摘　　要：以实验研究结果为基础,建立了反应吸附强化焦炉煤气水蒸汽重整制氢(ReSER-COG)工艺流程,并进行了技术性能评价计算。计算过程采用化工模拟软件Aspen Plus,基于不同反应温度、水碳比、钙碳比等工艺操作参数,对各个操作单元进行物料平衡和能量平衡计算,并考察制氢性能指标产氢率和COG能量转化效率受制氢工艺操作参数影响的敏感度分析,得到最优操作参数范围。分析结果表明:ReSER-COG制氢工艺在反应温度600℃,水碳物质的量比4,钙碳物质的量比2.75,常压反应的条件下,1m^3COG可获得最大产氢气率为1.8m^3,且能量转化效率达到最高76.3%。与现有的COG制氢技术相比,ReSERCOG制氢技术在同样条件下,可以得到较高的产氢率和COG能量转化效率,具备较强的技术优势。Based on the experimental results,a reactive sorption enhanced coke oven gas(COG)steam reforming hydrogen production process(ReSER-COG)was established,and the technical performance evaluation was carried out according to the simulation results.The calculation of material balance and energy balance for each operation unit was completed based on different operation parameters such as temperature,molar ratio of water to carbon and calcium to carbon by using chemical process simulation software Aspen plus.Then the sensitivity analysis between the operation parameters and performance evaluation indices of hydrogen production including yield of hydrogen and efficiency of energy conversion was finished to get the optimum range of operation parameters.The results showed that under 600℃,steam tocarbonmolar ratio of 4,calcium to carbonmolar ratio of 2.75 and atmosphere pressure,ReSER-COG could obtain the maximumhydrogen yield of 1.8Nm3 per Nm^3 COG and the maximum energy conversion efficiency of 76.3%.Compared with the existing COG hydrogen production technologies,ReSER-COG process could obtain higher hydrogenyield and energy conversionefficiency in the same conditions,which makes it have strong technical advantages.
