中文摘要:为研究旋转床反应器在不同载气条件下的秸秆生物质热解影响,在无载气、以尾气作为载气、以N2作为载气的情况下,进行了秸秆生物质在旋转床反应器中的热解反应。分别收集了生物炭、生物油以及合成气,进行了产量测算;对生物炭进行了热值与元素分析,对生物油进行了热值、含水率和元素分析;分析了合成〖JP2〗气有机物组成与含量。结果表明:通尾气能够减少生物炭产率,增加生物油产率,并且生物炭的热值、含碳量较高,分别为22.99MJ/kg、51.24%;生物油的含水率降低30.45%、有机物质量分数升高11.11%,但是生物油的热值下降,合成气中轻质有机物质量分数最高,为67.04%;尾气能够更加快速带走热解气或者参与热解的二次反应,生物质反应最充分,能够增加H的活性,减少水含量,但是无法去除氧元素,氧元素保留在生物油中;通N2能够减少生物炭产率,增加生物油产率,并且生物炭的热值较高,为22.28MJ/kg,含碳量较高,为55.86%,生物油的含水率和有机物含量变化不大,但是生物油的热值升高到12.25MJ/kg;合成气中轻质有机物质量分数最小,为64.07%;通N2能够减少热解二次反应的发生,热解气能够快速离开反应器。

Abstract:In order to study the influence of straw biomass pyrolysis in a rotating bed reactor under different carrier gas conditions, including no carrier gas, the tail gas and N2, biomass pyrolysis was tested based on the reactor. The bio char, bio oil and syngas were collected respectively, and the yield rates were calculated. The biochar’s calorific value and elements were analyzed; bio oil’s calorific value, water content and elements were analyzed; the syngas’ composition and content of organic compounds were analyzed by using gas chromatography. Passing the tail gas can reduce the generation of bio char, increase the production of bio oil, and the higher calorific value of bio char was, the higher carbon content was. The water content of bio oil was decreased, and organic matter content was increased. But when the calorific value of bio oil decreased, the content of light organic matter was the highest in syngas. The tail gas can take away pyrolysis gas more quickly or participate in the pyrolysis of two time reaction. Biomass react was the most adequate, and tail gas can increase the activity of H; reduce water content, but no way to remove oxygen elements, so the oxygen elements retained in the bio oil. Nitrogen can reduce production of biochar, increase bio oil production and calorific value, and change a little carbon content of biochar, bio oil moisture and organic matter content, but the calorific value of the bio oil greatly increased; the light organic matter content in syngas was the least. Nitrogen can reduce two time reaction and pyrolysis gas can quickly leave the reactor.

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.
