中文摘要:基于ASPEN PLUS平台利用气固反应动力学,在生物质热解气燃烧所产生的烟气气氛下,建立生物质热解气化模型。通过AKTS热动力学软件分析了生物质在模拟烟气(80%N2、17%CO2、3%O2)气氛下热解气化的反应动力学,并对比模拟值和实验值,验证模型的可靠性;对影响热解气化特性的气氛进行分析并确定反应釜数量。结果表明:基于ASPEN PLUS平台进行生物质气化模拟性能良好。生物质热解气化过程中,动力学参数活化能和指前因子随着反应的进行而变化;与氮气和氧气气氛相比,烟气气氛有利于CO产生,产气热值比实验值提高13倍。

Abstract:Based on the ASPEN PLUS platform, the biomass pyrolysis gasification model was established by using the gas-solid reaction kinetics in the flue gas atmosphere generated by the biomass pyrolysis gas combustion. The kinetics of pyrolysis biomass was analyzed by AKTS in simulative flue gas (80%N2, 17%CO2 and 3%O2). The simulation results were compared with the experimental values to verify the validity of the model, and the number of reactors was determined by analyzing the atmosphere influencing the pyrolysis gasification characteristics. The results showed that the simulation performance of biomass gasification based on ASPEN PLUS platform was favorable. The model was closer to the actual countercurrent flow reaction with the increase of the number of kettle. In order to ensure the accuracy of simulation, it was more appropriate to choose the number of reactors in series 4. During the process of biomass pyrolysis gasification, the activation energy (E) and the pre-exponential factor (A) of the kinetic parameters were not fixed values but changed with the increase of the reaction temperature. The pyrolysis gasification reaction did not follow a single reaction mechanism, which was composed of multiple steps. Compared with the nitrogen and oxygen atmosphere, the flue gas atmosphere was favorable for the production of CO. The calorific value of gas was increased by 1.3 times, which was mainly caused by the increase of volume of CO and CH4.

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.
