Since it has a low cetane number of about 15 to 25 and contains a large amount of polycyclic aromatic components (that is, naphthalene or its derivative as the main component), the hue is unstable, in addition. However, since it cannot be mixed and used in a large proportion with other straight-running materials, and it is difficult to select a suitable hydrorefining condition, the cetane number of FCC-LCO or coal liquefied oil is suitable as the fuel. It has not been put into practical use yet.

In particular, a catalyst and reaction conditions having a function of performing a partial nuclear hydrogenation reaction of naphthalene or a naphthalene derivative, that is, conversion into a tetralin and / or a tetralinalkyl derivative are preferable.

As a guide for selecting conditions, the amount of tetralin and / or tetralinalkyl derivative in the produced oil is as large as possible, that is, 1.
0% or more, preferably 1.3% or more, more preferably 2% or more. The tetralin or tetralin alkyl derivative is produced by partial nuclear hydrogenation of a naphthalene compound.
Therefore, there is no particular upper limit in the oil, and a larger amount is more effective, but about 15 wt% or less is sufficient.

Further, the production of indane is also effective in the effect of the present invention. On the other hand, it is desirable to suppress the production amount of decalin or a decalin derivative, that is, to select conditions of 5.0% or less, preferably 2.0% or less, particularly preferably 1.0% or less.
The production of decalin is not preferable because of the partial oxidation to be performed thereafter.
Further, as another index in the hydrotreatment, nd of produced oil is

The C N % is 30 to 45, preferably 30 to 40, and the C P % is 30 to 35.

にとどまる。FCC−LCOにおいても同様である。In the hydrotreatment of coal liquefied oil, the same conditions as FCC-LCO can be used. A large amount of naphthalene hydrocarbons is contained in coal liquefied oil. Therefore, it should be converted to tetralin hydrocarbons and the conversion to decalin should be suppressed. The cetane number improves as the hydrotreating conditions become more severe, but even with LHSV 0.2 hr -1 , it only rises to about 45. The same applies to FCC-LCO.

m 2, at a temperature 60 to 100 [° C., either stand 3-10 hours, further,
The copper or Ni-based catalyst may be present and stirred under more mild conditions. The conditions for partial oxidation are not particularly limited. As a result, the peroxide value in oil is 500
The above can be made 1000 or more, preferably 1500 or more. The higher the peroxide value, the higher the cetane number. In particular, by using a raw material containing a large amount of tetralin, it is possible to obtain a peroxide value of 1500 or more, and thus a fuel having a higher cetane number can be obtained. The hue of the oil may change to brown due to partial oxidation, but the hue can be improved by bringing the oil into contact with clay. Therefore, during the partial oxidation, adding a small amount of tetralin to the hydrorefined oil to increase the tetralin in the crude oil to 2 to 15 wt% can further increase the cetane number after the partial oxidation.

For cetane number 14 by hydrogenation and partial oxidation treatment,
It can be converted to fuel with a cetane number of 50 to 75. The present invention and its effects will be described below based on Examples.

Was filled with pure oxygen at 7.0 kg / cm 2 , placed in a constant temperature bath at 100 ° C., allowed to stand for 8 hours, then left to cool and taken out. By this operation, 100 cc of partially oxidized oil was obtained. Table 2 shows the measurement results of the peroxide number and cetane number of the oils obtained by partial oxidation from each hydrotreated oil. The cetane number was measured as follows.
市販の軽油（セタン価48.4）900ccと前記の部分酸化

Even if the oil is partially oxidized, there is almost no improvement in the cetane number. In the hydrotreatment, increasing tetralin, while suppressing the production of decalin, increases the effect of improving the cetane number by the subsequent partial oxidation.
