Investigation of Cobalt Promoted Fe/Γ-Al2o3 Catalyst in Catalytic Combustion of Methane Process

Catalytic combustion of methane was performed in the presence of two catalysts of 10fe2o3/γ-al2o3 and 10fe2o3-4co3o4/γ-al2o3# reactor tests were carried out at the temperature range of 300 to 550 °c in a fixed-bed quartz reactor# 10fe2o3/ γ-al2o3 was prepared via wet impregnation method and its catalytic activity was evaluated in methane combustion reaction in the presence of methane, oxygen and argon gases# in order to study the effect of cobalt promoter on the catalytic activity of iron catalyst supported on gamma-alumina, 10fe2o3-4co3o4/γ-al2o3 was synthesized by simultaneous impregnation# results showed better performance for the cobalt promoted catalyst due to improvement of active sites dispersion# increase of methane conversion was observed using cobalt promoter, so that methane conversion increased about 4% and 40% at 300 and 500 °c, respectively# 90% methane conversion was obtained using 10fe2o3-4co3o4/γ-al2o3 catalyst at 550 °c#
