- Non-Patent Document 1 “Zeolite”, Vol. 6, 1986, p. 334-348
- An object of the present invention is to improve the process economics by providing a novel hydrocracking catalyst for paraffinic hydrocarbons that simultaneously satisfies high cracking activity, high middle distillate yield, and low pour point of produced gas oil. To make it happen.
- the present invention relates to a hydrocracking catalyst for paraffinic hydrocarbons, comprising a crystalline aluminosilicate and an alumina polya, and containing a noble metal of Group VIII of the periodic table.
- the present invention also relates to the catalyst as described above, wherein the crystalline aluminosilicate has an average particle size of 0.5 m or less.
- the present invention relates to a method for producing a liquid hydrocarbon, comprising hydrocracking a paraffinic hydrocarbon using the above-mentioned catalyst.
- a method for producing a liquid hydrocarbon comprising hydrocracking a paraffinic hydrocarbon using the above-mentioned catalyst.
- the alumino silicide refers to a metal oxide composed of three elements of aluminum, silicon and oxygen. Further, other metal elements can be coexistent within a range not to impair the effects of the present invention. However, the amount of other metal elements is 5% by mass or less, preferably 3% by mass of the total amount of alumina and silica as oxides thereof. It is desirable that the content be not more than mass%.
- the metal element that can coexist include titanium, lanthanum, manganese, gallium, and zinc, and preferably titanium and lanthanum.
- the crystallinity of aluminosilicate is based on the four-coordinate aluminum- ⁇ It can be estimated in terms of the percentage of atom atoms, which can be measured by 27 A1 solid state NMR.
- the crystalline aluminosilicate refers to an aluminosilicate having a tetracoordinate aluminum ratio of 50% or more. Any 50% or more can be used as the crystalline aluminosilicate of the present invention, but preferably 70% or more, more preferably 80% or more.
- so-called zeolite can be used as the crystalline aluminosilicate.
- Preferred crystalline aluminosilicates include Y-type or US Y-type zeolite, beta-type zeolite, mordenite, ZSM-5, etc., and most preferred crystalline aluminosilicate includes US Y-type zeolite. Can be. If necessary, two or more crystalline aluminosilicates can be used in combination.

- the above catalyst containing crystalline aluminosilicate and alumina polya and containing a noble metal of Group VIII of the Periodic Table can be used for the hydrocracking of paraffinic hydrocarbons. By using this, it is possible to produce a liquid hydrocarbon that simultaneously satisfies the three requirements of high cracking activity, high middle distillate yield, and low pour point of the produced gas oil.
- a 1/16 inch (approximately 1.6 mm) cylindrical support consisting of 30 g of 113 ⁇ zeolite with an average particle size of 0.4 / ⁇ 111 and 970 g of alumina polya is used. After soaking containing an aqueous solution of mass 0/0 and becomes the amount of dichloro tetraamine platinum (II), which more firing for 1 hour at 3 hours drying and 500 ° C at 1 20, to prepare a catalyst.
- II dichloro tetraamine platinum
- the catalyst (200 ml) prepared as described above was charged into a fixed bed flow-through reactor and used for hydrocracking paraffinic hydrocarbons.
- FT wax with a paraffin content of 95% and a carbon number distribution from 20 to 80 was used as the paraffinic hydrocarbon.
- the hydrogen pressure was 3 MPa, and the liquid hourly space velocity was 2.0 / h.
- the reaction temperature at which 80% by mass of the decomposition product is obtained based on the starting material and the middle distillate based on the starting material (boiling point: 145 to 360 ° C)
- the pour point of the produced light oil (boiling point: 260-360 ° C) was determined. Table 1 shows the results.
- a catalyst preparation and hydrocracking reaction were carried out in the same manner as in Example 1 except that USY zeolite having an average particle diameter of 0.8 m was used, and the reaction temperature and raw materials when 80% by mass of a decomposition product were obtained were obtained.
- the yield of the middle distillate (boiling point: 145 to 360 ° C) and the pour point of the produced light oil (boiling point: 260 to 360 ° C) were determined. The results are shown in Table 1.
- Example 2 A catalyst preparation and hydrocracking reaction were carried out in the same manner as in Example 1 except that alumina was used instead of alumina polya.
- the yield and the pour point of the produced gas oil (boiling point was 260 to 360 ° C) were determined. The results are shown in Table 1. Comparative Example 2>
- Catalyst preparation and hydrocracking reaction were carried out in the same manner as in Example 1 except that 5% by mass of nickel and 15% by mass of tungsten were supported on the carrier instead of platinum, and 80% by mass of decomposition products were obtained.
- the decomposition temperature at which it was obtained, the middle distillate relative to the raw material (boiling point: 145-360 ° C), the yield, and the pour point of the produced gas oil (boiling point: 260-360 ° C) were determined.
- the results are shown in Table 1.
- Table 1 the combination of crystalline aluminosilicate and alumina polya provides high decomposition activity, high middle distillate yield and low pour point at the same time. It turns out to be satisfied.
- noble metals of Group VIII of the periodic table are effective as active metals.
