Problems solved by technology

[0004] However, in the process of producing fatty acid methyl esters, as described in the following Patent Document 1, the following problems have been pointed out: it is necessary to process by-produced glycerin, or it takes cost and energy to wash the produced oil, etc.
That is, fats and oils derived from animal and vegetable oils usually have oxygen atoms in their molecules, so the oxygen component may adversely affect the engine material, and it is difficult to remove the oxygen component to a very low concentration, etc.
In addition, when oils and fats derived from animal and vegetable oils are used in combination with petroleum-based hydrocarbon fractions, the contents of both the oxygen component in the fats and oils and the sulfur content in the petroleum-based hydrocarbon fraction cannot be sufficiently reduced by conventional techniques.

Embodiment 1

[0082] A reaction tube (inner diameter 20 mm) filled with 50 ml of catalyst A was installed on a fixed-bed flow-through reactor. Next, use straight-run light oil (3% by mass of sulfur) added with dimethyl disulfide at an average temperature of 300°C in the catalyst layer, a hydrogen partial pressure of 6 MPa, and a liquid space velocity of 1 h -1 , Under the condition of 200NL / L hydrogen / oil ratio, presulfide catalyst A for 4 hours.

[0083] Pass palm oil (density at 15°C: 0.916g / ml, oxygen content: 11.4 mass%, chlorine content: 4.1 mass ppm, iodine value: 51.1) into the above reaction device. The compound with triglyceride structure contains oxygen The proportion of organic compounds: 99.6 mol%) as the feedstock oil, at a reaction temperature of 310℃, LHSV1.0h -1 , Hydrotreating under the conditions of hydrogen pressure 5MPa and hydrogen-oil ratio 600NL / L.

[0084] Next, water is separated and removed from the reaction fluid after the hydrogenation treatment to obtain the target p...

Embodiment 2

[0086] Except that catalyst B (50 ml) was used, and the reaction temperature was 330°C, the hydrogenation treatment and water separation were performed in the same manner as in Example 1. Table 2 shows the amount of water that is by-produced by the hydrogenation treatment, the concentration of the chlorine component in the water, and the chlorine component content, oxygen component content, and iodine value of the produced oil.

Embodiment 3

[0088] In addition to soybean oil (density at 15°C: 0.923g / ml, oxygen content: 11.5% by mass, chlorine content: 1.8 mass ppm, iodine value: 136, compounds with triglyceride structure are contained in oxygen-containing organic compounds Percentage: 99.5 mol%) Except for the feedstock oil, the hydrogenation treatment and water separation were performed in the same manner as in Example 1. Table 2 shows the amount of water that is by-produced by the hydrogenation treatment, the concentration of the chlorine component in the water, and the chlorine component content, oxygen component content, and iodine value of the produced oil.

Abstract

The following process for producing a hydrocarbon oil is provided. First, in the presence of hydrogen, a raw oil containing an oxygenous organic compound and a water-insoluble chlorinous compound is brought into contact with a hydrogenation catalyst composed of a support containing a porous inorganic oxide and, supported thereon, at least one metal selected from among those of Group VIA and Group VIII of the periodic table so as to form a hydrocarbon oil and water through hydrogenation deoxygenation of the oxygenous organic compound and convert the water-insoluble chlorinous compound to a water-soluble chlorinous compound, thereby obtaining a reaction product containing the hydrocarbon oil, water and the water-soluble chlorinous compound. Subsequently, the water containing the water-soluble chlorinous compound is separated from the reaction product, thereby obtaining a produced oil containing the hydrocarbon oil.

Description

Technical field [0001] The present invention relates to a method for producing hydrocarbon oil. Background technique [0002] As a countermeasure against global warming, the effective use of biomass energy is attracting attention. Among biomass energy, plant-derived biomass energy can effectively use the hydrocarbons converted from carbon dioxide through photosynthesis during the growth of plants, so it has nothing to do with the increase of carbon dioxide in the atmosphere from the viewpoint of life cycle. The nature of the carbon neutral (Carbon Neutral). [0003] Various researches on the utilization of such biomass energy are also being conducted in the field of transportation fuels. For example, if fuel derived from animal and vegetable oils is used as a diesel fuel, it is expected to play an effective role in reducing carbon dioxide emissions by synergistically with the high energy efficiency of the diesel engine. As diesel fuel using animal and vegetable oils, Fatty Acid ...
