摘要

  • 摘要: 基于Aspen Plus模拟平台，运用吉布斯能最小化原理，以天然气全氧燃烧尾气（后续称为烟气）作为气化剂，选取反应温度和烟气流量与生活垃圾量比（E/M）作为影响因素，气化炉温度变化范围为400~1 500℃，E/M范围0~3.0，对几种典型生活垃圾（木屑、纸屑、塑料、橡胶和厨余）气化进行模拟计算。模拟结果表明，以烟气作为生活垃圾气化剂，可制备富氢产品气，产品气为中热值燃气。温度在800℃左右时，H2的体积分数达到峰值46.75%，反应温度大于800℃时，反应温度的增加对提升产品气的热值、CO的含量有一定作用，但H2的含量和产品气产率有所下降，反应温度过高增加气化的能源投入，反应温度应控制在800~1 000℃范围。高温烟气的过量导致产品气热值和品质下降，E/M宜控制在0.4~1.0区间范围。
    Abstract: Based on Aspen Plus, a method of minimizing Gibbs free energy was developed. When the gasifier temperature was between 400 and 1 500℃ and E/M (flow rate of exhaust to municipal solid waste (MSW)) was between 0 and 3.0, the gasification performances of several typical forms of MSW (wood, paper, plastics, rubber, and food waste), using oxy-fuel combustion products with natural gas as the gasification agent, were analyzed. The simulation results indicated that hydrogen-rich product gas can be produced using flue gas as the garbage gasification agent, and its heating value was in the medium-heating range. When the temperature was approximately 800℃, the molar volume of H2 reached 46.75%. When the reaction temperature was higher than 800℃, the product gas heat value and CO content increased with increasing reaction temperature, but H2 content and productivity decreased. Therefore, the reaction temperature should be in the 800 to 1 000℃ range for the energy input. High-temperature exhaust gas as a gasification agent should not be excessive, and E/M should be in the 0.4 to 1.0 range.
