    摘要： A method and apparatus for producing a substitute natural gas stream to be added to a natural gas stream in which at least part of a refinery gas stream is reacted in a catalytic reactor to hydrogenate olefins into saturated hydrocarbons. The extent to which hydrogen and olefins are reacted in the catalytic reactor is controlled to reduce the concentration of olefins in the resulting substitute natural gas stream and to increase the interchangeability of the substitute natural gas stream with the natural gas. This control can be effectuated by by-passing part of the refinery off gas to an intermediate product stream produced by the catalytic reactor and thereby forming the substitute natural gas stream from the by-passed refinery gas stream and the intermediate product stream.

    摘要： A steam methane reforming method in which a feed stream is treated in a reactor containing a catalyst that is capable of promoting both hydrogenation and partial oxidation reactions. The reactor is either operated in a catalytic hydrogenation mode to convert olefins into saturated hydrocarbons and/or to chemically reduce sulfur species to hydrogen sulfide or a catalytic oxidative mode utilizing oxygen and steam to prereform the feed and thus, increase the hydrogen content of a synthesis gas produced by a steam methane reformer. The method is applicable to the treatment of feed streams containing at least 15% by volume of hydrocarbons with two or more carbon atoms and/or 3% by volume of olefins, such as a refinery off-gas. In such case, the catalytic oxidative mode is conducted with a steam to carbon ratio of less than 0.5, an oxygen to carbon ratio of less than 0.25 and a reaction temperature of between about 500° C. and about 860° C. to limit the feed to the steam methane reformer to volumetric dry concentrations of less than about 0.5% for the olefins and less than about 10% for alkanes with two or more carbon atoms.
