摘要： A method of removing CO from a mixture of CO and saturated or unsaturated hydrocarbons is provided. In one embodiment, the method is to contact a feed stream with an oxygen transfer agent; and then oxidize at least a portion of the CO to CO2 to produce a stream enriched in CO2. The saturated and unsaturated hydrocarbons in the feed are not further oxidized during the oxidation. The oxygen transfer agent includes at least one of: i) water; ii) at least one reducible metal oxide; iii) at least one reducible chalcogen; or mixtures thereof. In another embodiment, the CO is converted to methane. The unsaturated hydrocarbons in the feed are not hydrogenated. In both of these alternatives, the CO2 or methane are then removed. Systems for removing the CO are also provided.

摘要： A process for production of ammonia includes: providing a reaction stream including carbon monoxide and hydrogen; passing the reaction stream and steam over a water gas shift catalyst in a catalytic shift reactor, forming a shifted gas mixture depleted in carbon monoxide and enriched in hydrogen; passing the shifted gas mixture with an oxygen-containing gas over a selective oxidation catalyst at ≧175° C., forming a selectively oxidized gas stream with a portion of the carbon monoxide converted to carbon dioxide; removing some of the carbon dioxide from the selectively oxidized gas stream in a carbon dioxide removal unit; passing the carbon dioxide depleted stream over a methanation catalyst in a methanator to form a methanated gas stream, optionally adjusting its hydrogen:nitrogen molar ratio to form an ammonia synthesis gas; and passing the ammonia synthesis gas over an ammonia synthesis catalyst in an ammonia converter to form ammonia.

摘要： The present invention relates to a method for preparing a catalyst comprising a ruthenium-containing catalyst layer highly dispersed with a uniform thickness on a surface of a substrate having a structure, which comprises first aging a mixed solution of a ruthenium precursor-containing solution and a precipitating agent to form a ruthenium-containing precipitate seeds, secondarily aging the first aged mixed solution to grow the seeds thereby forming ruthenium-containing precipitate particles, and then contacting the particles with a substrate to deposit the particles on the surface of the substrate. Since the catalyst has a structure in which the round shaped ruthenium-containing precipitate particles are piled to form the ruthenium-containing catalyst layer, it has a large specific surface area. Thus, the catalyst may exhibit excellent catalytic performance in various reactions for producing hydrogen using a ruthenium catalyst.
