of tar distillations gained by simple distillation was analyzed with GC-MS analysis tech- nology. The main component of all distillations is phenol and its homologue and heterocyclic compounds, in which guaiaeol and its homologue are existed as azeotrope. Under nitrogen atmosphere, the tar pyrolysis behavior was in- vestigated with different heating rates of 5, 10, 20, 30℃/min as same as its distillations with the heating rate of 10℃/min. The kinetic method of Coats-Redfern was used to analyze the TG data to identify reaction parameters which reflect reaction mechanism . And the results show that the reaction can be well described by first reaction order and two stages model.
