Progress in hydrogen production from the steam reforming of typical hydrocarbons

烃水蒸气重整是目前获取氢能源的重要方法之一,而甲烷、汽油和柴油作为典型烃类原料可满足于不同规模氢能源的需求。本文重点从催化剂、反应工艺和反应机理及动力学三个方面对甲烷、汽油和柴油蒸汽重整制氢进行介绍和评述。指出甲烷重整制氢镍基催化剂的改性和反应器设计以及反应条件的优化是其必然的发展趋势,汽油和柴油重整制氢催化剂未来设计必须具备高抗硫性和抗积炭性。此外,需加强甲烷、汽油和柴油蒸气重整制氢的机理和动力学研究。

Steam reforming of hydrocarbons is one of the most important methods for hydrogen production at present.Methane,gasoline and diesel can be applied to different scale hydrogen production as typical hydrocarbons.The catalyst,process as well as mechanism and kinetics in hydrogen production from steam reforming of methane,gasoline and diesel,are reviewed.It reveals that nickel-based catalyst modification,reactor design and optimization of reaction conditions should be considered in the future development of steam reforming of methane.Catalysts for steam reforming of gasoline and diesel must have excellent tolerance to sulfur and resistance to carbon deposition.In addition,studies on mechanism and kinetics should be intensified.
