An experimental study has been carried out on the synthesis of carbon nanomaterials using rice hulls and Fe catalyst in methane/air laminar, fuel-rich premixed flames under atmospheric pressure. By placing a pair of porous media on the upstream and downstream sides of the combustion space, excess enthalpy burning was applied to the methane/air mixture. Rice hulls were uniformly scattered on a Ni porous medium with Fe catalyst that was placed in the combustion space. We have investigated the effects of Fe catalyst and the reaction temperature on nanomaterials growth. As a result, it has been found that carbon nanotubes are synthesized in non-luminous region.
