    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.
