Steam reforming is a well-established industrial process for the production of hydrogen
from hydrocarbon fuels, in most cases from natural gas. High steam to carbon ratios are
applied to gain maximum methane conversion. Since steam reforming of natural gas is a
highly endothermic reaction it may also be applied as a chemical storage of renewable
energy. For this power-to-hydrogen application milder conditions and shorter operating
times are characteristic. However process efficiency declines with increasing S/C ratio for
storage applications. Though, when lowering S/C ratios one of the major challenges lies in
coke formation due to unwanted reactions. On this reason, experiments with different
hydrocarbon feedstock, including methane and a synthetic natural gas mixture were
conducted in a laboratory test rig to investigate the influence of very low S/C ratios in the
range of 0.1e0.4 and reaction temperatures between 450 and 500 °C at atmospheric pressure.
Measurements showed drastic decrease of catalyst life times when small amounts of
ethane and propane were added to the hydrocarbon feedstock. Long-term tests showed
that catalyst deactivation led to flattening of the temperature profile, changes in dry
product gas composition and rising pressure drop over fixed bed. Increase of reaction
temperature, lowering of S/C and use of higher hydrocarbons in the feed led to intense
carbon lay down.
