Abstract

Natural gas is an interesting fuel for ships in coastal zones, where high sulfur marine fuels cannot be used. However, slip of unburnt methane from the engine poses another emission problem, as CH₄ is a green-house gas with an atmospheric potential 26-28 times that of CO₂ [1] and it should be mitigated from the exhaust gas. Catalytic oxidation of CH₄ to CO_{2 a}nd H₂O in the after treatment system can be a promising solution, but an efficient catalyst that remains sufficiently active under real exhaust gas conditions (350-550 °C, 5-10 vol.% H₂O and 1-2 ppm SO₂) is still being sought with the inhibition from SO₂ being a major issue. In this contribution, Rh and Pd were studied as promising active materials distributed on three different supports, i.e. zeolite (ZSM-5), silica, and alumina.
