摘要
为了探索高温焦炉荒煤气(COG)制还原气的实验条件,运用HSC-chemical软件中的最小吉布斯自由能法,对焦炉荒煤气非催化部分氧化过程进行了绝热等压热力学计算.研究了荒煤气初始温度、H_2O/COG和O_2/COG比,压力对反应体系平衡组成的影响,综合考虑了体系绝热反应温度,有效气体产率,有效转化率,能耗等因素,得出适宜的操作条件为初始温度600℃,O_2/COG,H_2O/COG分别为0.20,0.186左右,压力为常压或微负压.此时焦炉荒煤气转化率约为99%,绝热反应温度约为955℃,有效气体产率接近90%,平均产H_2约1.54mol/mol,增氢2.55倍.分析了H_2O/COG=0.186,O_2/COG变化时平衡产物的生成规律.
In order to explore experimental conditions of reduction gas yield from hot coke oven gas,COG,in non-catalytic oxidation process,adiabatic isobaric thermodynamic calculations were performed by using the Gibbs free energy minimization method of chemical software HSC.Considering adiabatic temperature,available gas yield rate,available conversion rate and energy consumption,the effects of operation parameters such as initial temperature,molar ratio of steam to COG,molar ratio of oxygen to COG,and pressure in t...
