中文摘要:以间歇式酯交换反应釜为对象,探讨了本底压力和温度等参数对釜内水热平衡状态的影响。通过建立三维温度-压力场分析模型,确定了釜内高压水热状态控制方程并实现超临界状态反应条件优化。在此基础上进行了以规模化养殖微藻为原料制备生物柴油的实验研究和油品分析。结果表明,以小球藻为原料的生物柴油产出率明显高于其他藻种。超临界反应条件的引入可使直接酯交换反应生物柴油产率提高近一倍。油品具有与0号柴油几乎相同的碳氢质量比、热值和密度等理化性能。

Abstract:Taking intermittent high-pressure transesterification reactor as object, the influence of background pressure and temperature on thermal equilibrium state of the water were discussed. Through establishing 3-D temperature-pressure field analysis model, the high-pressure hydrothermal state control equation was determined and supercritical state reaction condition was optimized. On this basis, the experimental study on biodiesel prepared with large-scale aquaculture microalgae as raw materials was carried out and the oil quality was analyzed. The results indicated that the output rate of biodiesel prepared with chlorella was evidently higher than that of other types of algae. The introduction of supercritical state reaction condition almost doubled the output rate of biodiesel and the oil quality had nearly the same carbon/hydrogen mass ratio, calorific value and density with the 0# diesel.

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.
