- Hydrogen can be produced by reforming a part of such a light hydrocarbon fraction produced by a steam reformer.
- the hydrogen produced in this way has a carbon neutral characteristic because the raw material used for steam reforming is a biomass-derived hydrocarbon, which can reduce the burden on the environment. .
- Water, carbon monoxide, carbon dioxide, hydrogen sulfide, etc. may be generated with the reaction of oxygen and sulfur contained in the oil to be treated.
- Gas-liquid separation equipment and other by-product gas removal devices may be installed in the recovery process.
- Hydrogen gas is generally introduced from the inlet of the first reactor along with the oil to be treated before or after passing through the heating furnace. Separately, the temperature in the reactor is controlled. In addition, hydrogen gas may be introduced from between the catalyst beds or between a plurality of reactors in order to maintain the hydrogen pressure throughout the reactor.
- the hydrogen introduced in this way is generally called Taenti hydrogen.
- the ratio of Taenthi hydrogen to the hydrogen gas introduced along with the oil to be treated is preferably 10 to 60% by volume, more preferably 15 to 50% by volume. If the proportion of Taenti hydrogen is less than 10 volumes, the reaction at the subsequent reaction site tends not to proceed sufficiently. If the proportion of Taenti hydrogen exceeds 60% by volume, the reaction near the reactor inlet proceeds sufficiently. There is a tendency not to.
- Sulfur content that preferably contains a fraction having a boiling point of 260 to 300 ° C, a sulfur content of 15 mass ppm or less and an oxygen content of 0.5 mass% or less. More preferably, the content of is 12 mass ppm or less and the oxygen content is 0.3 mass% or less. If the sulfur content and oxygen content exceed the above upper limits, it may affect the filters and catalysts used in diesel engine exhaust gas treatment equipment, as well as the engine and other materials.
- the hydrorefined oil produced by the present invention can be suitably used particularly as a diesel light oil or heavy oil base material.
- the hydrorefined oil may be used alone as a diesel light oil or heavy oil base material, but can be used as a diesel light oil or a heavy base material mixed with components such as other base materials.
- a gas oil fraction and / or kerosene fraction obtained in a general petroleum refining process and a residual fraction obtained by the hydrorefining method of the present invention can be mixed.
- synthetic light oil or synthetic kerosene obtained through a Fischer-Tropsch reaction or the like using so-called synthesis gas composed of hydrogen and carbon monoxide as a raw material can be mixed.
- These synthetic light oils and kerosene are characterized by containing almost no aromatics, mainly consisting of saturated hydrocarbons, and high cetane numbers.
- a known method can be used as a method for producing the synthetic gas, and is not particularly limited.
- the residual fraction obtained by the hydrorefining method of the present invention has a sulfur content of 0.1% by mass or less, an oxygen content of 1% by mass or less, and a low sulfur heavy content. Can be used as a base material.
- the residual fraction is suitable as a feedstock for catalytic cracking. In this way, by using the residual fraction having a low sulfur level for the catalytic cracking apparatus, it is possible to produce a gasoline base material and other fuel oil base materials with a low sulfur content. Further, the residual fraction can be used as a feedstock for hydrocracking. By using such a residual fraction in a hydrocracking apparatus, it is possible to improve the cracking activity and improve the quality of each fraction of the product oil.
- the cake-like slurry was transferred to a vessel equipped with a reflux condenser, and 150 ml of distilled water and 10 g of a 27% aqueous ammonia solution were added and stirred at 75 ° C for 20 hours.
- the slurry was put in a kneading apparatus, heated to 80 ° C. or higher and kneaded while removing moisture to obtain a clay-like kneaded product.
- the obtained kneaded product was extruded into a shape of a cylinder having a diameter of 1.5 mm by an extrusion molding machine, dried at 110 ° C. for 1 hour, and then fired at 550 ° C. to obtain a molded carrier.
- a 3000 g aqueous solution of sodium aluminate having a concentration of 5% by mass was placed in a container kept at 65 ° C.
- 3000 g of an aluminum sulfate aqueous solution having a concentration of 2.5% by mass was prepared, and the aforementioned sodium aluminate aqueous solution was added dropwise thereto.
- the end point was when the pH of the mixed solution reached 7.0, and the obtained slurry product was filtered through a filter to obtain a cake-like slurry.
- the cake-like slurry was transferred to a container equipped with a reflux condenser, 150 ml of distilled water and 10 g of a 27% ammonia aqueous solution were added, and the mixture was heated and stirred at 75 ° C for 10 hours.
- the slurry was put into a kneading apparatus, heated to 80 ° C. or higher and kneaded while removing moisture to obtain a clay-like kneaded product.
- the resulting kneaded product was extruded into a shape of a cylinder with a diameter of 1.5 mm using an extrusion molding machine. And dried at 550 ° C for 1 hour to obtain a shaped carrier.
- a first reaction tube (inner diameter 20 mm) filled with catalyst A (50 ml) and a second reaction tube (inner diameter 20 mm) also filled with catalyst A (50 ml) were attached in series to a fixed bed flow reactor. Then, using straight-run gas oil (3% by mass of sulfur) with dimethyl disulfide added, catalyst layer average temperature 300 ° C, hydrogen partial pressure 6MPa, liquid space velocity lh—hydrogen / oil ratio 200NLZL The catalyst was presulfided for 4 hours.
- the volume ratio of hydrogen gas introduced between the first reaction pipe and the second reaction pipe (Taenti hydrogen ratio) is 20% by volume of the total hydrogen introduced, and the hydrogen / oil ratio determined from the total hydrogen introduced is 500 NL / L. Table 2 shows the results obtained. [0059] (Comparative Example 1)
