The first widespread use of hydrogen is likely to be in transportation. In principle, hydrogen can be used as a fuel for internal combustion engines and fuel cells. All conventional options of hydrogen production from hydrocarbon fuels, e.g. steam reforming (SR), partial oxidation (PO) and autothermal reforming, involve production of synthesis gas with a large concentration of carbon oxides. Removal of CO/CO_2 from synthesis gas requires several expensive technological steps such as water gas shift reaction (WGSR), preferential oxidation, gas spearation, etc. One alternative to conventional processes is a CO/CO_2-free production of hydrogen and carbon by cataltyic prrolysis (CP) of hydrocarbons. CP is a technologically simple one step process without WGSR and gas separation stages. The e xperimental results on catalytic pyrolysis of different hydrocarbon fuels over metal and carbon catalysts are presented. It was demonstrated that the pyrolysis gas with hydrogen concentration in the range of 70-90 v.
