An experimental study has been carried out on the synthesis of carbon nanomaterials using Fe catalyst in methane/air laminar, fuel-rich premixed flames under atmospheric pressure. By placing a pair of porous media in the upstream and downstream sides of the combustion space, excess enthalpy burning was applied to the methane/air mixture. We have investigated effects of reaction time on nanomaterials growth. As s result, carbon nanomaterials with a diameter of from 20 to 50nm have been synthesized in region near the downstream side of the porous medium.
