Abstract
利用HSC-Chemistry软件平台对以高温转炉熔渣为热载体的CH_4/CO_2/H_2O混合气体反应产物进行了热力学模拟计算,比较渣和水蒸气的反应、二氧化碳重整甲烷和水蒸气重整甲烷三个反应的AG和反应平衡常数K随温度的变化趋势。结果表明,甲烷重整和炉渣制氢这两类反应对炉渣热利用的温度段并不重合,可望通过这两个反应实现转炉熔渣余热的梯级高效利用。研究了以1923 K的转炉熔渣为载热体的甲烷重整反应,炉渣初始量为1000kg时,混合气体组分对各物质平衡转化率的影响。结果显示,958 K,CO_2和CH_4的初始量分别为15.38和6 kmol时,二者的平衡转化率分别为80%和83%。提高CO_..
