摘要
基于Aspen^(plus)建立生物质油纯氧气流床气化工艺模型,通过灵敏度分析初步探讨工艺条件、不同氧含量和生物质油等参数对气化结果的影响,并对不同气化介质的气化结果进行比较。模拟研究表明:氧气当量系数ER约为0.37,气化温度可达约1280℃,生物质油纯氧气化有效气成分可达约90%。在无外部供氧条件下,合成气的CH_4含量过高;随O_2在空气中比例降低,CH_4含量成倍上升;水蒸气的加入有利于抑制CH_4生成。
To investigate the technical feasibility of bio-oil entrained flow gasification and seek for the optimal technical conditions, a model was built by Aspen^pnis . Sensitivity analysis with O2 equivalence ratio, oils of different oxygen content and gasification agents were performed. The conclusions were derived : when ER at around 0.37, gasification temperature can reach 1280℃, effective gas composition can reach up to about 90% ; oxygen-free process produces a high level of CH4; with O2 proportion reducing in the air, CH4 content increases rapidly; water vapor added can effectively control CH4 generation.
