Definitions
- the present invention relates to a method for hydrogenating orefin.
- US Pat. No. 3,127,452 discloses a method of hydrogenating ⁇ -methylstyrene and hydrogen by passing an olefin-containing liquid and a hydrogen-containing gas through an upflow through a packed bed of solid hydrogenation catalyst.
- a technique for supplying hydrogen to a catalyst layer and hydrogenating it is disclosed.
- conventional methods have not always been satisfactory in terms of producing cumene at low cost. Disclosure of the invention
- the present invention provides a method for hydrogenating an oil having an excellent effect that the reaction rate per unit catalyst is high.
- the present invention relates to a method for hydrogenating orefin in which a liquid containing orefin and a gas containing hydrogen are passed through an upflow through a packed bed of a solid hydrogenation catalyst, and the gas superficial velocity is 3.0 cmZs. It is related to the method of hydrogenating Olefin having an ec or more.
- the hydrogenation catalyst solid used in the hydrogenation of Orefin for example, Cu_ ⁇ as a component, C r 2 ⁇ 3, Zn_ ⁇ , Fe0 3, A 1 2 0 3, La 2 0 3, Sm 2 ⁇ 3, Ce_ ⁇ 2, Z R_ ⁇ 2, T I_ ⁇ 2, S i 0 2, Mn_ ⁇ 2, Co 2 0 3, N i O, BaO, CaO, metal oxide contains at least one kind of the MgO Ya , Pd, Rh, Pt; and precious metal catalysts containing Ru.
- the solid hydrogenation catalyst may be one using a carrier or one not using a carrier.
- the carrier is silica, Metal oxides such as lumina, titania, zirconia, magnesia, and silica-alumina and their composite oxides; bentonite, montmorillonite, diatomaceous earth, acid clay, activated carbon, ceramics and the like can be mentioned.
- the shape of the catalyst may be spherical or cylindrical, and the size of the catalyst is usually 0.5 to 10 mm. If the size is too small, the pressure loss increases, so that the economic efficiency is deteriorated and the size is too large. In addition, the reaction fluid is undesirably reduced in the catalytic activity and the reaction fluid drifts in the apparatus.
- the hydrogenation reaction of Orefin is performed using a reactor filled with the above-mentioned solid hydrogenation catalyst.
- the reaction temperature is usually from 20 to 500 ° C, preferably from 40 to 350 ° C, and the reaction pressure is usually from 0.1 to 2 OMPa, preferably from 0.1 to 10 MPa. .
- the amount of the catalyst to be used is usually 0.01 to 50 hr- 1 as the space velocity of the liquid containing olefin, and the raw material liquid containing fresh olefin is diluted with an appropriate solvent or water.
- the reaction solution after the addition reaction may be diluted with a partially recycled solution.
- the amount of hydrogen is usually 1.0 to 30 times the amount of olefin fed, and it can be diluted with an appropriate gas that does not react with the supplied olefin, or the excess hydrogen can be recycled. You may.
- Examples of the olefin include compounds containing a double or triple bond, such as styrenes.
- styrenes include styrene and ⁇ -methylstyrene.
- the liquid containing olefin and the gas containing hydrogen are passed through the packed bed of the solid hydrogenation catalyst in upflow.
- the reason for the upflow is that the liquid can be uniformly flowed into the packed bed without drifting, so that the generation of hot spots due to the reaction heat makes it difficult to control the reaction temperature, and the reaction runs away. This is because it can be suppressed.
- the gas superficial velocity is 3.0 cm / sec or more, and preferably 3.5 cm / sec or more. If the gas superficial velocity is lower than 3.0 cm Z sec, the hydrogenation reaction rate of Orefin will be high, and the rate at which hydrogen in the gas phase will dissolve in the liquid will be rate-determining. That is, the reaction amount per packed bed unit decreases. Furthermore, the decrease in the hydrogenation rate of orefin causes a dimerization of orefin or a tarification reaction due to the formation of a higher polymer. Occurs and the yield decreases.
- the gas superficial velocity is preferably 10 cm / sec or less. If the gas superficial velocity is too high than 10 cmZsec, abrasion powder is generated due to friction between the catalysts, and the pressure loss in the packed bed may increase. The gas superficial velocity is obtained by the following equation (1).
- a reactor having an inner diameter of 4 mm is charged with 12 cc of a catalyst containing copper, and a liquid containing 21% by weight of ⁇ -methylstyrene (AMS) is supplied at a rate of 48 g / min. Five moles of hydrogen were fed. The pressure was 1. OMP a G and the temperature was 200 ° C. At this time, the gas superficial velocity was 7 cm / sec, and the reaction amount of ⁇ -methylstyrene per catalyst was 49 km O IZm 3 catalyst / hr.
- AMS ⁇ -methylstyrene
- a reactor having an inner diameter of 4 mm was charged with 2.2 cc of a catalyst containing palladium, and a solution containing 18% by weight of methyl styrene (AMS) was supplied at 3.3 g / min, and the amount of supplied AMS was converted to the number of moles. 1.5 times the number of moles of hydrogen was supplied.
- the pressure was 1. OMP aG and the temperature was 180 ° C.
- the gas superficial velocity at this time was 6.5 cm / sec, and the reaction amount of permethyl styrene per catalyst was 71 km o 1 / m 3 catalyst Z hr.
- Example 2 The procedure was performed under the same conditions as in Example 1 except that the raw materials were supplied at 1.6 g / min, the reaction temperature was 210 ° C., and the pressure was 1.4 MPaG. Superficial gas velocity in this case is 2. a 7 cmZs ec, reaction of the non-methylstyrene styrene per catalyst was 14 kmo 1 Zm 3 catalyst / hr.
- Comparative Example 2 The procedure was performed under the same conditions as in Example 2 except that the raw materials were supplied at 1.6 gZmin. The gas superficial velocity at this time was 2.8 cm / sec, and the reaction amount of ⁇ -methylstyrene per catalyst was 42 kmo 1 / m 3 catalyst / hr.
- a hydrogenation reaction of an olefin which allows a liquid containing an olefin and a gas containing hydrogen to pass through a packed bed of a solid hydrogenation catalyst through an appl. And a method for hydrogenating orefin having an excellent effect that the reaction rate is high.
