| 摘 要： | 用Fluent软件对焦炉煤气非催化部分氧化制取合成气的反应器内的温度场、浓度场和平衡气体组成进行了数值模拟.结果表明,氧气与焦炉煤气比是决定气化温度和出口合成气成分的关键.随着氧气与焦炉煤气比的增加,气化温度升高.在氧气与焦炉煤气质量比为0.14时,反应器出口的有效气体(H2+CO)含量达到最大值,焦炉煤气中的CH4几乎完全转化.在距反应器喷嘴0.05 m处反应器内达到了最高温度3 300 K,在0.1 m处H2和CO及CO2均达到平衡,CH4在该点降到最低点.

| Abstract: | The temperature field,concentration field and equilibrium gas composition in reactor which is used to produce syngas by the method of non-catelytic partial oxidation for COG were simulated by the software Fluent.The results show that the oxygen to COG mass ratio is a key factor to deciding the gasification temperature and syngas composition at the export.By the increasing of the ratio,the gasification temperature improves also.When the ratio is 0.14,the content of effective gas(H2+CO)reaches to the maximum,... |
