摘要
构建了基于非混合燃烧的焦炉煤气自热重整制氢系统,将回收焦炉煤气用于制氢.对该系统进行模拟和分析,结果表明,基于非混合燃烧的焦炉煤气自热重整制氢系统可以用于制氢,在产物干气中氢气浓度可达92.4%;通过调整进料量并合理分配系统热量,可使整个系统达到自热平衡,无需外界供给额外热量,系统制氢的热效率可达80.7%;该系统采用的非混合燃烧技术避免了焦炉煤气与空气的直接接触,尾气中包含的CO2不会被空气中的N2所稀释,可以有效地对CO2进行捕集.
Based on the benefits of unmixed combustion （UMC）, a system using coke oven gas （COG） for hydrogen production is established. Using the simulation software to analyze and optimize the running conditions, the results show that this system is fit for highly concentrated hydrogen production from coke oven gas, and a 92. 4~ Hz concentration in the dehydrated gas is achieved. The system can provide heat for itself without requiring extra heat, and reach a high thermal efficiency of 80. 7%. The carbon dioxide vented by the system is unlikely to be diluted by the nitrogen in air, and the carbon dioxide can be captured conveniently and effectively.
