In the present study, bio-oil and biochar have been produced from microwave-assisted catalytic pyrolysis of corn stover (CS). The effects of microwave power (MWP) and mixing of sodium carbonate as a catalyst at different ratios have been examined. Both MWP and the catalyst improved the heating and increased the maximum temperatures of pyrolysis process. Rise in MWP increased the gas yield but decreased the biochar yield, while the bio-oil yield was not significantly affected. The use of catalyst increased the bio-oil yield and enhanced its properties. Increase in the ratios of catalyst from 10% to 30%, did not contribute a significant effect either on the yield or on the properties of the products. The water content in bio-oil was found to be in the range of 53.09–73.79%, while the minimum viscosity was observed to be 3.31 mPa s. The maximum higher heating value (HHV) of bio-oil and biochar were 13.17 MJ/kg and 29.77 MJ/kg respectively. The bio-oil samples were characterized chemically by a gas chromatography-mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FTIR). Most of the chemical group compounds in the bio-oil were identified to be alcohol, phenols, alkynes, acids, and aromatic. The net energy recovery from the raw CS was in the range of 28.29–42.97%.

在本研究中，玉米秸秆（CS）的微波辅助催化热解制备了生物油和生物炭。研究了微波功率（MWP）和碳酸钠作为催化剂以不同比例混合的影响。MWP和催化剂都改善了加热并提高了热解过程的最高温度。MWP的增加增加了气体产量，但降低了生物炭产量，而生物油产量没有受到明显影响。催化剂的使用增加了生物油的产率并增强了其性能。催化剂比例从10％增加到30％，对产率或产物性能没有明显影响。发现生物油中的水含量在53.09–73.79％的范围内，而最低粘度为3.31 mPa s。生物油和生物炭的最高最高发热量分别为13.17 MJ / kg和29.77 MJ / kg。通过气相色谱-质谱（GC-MS）和傅里叶变换红外光谱（FTIR）对生物油样品进行化学表征。生物油中的大多数化学基团化合物被确定为酒精，酚，炔烃，酸和芳香族化合物。原始CS的净能量回收率在28.29-42.97％之间。
