Embodiment 1

[0058] After the presulfurization, hydrorefining was performed using an oil to be treated whose sulfur content in the oil to be treated was adjusted to 51 ppm by mass by adding dimethyl disulfide to palm oil. The treated oil had a density of 0.916 g / ml at 15°C and an oxygen content of 11.4% by mass. In addition, regarding the conditions of hydrofining, the reaction temperature of the first and second reaction tubes is 280°C, the pressure is 10MPa, and the liquid hourly space velocity is 0.6h -1 . It should be noted that the volume ratio of hydrogen introduced between the first reaction tube and the second reaction tube (quenching hydrogen ratio) was 20% by volume of the total hydrogen introduced, and the hydrogen / oil ratio obtained from the total amount of hydrogen introduced was 500 NL / L. The obtained results are shown in Table 2.

Abstract

The present invention discloses a hydrorefining process which is characterized in that an oil to be processed which contains an oxygen-containing hydrocarbon compound and a sulfur-containing hydrocarbon compound is brought into contact, in the presence of hydrogen, with a catalyst which contains a porous inorganic oxide containing two or more elements selected from aluminum, silicon, zirconium, boron, titanium and magnesium, and one or more metals selected from group 6A and group 8 elements of the periodic table and loaded on the porous inorganic oxide, at a hydrogen pressure of 2-13 MPa, at a liquid hourly space velocity of 0.1-3.0 h<-1>, at a hydrogen / oil ratio of 150-1500 NL / L, and at a reaction temperature of 180-380 DEG C.

Description

technical field [0001] The present invention relates to a hydrorefining method, and more specifically, to a method for hydrorefining an oil to be treated containing an oil and fat component derived from animal and vegetable oils. Background technique [0002] As a countermeasure against global warming, the effective use of biomass energy has attracted attention. Among biomass energy, biomass energy derived from plants can effectively use hydrocarbons converted from carbon dioxide through photosynthesis during the growth of plants, so it has the advantage of not increasing carbon dioxide in the atmosphere from the viewpoint of life cycle. The so-called carbon-neutral nature. [0003] Regarding utilization of such biomass energy, various studies are being conducted in the field of transportation fuels. For example, if fuel derived from vegetable oil can be used as diesel fuel, it can be expected to play an effective role in reducing carbon dioxide emissions due to the synerg...
