摘　　要：用直径200mm的外热式固定床反应器,以城市生活垃圾中9种典型成分的混合物为实验物料,在300 ℃～700 ℃对其进行了低温热解的实验研究.结果表明,在其他条件相同的情况下,随着热解温度的提高,热解反应所需时间缩短;热解气的总产率、最大瞬时产率均增加;热解气的各成分随温度的升高呈现出不同的变化趋势;热解气的热值在600 ℃达到最大值,为15.13 MJ/m3,可满足民用燃气的要求.The low-temperature pyrolysis of the mixture of nine typical components from municipal household garbage has been studied from 300°C to 700°C using an externally heated fixed-bed reactor with 200 mm diameter. The results indicate that with increasing pyrolysis temperature, the duration of pyrolysis reaction reduces, however, the total yield of pyrolysis gas and the maximum instantaneous yield increases. At the same time, the proportion of each gas component presents different variations with increasing temperature. At 600°C the calorific value of the pyrolysis gas reaches the maximum, 15.13 MJ/m3, which meets the combustion standard for civil gas.
