摘　　要：兰炭技术可以实现煤炭资源高效清洁利用,但兰炭生产过程中会副产兰炭尾气,若将其直接排放到大气中,不仅会造成能源浪费,还会污染环境。基于兰炭尾气组成φ(CH_(4)):φ(CO):φ(CO_(2)):φ(H_(2)):φ(N_(2))=8.7%:13.9%:12.7%:28.5%:36.2%,以利用H_(2)和减少温室气体排放为目的,探究了兰炭尾气制氢与捕碳的可能性。利用静态容积法测得了兰炭尾气各组成在活性炭、5A分子筛以及硅胶上的吸附等温线,为仿真模拟提供了相关参数。在此基础上,设计了三阶变压吸附制氢与捕碳工艺,旨在探索兰炭尾气清洁化利用方案。Blue coke technology can realize efficient and clean utilization of coal resource,but blue coke gas will be produced in the production process of blue coke.If the blue coke gas is directly discharged into the atmosphere,it will not only cause energy waste,but also pollute the environment.Based on the composition of blue coke gas:φ(CH_(4)):φ(CO):φ(CO_(2)):φ(H_(2)):φ(N_(2))=8.7%:13.9%:12.7%:28.5%:36.2%,the possibility of hydrogen production and carbon capture from blue coke gas was explored for the purpose of using H_(2) and reducing greenhouse gas emissions.The adsorption isotherms of each component of blue coke gas on activated carbon,5A molecular sieve and silica gel were measured by static volumetric method,which provid relevant parameters for simulation.On this basis,the third-stage pressure swing adsorption hydrogen production and carbon capture process was designed to explore the scheme of clean utilization of blue coke gas.
