Interinfluence between Reactions on the Catalyst Surface and Reactions in the Gas Phase during the Catalytic Oxidation of Methane with Air

摘要: Abstract Direct catalytic oxidation of CH4 with air was studied using a wire-mesh reactor and quartz tube reactor. Two types nickel-containing catalysts (nickel Monel 400 alloy) in the form were used. The features minimisation thermally induced gas-phase reactions by rapidly quenching products leaving mesh catalyst surface. can be used as differential for study both exothermic endothermic reactions, on surface not controlled heat transfer. Increasing total gas flow rate passing through caused only increases overall reaction rates but also changes product selectivities. With reduction thickness film around wires, coupling CH3 radicals desorbed from becomes an important route C2H6 formation during air, even at 950°C. has proved to powerful tool understanding without complications phase. Comparison results those indicates that phase inhibited interinfluence between surface-catalysed must considered evaluating intrinsic
