Catalytic microwave pyrolysis of peanut shell (PT) and pine sawdust (PS) using activated carbon (AC) and lignite char (LC) for production of phenolic-rich bio-oil and nanotubes was investigated in this study. The effects of process parameters such as pyrolysis temperature and biomass/catalyst ratio on the yields and composition of pyrolysis products were investigated. Fast heating rates were achieved under microwave irradiation conditions. Gas chromatography-mass spectrometry (GC-MS) analysis of bio-oil showed that activated carbon significantly enhanced the selectivity of phenolic compounds in bio-oil. The highest phenolics content in the bio-oil (61.19 %(area)) was achieved at 300°C. The selectivity of phenolics in bio-oil was higher for PT sample compared to that of PS. The formation of nanotubes in PT biomass particles was observed for the first time in biomass microwave pyrolysis.
本研究采用活性炭（AC）和褐煤焦（LC）对花生壳（PT）和松木屑（PS）进行催化微波热解，以生产富含酚类的生物油和纳米管。考察了热解温度和生物质/催化剂比等工艺参数对热解产物产率和组成的影响。在微波辐射条件下实现了快速加热速率。生物油的气相色谱-质谱（GC-MS）分析表明，活性炭显著提高了生物油中酚类化合物的选择性。在 300°C 时，生物油中酚类含量最高（61.19%（面积））。与 PS 相比，PT 样品中生物油的酚类选择性更高。首次在生物质微波热解中观察到 PT 生物质颗粒中纳米管的形成。
