【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。
