Simulation Study of Biomass Gasification [PDF]
, 2016 生物质气化是生物质利用过程中热效率较高的一种方法，同时也是一种十分重要的可再生能源利用方式。本文采用AspenPlus模拟软件，结合吉布斯自由能最小原理，建立了生物质气化反应器模型，模拟研究了不同操作参数对气化结果的影响，同时对三种气化剂下的气化结果进行了对比分析。 在三种气化剂的模拟结果中，同一操作参数对气化结果的影响有一定共通性：（1）随着气化温度的升高(600～900℃)，一氧化碳体积分数升高，二氧化碳和甲烷体积分数降低，但氢气体积分数变化不大；气体的热值升高（700℃以上），气体产率先升高后降低，
