- boric acid is contained in an amount of less than 0.005 wt%, the electronic charge density of the active metal may be decreased to reduce the amount of hydrogen adsorption and ultimately decrease the catalytic activity. If the amount of boric acid exceeds 0.1 wt% The excess amount of boric acid is dissolved in the target product, which may cause a problem in the quality of the product, so that the above range is suitable.
- sucrose (Aldrich) is added to distilled water (10 ml) and stirred using a magnetic stirrer. After sucrose was completely dissolved in distilled water, 0.2 g of boric acid (Aldrich) was added and dissolved in the aqueous sucrose solution for 2 hours. Then, the solution was supported on a SiO 2 -Al 2 O 3 carrier by an incipient-wetness impregnation method.
- Example 2 A noble metal ruthenium-tin was loaded on a C-SiO 2 -Al 2 O 3 carrier
- This catalyst contains ruthenium in an amount of 5 parts by weight based on 100 parts by weight of a C-SiO 2 -Al 2 O 3 carrier.
- the ruthenium is supported at the same mole number as that of ruthenium and reduced (100 cc / min H 2 : 30 / N 2 : 70) and used as a catalyst for dicarboxylic acid hydrogenation reaction.
- the amount of the reactant relative to the reaction solvent was fixed to 7 wt%.
- the reactor was pressurized to the reaction pressure using hydrogen, the reactor was leaked through the hydrogen sensor, and then the reactor was evacuated and purged to remove all of the oxygen in the reactor.
- the internal pressure of the reactor was adjusted to 10 bar, and then the internal temperature of the reactor was heated to the reaction temperature.
- the reaction was conducted at 230 ° C and 90 bar for 6 hours.
- the stirring was maintained at 1000 rpm using an overhead impeller.
- the catalyst and the liquid product were separated by filtration and analyzed by gas chromatography equipped with HP-1 column. The conversion, selectivity, and yield of CHDM, CHMA, and ester produced according to CHDA conversion were calculated using the following equations (1) to (3).
- the Ru-Sn / SiO 2 -Al 2 O 3 catalyst was prepared by the same method except that the carbon in Example 1 was coated.
- ruthenium was supported on 5 parts by weight based on 100 parts by weight of the SiO 2 -Al 2 O 3 support.
- the amount of tin was supported at the same mole number as that of ruthenium, and reduced (100 cc / min H 2 : 30 / N 2 : 70) and used as a catalyst for dicarboxylic acid hydrogenation reaction.
- FIG. 3 shows the comparison of the initial reaction activity after hydrothermal treatment of the catalyst for 60 hours under the reaction conditions to confirm the hydrothermal stability of the Ru-Sn / SiO 2 -Al 2 O 3 catalyst.
- the Ru-Sn / SiO 2 -Al 2 O 3 catalyst showed an excellent initial activity as in the case of the Ru-Sn / C-SiO 2 -Al 2 O 3 catalyst, but the reaction activity greatly decreased after exposure to the hydrothermal conditions for 60 hours .
- the Ru-Sn / C-Al 2 O 3 catalyst was tested for the performance and durability of the Ru-Sn / C-SiO 2 -Al 2 O 3 catalyst by replacing the SiO 2 --Al 2 O 3 support with an Al 2 O 3 support ≪ / RTI > Catalyst preparation was carried out the same except for changing the method for producing the C-2 -Al 2 O 3 carrier of SiO in Example 1, a SiO 2 -Al 2 O 3 to Al 2 O 3.
- sucrose (Aldrich) was added to 10 ml of distilled water and stirred using a magnetic stirrer. The sucrose was completely dissolved in distilled water, and 0.2 g of boric acid (Aldrich) was added thereto and dissolved in the aqueous solution of sucrose for 2 hours. Then, the solution was supported on an Al 2 O 3 carrier by an incipient-wetness impregnation method.
- the complexes carbonized the coated sucrose via a carbonization press.
- the carbonization was processed at 300 °C 3 hours, wherein sucrose through the dehydration between the hydroxyl group of Al 2 O 3 surface with sucrose is sticking to the Al 2 O 3 surface. After the carbonization at 500 ° C for 3 hours, the sucrose attached to the surface turns into a polycyclic aromatic carbon sheet. Nitrogen was flowed at 100 cc / min in the carbonization process and the ramping rate was 5 ° C / min.
- the catalyst contained ruthenium in an amount of 5 parts by weight based on 100 parts by weight of the C-Al 2 O 3 support.
- the amount of tin was supported at the same mole number as that of ruthenium, and reduced (100 cc / min H 2 : 30 / N 2 : 70) and used as a catalyst for dicarboxylic acid hydrogenation reaction.
