摘要： A method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a hydrogen plant having a steam methane reformer in which an untreated hydrocarbon containing stream is introduced into two reaction stages connected in series to hydrogenate olefins and to convert organic sulfur species to hydrogen sulfide. The second of the two stages can also be operated in a pre-reforming mode to generate additional hydrogen through introduction of the oxygen and steam into such stage. A sulfur tolerant catalyst is used in both stages to promote hydrogenation and oxidation reactions. Sulfur is removed between stages by adsorption of the hydrogen sulfide to prevent deactivation of the catalyst in the second of the stages that would otherwise occur during operation of the second reaction stage in a pre-reforming mode of operation.

摘要： The present invention provides a method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a steam methane reformer of a hydrogen plant. In accordance with such method, amounts of olefins and organic sulfur species within an untreated feed are decreased in a reactor that is operated in either a hydrogenation mode to hydrogenate the olefins into saturated hydrocarbons or a pre-reforming mode in which hydrocarbon containing two or more carbon atoms including the olefins are reacted with oxygen and steam to form saturated hydrocarbons, methane, additional hydrogen and carbon monoxide. The reactor is configured and operates at a sufficiently high space velocity that olefin and organic species slip occurs that is further treated in a hydrotreater. The reactor contains a catalyst capable of promoting both hydrogenation and oxidation reactions and the hydrotreater contains a catalyst that is capable of only promoting hydrogenation reactions.

摘要： A process for producing a purified hydrogen product without a pre-reformer or pre-reforming catalyst in a fired, tubular reformer where the feed stream having a carbon (i.e., C2+) molar composition greater than or equal to five percent and is mixed with a steam stream to yield a reformer feed stream with a steam-to-carbon ratio less than or equal to three. The reformer tubes contain a nickel-based catalyst without alkali promotion.
