【摘要】：基于Aspen Plus模擬平臺,運用吉布斯能最小化原理,以天然氣全氧燃燒尾氣(后續(xù)稱為煙氣)作為氣化劑,選取反應(yīng)溫度和煙氣流量與生活垃圾量比(E/M)作為影響因素,氣化爐溫度變化范圍為400~1 500℃,E/M范圍0~3.0,對幾種典型生活垃圾(木屑、紙屑、塑料、橡膠和廚余)氣化進行模擬計算。模擬結(jié)果表明,以煙氣作為生活垃圾氣化劑,可制備富氫產(chǎn)品氣,產(chǎn)品氣為中熱值燃氣。溫度在800℃左右時,H2的體積分數(shù)達到峰值46.75%,反應(yīng)溫度大于800℃時,反應(yīng)溫度的增加對提升產(chǎn)品氣的熱值、CO的含量有一定作用,但H2的含量和產(chǎn)品氣產(chǎn)率有所下降,反應(yīng)溫度過高增加氣化的能源投入,反應(yīng)溫度應(yīng)控制在800~1 000℃范圍。高溫?zé)煔獾倪^量導(dǎo)致產(chǎn)品氣熱值和品質(zhì)下降,E/M宜控制在0.4~1.0區(qū)間范圍。
[Abstract]:Based on the Aspen Plus simulation platform, using Gibbs energy minimization principle, natural gas total oxygen combustion tail gas (later called flue gas) was used as gasifier, and reaction temperature and flue gas flow ratio (E / M) were selected as the influencing factors. The temperature variation range of gasifier is 400 ~ 1 500 鈩，
