摘要： 燃料生命周期可划分为燃料生产阶段(Well-to-tank，WTT)和车辆使用阶段(Tank-to-wheel，TTW)。为分析天然气制氢在蒸气重整、压缩、液化、运输阶段的能量消耗和排放情况，根据氢的不同状态(气态或液态)及运输方式(管道、公路、铁路运输)，将天然气(Nature gas，NG)蒸气重整制氢在WTT阶段划分为12种燃料路线。采用能量守恒和转化原理及工艺燃料使用装置的能量消耗和排放因子，研究天然气制氢的原料及工艺燃料消耗所产生的一次能源能量消耗和气体排放。分析表明，不考虑输氢管道铺设，天然气制氢在WTT阶段的一次能源能量消耗由低到高依次分别为1.318 78 MJ•MJ–1、1.326 93 MJ•MJ–1、1.557 95 MJ•MJ–1、1.557 44 MJ•MJ–1、1.746 18 MJ•MJ–1，对应燃料路线为6、1、3、5、12。温室气体排放由少到多依次为156.18 g•MJ–1、162.11 g•MJ–1、163.37 g•MJ–1、168.53 g•MJ–1、176.01 g•MJ–1，对应的燃料路线为6、12、3、5、2。随着氢能消耗量的增加，采用燃料路线6(NG管路运输-工厂NG蒸汽重整集中制H2-H2管路运输-气站压缩-销售)，可以减少能量消耗和排放的产生。

Abstract: Fuel life cycle can be divided into production phase (Well-to-tank, WTT) and vehicle operation (Tank-to-wheel, TTW) phase. In corroding to analysis of energy consumption and emissions for hydrogen production by steam reforming with natural gas during stage of steam reforming, compression, liquefaction and transportation, hydrogen production by steam reforming with natural gas is divided into 12 kinds of hydrogen production mode according to different states of hydrogen (gaseous or liquid) and methods of transportation (pipelines, roads, rail transport). Using energy conservation or conversion principle and the energy consumption and emission factors for device of process fuel, primary energy consumption and emissions are researched for consumption of raw materials and processes fuel while hydrogen produced with natural gas. Without considering laying of transportation pipeline of hydrogen, analyses shows that primary energy consumption of hydrogen production with natural gas are 1.318 78 MJ•MJ–1、1.326 93 MJ•MJ–1、1.557 95 MJ•MJ–1、1.557 44 MJ•MJ–1、1.746 18 MJ•MJ–1from low to high in turn, corresponds to hydrogen production mode of 6、1、3、5、12. Greenhouse gas emissions from less to more than order are 156.18 g•MJ–1、162.11 g•MJ–1、163.37 g•MJ–1、168.53 g•MJ–1、176.01 g•MJ-1, corresponds to hydrogen production mode of 6、12、3、5、2. With the increase of hydrogen consumption, using hydrogen production mode of 6 (NG pipeline transport - H2 production by steam reforming with natural gas centralized in factory-H2 pipeline transportation - gas station compression - sales) can reduce energy consumption and emissions.

Key words: Emissions, Energy consumption, Hydrogen produced with natural gas, Steam reforming
