| 摘 要： | 对生物质喷动流化床快速裂解油进行催化裂解精制，在氧气气氛，不同升温速率下对精制前后的生物质油和精制油进行TG—DTA分析，对生物质油精制前后的燃烧性能和动力学进行了分析和比较。结果表明：精制后比精制前挥发所需能量降低了10．02kJ／mol；燃烧活化能由原来的173．64kJ／mol降低到80．95kJ／mol，这说明精制后的精制油大大降低了燃烧所需的活化能，提高了油的可燃性，使得生物质油更容易燃烧。

| Abstract: | In order to improve the quality, bio-oil from pyrolysis of biomass in spouted fluidized reactor was further upgraded by catalytic cracking procedure. Thermal weight loss curves of pyrolysis bio-oil and upgraded bio-oil were determined by TG-DTA method in the oxygen atmosphere at different superheating rates, and combustion kinetic parameters were calculated. The results show that the volatilization energy decreases from 38.23 kJ/mol to 28.21 kJ/mol and the activity energy significantly decreases from 173.64 kJ/mol to 80. 95 kJ/mol after upgrading. The upgraded bio-oil is more combustible in comparison to pyrolysis oil. |
