摘　　要：利用Fasctsage 6.4软件对褐煤化学链气化的合成气模型化,模拟计算了对磷石膏载氧体的化学链气化制取合成气的过程,并对磷石膏载氧体的褐煤化学链气化的反应机制进行研究探讨。结果显示,H_(2)和CO是褐煤化学链气化合成气中的两种主导产品。升高气化温度将会对气化过程产生积极影响;外加水蒸气和CO_(2)气氛下同样可以提高合成气的产量。反应温度在950℃左右较为适宜;载氧体的使用可以使合成气的产率得到显著提升。Simulation of syngas production from lignite gasification with phosphogypsum was carried out with Fasctsage 6.4 software,the reaction process of Chemical-Looping Gasification of lignite for syngas was investigated.The results showed that H_(2) and CO were the primary products in the syngas of lignite chemical looping gasification.The increase of temperature was beneficial to gasification process and water vapor and CO_(2) atmosphere also could improve the production of the syngas.The optimal gasification temperature was around 950℃.The study showed that the existence of oxygen carrier could improve the yield of syngas.
