Abstract:
The present invention relates to a method of manufacturing naphtha, wherein, in hydrogenation of a naphtha fraction which is fractionated from synthetic oil (FT synthetic oil) obtained by Fisher-Tropsch synthesis, the hydrogenised component is recycled and the recycled amount thereof is adjusted to reduce a olefin content in a hydro-refining apparatus whereby heat generation is suppressed and unstable operation of the hydro-refining apparatus can be stabilized. Furthermore, the present invention relates to a method of manufacturing naphtha, wherein a cut point for fractionating a naphtha fraction from FT synthetic oil is adjusted to reduce the amount of olefin in a hydro-refining apparatus whereby unstable operation of the hydro-refining apparatus can be stabilized.
