At present, the infrastructure of hydrogen production, storage and transportation is poor. Fuel reforming for hydrogen production from liquid fossil fuels such as kerosene, petrol and diesel is of great significance for wide application of on-board fuel cell and distributed energy resources. In this work, the produced and heat released of kerosene, petrol and diesel reformed by different reforming methods (autothermal reforming, partial oxidation, steam reforming) were studied by means of thermodynamic analysis. Based on the thermodynamic analysis, the effect of reforming methods on the system's ideal thermal efficiency are analysed. The results show that the hydrogen concentration of syngas obtained from steam reforming is highest regardless of the fuel types. The hydrogen yielded by per unit volume of diesel is largest under same reforming method. Autothermal reforming has the largest ideal thermal efficiency among three reforming methods.
