Catalytic microwave pyrolysis of biomass using activated carbon was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. The high concentrations of phenol (38.9%) and phenolics (66.9%) were obtained at the temperature of 589 K, catalyst-to-biomass ratio of 3:1 and retention time of 8 min. The increase of phenol and its derivatives compared to pyrolysis without catalysts has a close relationship with the decomposition of lignin under the performance of activated carbon. The concentration of esters was also increased using activated carbon as a catalyst. The high content of phenols obtained in this study can be used either directly as fuel after upgrading or as feedstock of bio-based phenols for chemical industry.
采用活性炭对生物质进行催化微波热解，以确定热解条件对苯酚和酚类收率的影响。在温度为 589 K、催化剂与生物质的比例为 3:1 和保留时间为 8 min 的条件下，可获得高浓度的苯酚（38.9%）和酚类（66.9%）。与无催化剂的热解相比，苯酚及其衍生物的增加与活性炭作用下木质素的分解密切相关。使用活性炭作为催化剂也会增加酯的浓度。本研究中获得的高含量苯酚可在升级后直接用作燃料，也可用作化工用生物基苯酚的原料。
