The effects of different activated carbon (AC) catalysts based on various carbon sources on products yield and chemical compositions of upgraded pyrolysis oils were investigated using microwave pyrolysis of Douglas fir sawdust pellets. Results showed that high amounts of phenols were obtained (74.61% and 74.77% in the upgraded bio-oils by DARCO MRX (wood based) and DARCO 830 (lignite coal based) activated carbons, respectively). The catalysts recycling test of the selected catalysts indicated that the carbon catalysts can be reused for at least 3-4 times and produced high concentrations of phenol and phenolic compounds. The chemical reaction mechanism for phenolics production during microwave pyrolysis of biomass was analyzed.
采用微波热解法对道格拉斯冷杉锯末颗粒进行研究，考察了不同来源的活性炭（AC）催化剂对热解油产率和化学组成的影响。结果表明，得到了高含量的酚类物质（通过 DARCO MRX（木质基）和 DARCO 830（褐煤基）活性炭升级后的生物油中分别为 74.61%和 74.77%）。对所选催化剂的催化剂回收试验表明，碳催化剂可至少重复使用 3-4 次，并产生高浓度的酚类和酚类化合物。分析了生物质微波热解过程中酚类物质生成的化学反应机理。
