Catalytic combustion of lean methane–air mixtures

Abstract

Catalytic combustion of lean methane–air mixtures was studied on supported iron oxide and platinum monolith catalysts. Flameless catalytic combustion was investigated in the temperature range 600–900°C, GHSV up to 10 000 h −1, and methane concentration in initial gas mixture 1–9 vol%. It was shown that under certain process conditions complete combustion of methane at ∼4.5 vol% inlet methane concentration occurs.
