摘要
论文利用实时监测反应装置,模拟采空区遗煤在低温下的氧化过程。发现采空区CO释放速率随氧化时间的增加表现出明显的阶段性,并利用数据拟合方法找出CO的产生速率与时间的函数关系式。同时,通过实验对比研究证实,CO的释放速率除了受到氧气浓度和煤体表面活性位点的影响外,主要还是由于煤氧化产生抑制反应的氧化产物。
The paper simulated the low temperature oxidation process of coal in goaf,using real- time monitoring device.As oxidation time increased,the CO releasing rate showed obvious stages. A function relation between CO generating rate and time was determined, applying data fitting method. And comparison with the experimental results showed that,besides oxygen concentration and surface active sites of coal,oxidative product produced in coal oxidation is the main influencing factor for CO releasing rate.
