A study of carbon deposition on catalysts during the catalytic partial oxidation of methane to syngas in a fluidized bed

The deposition of carbon on catalysts during the partial oxidation of metha ne to syngas has been investigated in a fluidized bed. It was found that th e relative rate of carbon deposition follows the order NiP > >d > Pt, Rh. A lthough the rate of carbon deposition in the fluidized bed was much lower t han that in the fixed bed, carbon deposition could still be detected in the fluidized bed if a CH4/O-2 ratio in greater than 2.3 was used.
