【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。更多还原

【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 super-heating 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.更多还原
