    摘要:

    利用Aspen Plus軟件建立了加壓串行流化床生物質(zhì)氣化過程的模型,，并將模擬數(shù)值與試驗(yàn)結(jié)果相比較,，驗(yàn)證了模擬研究的可行性,。分別研究了氣化溫度Tg,、氣化壓力pg以及水蒸氣與生物質(zhì)的質(zhì)量比（S/B）對(duì)生物質(zhì)合成氣的成分、氫碳比,、氣化份額,、生物質(zhì)合成氣產(chǎn)率和生物質(zhì)碳轉(zhuǎn)化率等的影響。結(jié)果表明氣化溫度,、氣化壓力和S/B對(duì)生物質(zhì)氣化過程有很重要的影響,，適當(dāng)?shù)靥岣邭饣瘻囟群蜌饣瘔毫?duì)制取生物質(zhì)合成氣有利（Tg在800 ℃左右，pg在0.4MPa左右）,，合適的S/B在0.4左右,。

    Abstract:

    With Aspen Plus software, the simulation of the whole process of bio-syngas production from gasification via pressurized interconnected fluidized beds was carried out, and the model was validated by the comparison of simulation results and experimental results. The effects of gasification temperature (Tg), gasification pressure (pg) and steam to biomass ratio (S/B) on bio-syngas composition, H2/CO ratio, gasification proportion, bio-syngas yield, and carbon conversion were studied. The results showed that gasification temperature, gasification pressure and S/B had great influences on the biomass gasification process and the suitable gasification temperature and pressure was around 800℃ and 0.4MPa.
