Abstract
A catalyst for removing hydrocarbons from exhaust gas containing methane and an excess of oxygen, which comprises palladium or palladium/platinum supported on at least one carrier selected from zirconia, sulfated zirconia and tungsten-zirconia, and a method for treating exhaust gas using the catalyst.
Claims
exact text as granted — not AI-modified1 . A catalyst for removing methane from exhaust gas containing methane, sulfur dioxide, and an excess of oxygen, which comprises palladium supported on at least one carrier selected from zirconia, sulfated zirconia and tungsten-zirconia.
2 . The catalyst according to claim 1 wherein the weight proportion of supported palladium is 2% to 20% relative to the carrier.
3 . A catalyst for removing methane from exhaust gas containing methane, sulfur dioxide, and an excess of oxygen, which comprises palladium and platinum both supported on at least one carrier selected from zirconia, sulfated zirconia and tungsten-zirconia.
4 . The catalyst according to claim 3 wherein the weight proportion of supported palladium is 2% to 20% relative to the carrier and the weight proportion of supported platinum is 10% to 50% relative to the palladium.
