中文摘要:对未经粉碎的棉秆进行了直接热解炭化实验研究。研究表明,未经粉碎的棉秆在热解温度400℃时进行热解炭化后,生成的秸秆炭的比例最高,且秸秆炭中的固定碳含量最高。在棉秆热解过程中,随着反应温度的增加,热解固体产物质量不断减小;热解温度高于400℃以后,随着反应温度的增加,固体产物中固定碳含量开始下降。通过正交试验得到了最优组合的热解工艺参数为:热解温度400℃,升温速率5℃/min,保温时间2 h。得炭率可达49.98%。

Abstract:Biomass pyrolysis is a high value-added process of biomass conversion. The direct pyrolysis experiments of no crushed cotton stalks were conducted. The results showed that the solid product and fixed carbon (FC) content were maximum when pyrolysis temperature was in 400℃. As the pyrolysis reaction proceeded, the higher temperature increased and the solid products reduced, and the ash content in the products increased accordingly, which led to a decrease in fixed carbon (FC) content after 400℃. In order to determine the optimum technological parameter of pyrolysis, an orthogonal experiment was conducted.The maximum product yield of 49.98% was obtained with 5℃/min of heating rates, 400℃ of optimum pyrolysis temperature, and 2h of holding time.

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.
