Abstract

Steam reforming (STR) and autothermal reforming (ATR) of n-heptane were studied on a 15 wt-% Ni/Al₂O₃ catalyst. The optimal temperature for H₂ production is 700 °C, where both the conversion of n-heptane and the selectivity to H₂ were high. At lower temperatures, thermal cracking of n-heptane occurred. The catalyst was active and selective, but coke accumulation was observed. Oxygen present in the ATR experiments reduced coke accumulation, which slowed the deactivation. According to the thermodynamics, the optimal O₂/C ratio was 0.34 mol/mol at 700 °C.
