    Abstract: Provided is a method of generating a hydrogen-rich reformate from a hydrocarbon feed stream comprising olefins and alkanes (e.g., LPG). An inlet gas stream containing the hydrocarbon feed stream and an oxygen containing gas stream, is preheated to a temperature of from 180 to 300null C. The preheated inlet gas stream is then contacted with a sulfur tolerant partial oxidation catalyst to form a pre-reformed gas stream, which is preferably maintained below about 400null C. The pre-reformed gas stream is then subjected to a reforming process to form the hydrogen-rich reformate.

    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.

    Abstract: A process for catalytically generating a hydrogen-rich gas from a hydrocarbon feed. A stream comprising the hydrocarbon feed, water and air is preheated to a temperature sufficiently high to initiate catalytic partial oxidation of the hydrocarbon feed. The preheated stream is then introduced into an autothermal reactor containing a layered catalyst member at a temperature sufficient to initiate and sustain both catalytic partial oxidation and catalytic steam reforming. At least part of the hydrocarbon feed is catalytically partially oxidized to produce a hydrogen-rich gas comprising hydrogen and carbon oxides and hydrocarbons remaining in the feed are steam reformed to produce further quantities of the hydrogen-rich gas. The layered catalyst member comprises a monolith substrate containing at least one layer of a steam reforming catalyst in contact with at least one layer of a catalytic partial oxidation catalyst. The steam reforming catalyst comprises one or more platinum group metal components and the catalytic partial oxidation catalyst comprises palladium components.
