ABSTRAKT

The preparation of a suitable fuel is the main problem for the introduction of fuel cell systems. Hydrogen is not a carrier of primary energy, and must therefore be generated from other energy sources. At present, the majority of available developed and commercial techniques are those that produce hydrogen from natural gas by steam reforming. The process cannot be employed for hydrocarbons with a boiling point above 220°C, as there is an increased tendency for soot to form. Therefore, higher hydrocarbons are transformed into gaseous fuel by exothermic partial oxidation with the supply of oxygen. However, similar processes for liquid fuels have not yet been developed. One problem is the tendency for soot to form, which is generally caused by unfavorable mixtures of liquid fuels and air. This article will present the influence of the sulphur content in the fuel and the fuel type on the partial oxidation process (catalytic or non-catalytic), as well as the influence of the system pressure and the steam-to-carbon ratio on the resulting concentrations of hydrogen and carbon monoxide.
