Problems solved by technology

[0003] However, synthetic oil obtained by the FT synthesis method (hereinafter sometimes referred to as "FT synthetic oil") has a high content of normal paraffins and contains oxygen-containing compounds such as alcohols, so it is difficult to directly use the synthetic oil as a fuel
More specifically, if this synthetic oil is used as motor gasoline, its octane number is insufficient, and if it is used as diesel fuel, its low-temperature fluidity is insufficient.
In addition, oxygen-containing compounds such as alcohols have adverse effects on the oxidation stability of fuels

Abstract

A process for the production of hydrocarbon oil, characterized by comprising subjecting a synthetic oil obtained by the Fischer-Tropsch process to fractional distillation to obtain a middle cut which has a content of distillates having boiling points of 150 to 360 DEG C of 90% by mass or above and a content of distillates having boiling points of 350 DEG C or above of 5% by mass or below and a wax component heavier than the middle cut, bringing the middle cut and the wax component separately into contact with a hydrogenation catalyst in the presence of hydrogen, mixing the hydrogenated middle cut with the hydrogenated wax component, and subjecting the mixture to fractional distillation to obtain a hydrocarbon oil which has a content of distillates having boiling points of 150 to 360 DEG C of 86% by mass or above and a content of distillates having boiling points of 350 DEG C or above of 5% by mass or above.

Description

technical field [0001] The present invention relates to a hydrocarbon oil and a method for producing the same, and more specifically, relates to a hydrocarbon oil which can be used as a diesel fuel base material and a method for producing the same. Background technique [0002] In recent years, from the viewpoint of reducing the environmental load, there has been a demand for clean liquid fuels that are low in sulfur components and aromatic hydrocarbons and are environmentally friendly. Therefore, in the petroleum industry, a Fischer-Tropsch synthesis method (hereinafter abbreviated as "FT synthesis method") using carbon monoxide and hydrogen as raw materials is being studied as a method for producing clean fuel. According to the FT synthesis method, alkane-rich and sulfur-free liquid fuel substrates can be produced, so there are great expectations for it. [0003] However, synthetic oil obtained by the FT synthesis method (hereinafter sometimes referred to as "FT synthetic...
