摘要: 本文基于化学链气化原理，得到合成气的有效成分为一氧化碳和氢气。利用HSC模拟软件，模拟气化温度、压力以及配比对产生合成气成分及浓度的影响。模拟结果表明，随温度升高，CO和H2各占比不断增大；合成气中CO和H2各占比随着压力增加而不断降低；CO + H2占比随着水蒸气/载氧体增大明显降低；随着载氧体/生物质增大，H2比例逐渐下降，CO比例显著提高，CO2和CH4比例略有提高。则该气化最佳控制参数为：温度1000℃，压力1 atm，水蒸气/载氧体为0.5，载氧体/生物质为0.10。
Abstract: Based on the principle, this paper adopts gasification and air reactors to produce the syngas with CO and H2 as the main compositions. Using HSC simulation software, the effects of reaction temperature and pressure, ratio of H2O to oxygen carrier, ratio of oxygen carrier and biomass on the composition and concentration of the syngas were simulated. The results show that the volume fraction of CO and H2 increases with the increasing of gasification reaction temperature. The CO and H2 in the syngas decrease gradually with the increasing of gasification reaction pressure. As the molar ratio of H2O to oxygen carrier increases, the content of CO + H2 decreases significantly. As the molar radio of Mn2O3 to biomass increases, the content of CO increases significantly, the content of H2 decreases gradually, and the contents of CH4 and CO2 increase slightly. The parameters are determined as follows: gasification temperature is 1000˚C; gasification pressure is 1 atm; the molar radio of H2O to oxygen carrier is 0.5; the molar radio of oxygen carrier to biomass is 0.10.
