| 摘 要： | 为进一步优化焦炉煤气非预混燃烧直接制备合成气的工艺参数,对焦炉煤气在贫氧条件下发生非预混燃烧的过程进行数值模拟研究,得到了反应器内温度及产物组成分布的详细分布状况.模拟结果表明,反应在靠近氧气入口的区域内发生.从数值模拟的结果来看,反应器壁温对反应结果有非常重要的影响:提高反应器壁温有利于提高合成气的选择性,但是煤气中甲烷的转化率有所降低.因此,反应器壁温是能够控制本工艺总体反应效果的重要参数,工艺优化过程中应该特别注意.

| Abstract: | Non-premixed combustion of coke oven gas under low oxygen condition was investigated through computational fluid dynamic(CFD)simulation coupled with radiation heat transfer.Temperature profile and product distribution in reactor were obtained from simulation.Calculated temperature profile indicates that oxygen react strongly with coke oven gas in region near the oxygen nozzle and the temperature in this region increase sharply.Noticeable influence of reactor wall temperature on product distribution could be... |
