摘　　要：为探索生物油共裂解制烃的特性和机理，以愈创木酚作为模型化合物，在550℃下通过HZSM-5进行催化热裂解。实验证实催化共裂解对愈创木酚的脱氧作用，从而使烃类产物的收率得以显著提高。通过考察正丁醇、正丁酮、正丁酸同愈创木酚的共裂解效果，表明以正丁醇为代表的醇类是3类中最优的共裂解物质。在此基础上，考察以C1-C6醇类作为共裂解物质对反应的影响，表明低碳数醇类同愈创木酚共裂解时更容易生成水，对愈创木酚的脱氧效果差，而高碳数醇类在反应时更易生成积碳，但烃类收率较高。不同碳数的醇类中，正戊醇是最优的共裂解物质。In order to explore the characteristic and mechanism of bio-oil hydrocarbon through the method of co- pyrolysis, guaiacol was used as bio-oil model compound. In this paper, the co-pyrolysis process was taken under 550 ℃, in the presence of HZSM-5. The experiments confirm that the catalytic co-pyrolysis process has benefit in the deoxidization of guaiacol, which makes a high yield of hydrocarbon. Though investigating guaiacol co-pyrolysis with N- butanol, N, butanone, and N-butyric acid, we know that N-butanol is the best in all the three co-pyrolysis materials. Additionally, alcohols of C1-C6 was also co-pyrolysed with guaiacol. The results indicate that alcohols of low carbon number are more likely to produce water, and they are not so benefit to the deoxidation of guaiacol. On the contrary, alcohols of high carbon number could result in high carbon deposition, however, they can improve the yield of hydrocarbons. N-pentanol is the best in all the co-pyrolysis materials.
