Abstract: A hydrocarbon gas such as methane and LPG is desulfurized in the presence of oxygen and an oxidation catalyst to convert sulfur compounds in the gas to sulfur oxides. The sulfur oxides are then trapped downstream of the oxidation by an adsorbent. The amount of oxygen added to the hydrocarbon gas to promote oxidation is such that the sulfur compounds are selectively oxidized and the oxidation of the hydrocarbon gas is minimized to reduce hydrogen formation.

Abstract: Provided are improved carbon monoxide removal articles and processes for treating hydrogen gas streams to achieve very low threshold levels of carbon monoxide. The articles have a substrate with an inlet end, an outlet end, a length extending between the inlet end to the outlet end, wall elements and a plurality of cells defined by the wall elements. A first layer is deposited on the wall elements from the inlet end and extending at least partially toward the outlet end. The first layer has a preferential carbon monoxide oxidation catalyst. A second layer contains a methanation catalyst, and is deposited on at least part of the first layer from the outlet end. The second layer has a length that is about 10-70% of the substrate length.

Abstract: A process for the reduction of gaseous sulfur compounds in gaseous streams. The gaseous stream is contacted with a sorber, e.g., zinc oxide, which is capable of sorbing the sulfur compounds under sulfur sorbing conditions. The sorber is present in the form of one or more layers on the surface of a monolith carrier, e.g., cordierite. The layers of the sorber have a total thickness of at least 3 g/in3 of the carrier. The process is especially useful for the removal of gaseous sulfur compounds such as H2S from gaseous streams.

Abstract: Provided is a ruthenium-based catalyst having from about 1 to 10 wt. % of a ruthenium component and at least about 0.5 wt. % of zinc oxide. In one embodiment of the catalyst, zinc oxide itself serves as a support on which the ruthenium is dispersed. In another embodiment, the ruthenium component and the zinc oxide are dispersed on a refractory oxide support other than zinc oxide. In a process aspect, the ruthenium-based catalyst can serve as a preferential oxidation catalyst in processes for removing carbon monoxide from an input gas stream containing carbon monoxide, hydrogen and oxygen. The invention also provides articles wherein multi-stage preferential oxidation processes for removal of carbon monoxide from hydrogen streams can be conducted.
