| 摘 要： | 以纤维素为原料,以自制的不同硅铝比ZSM-5(38)/Al-MCM-41微-介孔复合分子筛为催化剂,在固定床反应器上进行了催化热解实验。采用XRD表征分子筛,采用GC-MS分析生物油成分,考查了催化剂的改变对生物质热解产物及生物油成分的影响。实验结果表明:添加催化剂后,生物油产率降低,且其含水率也有所增加。与未添加催化剂相比,生物油中D L-2,3-丁二醇有明显提高。其中,ZSM-5(38)/Al-MCM-41(20)最有利于苯酚、愈创木酚(2-甲氧基-苯酚)的生成。此外,这几种催化剂均有利于小分子化合物的生成,其中,ZSM-5(38)有利于C4~C5化合物的生成,微-介孔复合分子筛则有利于C6~C8化合物的生成。

| Abstract: | Pyrolysis of cellulose with different catalysts has been conducted in a fixed-bed reactor.Micro-mesoporous composite molecular sieves of ZSM-5(38)/Al-MCM-41 with different Si/Al ratios were prepared under hydrothermal conditions.With powder X-ray diffraction(XRD),the catalyst samples were characterized.GC-MS was used to analyze the bio-oil composition.The effects of catalysts on the pyrolysis product yields were investigated and the results were compared with the results of experiments performed without cat... |
