摘　　要：氢能规模应用需要储运数以亿立方米计的氢源,液氢储存在各种储氢方式中规模实用化的优势明显。提出采用新的低温分离法将焦炉气中的氢分离并同时液化,及分区液化和分段加压模型。通过分离模型的能耗计算,表明分段加压能大大减少流程能耗,计算结果对新流程的组织有指导作用。Hundred million cubic meters of hydrogen should be stored and transported for the largescale hydrogen energy system. Liquid hydrogen storage has evident advantages among various storage methods in practical hydrogen system. Ten billion cubic meters of hydrogen are dissipated to the environment along with the emission of coke-oven gas every year in china. A new separation and liquefaction of hydrogen at the same time by means of a new cryogenic separation method was presented. The divisional liquefaction and segmented pressurizing model are proposal. The calculation indicated that segmented pressurizing can greatly decrease the energy consume. The calculation results provide a useful principle for the design of the large-scale hydrogen separation processes.
