中文摘要:采用耐驰同步热重分析仪,对HZSM—5催化提质前后焦油的理论燃烧特性和动力学进行分析。结果表明,催化提质前、后焦油燃烧过程约分为4个阶段:轻质有机物挥发段、挥发分燃烧段、难挥发组分燃烧段和残留物燃烧阶段,原始焦油前2个阶段失重率约为75%,而提质焦油失重率约为90%。随着升温速率增加,提质焦油最大燃烧速率显著增加,燃烧稳定性明显提高。根据热重曲线计算动力学参数,提质焦油的活化能的变化与热重试验结果符合,明显降低。应用热红外对焦油的燃烧烟气进行燃烧过程分析,气体产物生成主要分为241~380℃、380~500℃和500~600℃3个阶段。

Abstract:Combustion characteristics and kinetics of bio-tar before and after catalytic upgrading were studied on a thermogravimetric apparatus. The results showed that the combustion process was divided into four stages: light organics volatilization, volatilization content combustion, less volatilization content combustion and residue combustion. Weight loss in the first two stages of raw tar was about 75%, whereas that of tar after upgrading was about 90%. With the increasing heating rates, weight loss rate increased heavily along with significantly enhanced combustion stability. According to thermogravimetric curve calculation kinetic parameters, activation energy of upgrading tar was lowered and in agreement with that from TG analysis. The gas from combustion was analyzed by Fourier transform infrared spectroscopy method, which showed the gaseous products generated in three phases of 241~380℃, 380~500℃ and 500~600℃.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
