Abstract

The metal-supported zeolite for alcoholic beverages of the present invention is a zeolite that carries a metal component, wherein the metal component is silver, and the zeolite is at least one selected from a beta-type one and a Y-type one. The metal-supported zeolite is for removing unwanted components contained in alcoholic beverages.

First claim

The invention claimed is:

1. A method for purifying a distilled alcoholic beverage, comprising:
providing a distilled alcoholic beverage containing at least one unwanted component selected from the group consisting of dimethyl sulfide, dimethyl disulfide, dimethyl trisulfide, and pyridine; and
passing the distilled alcoholic beverage through a metal-supported zeolite at a liquid-hourly space velocity (LHSV) of from 0.1 h −1 to 100 h −1 , such that the at least one unwanted component is removed from the distilled alcoholic beverage,
wherein the metal-supported zeolite comprises a zeolite having silver supported on the zeolite, where the zeolite is beta-type, Y-type, or both.

2. The method according to claim 1 , wherein an amount of the silver supported on the zeolite is 5% by mass to 25% by mass relative to a total amount of the metal-supported zeolite.

3. The method according to claim 2 , wherein the amount of the silver supported on the zeolite is 5% by mass to 20% by mass relative to the total amount of the metal-supported zeolite.

4. The method according to claim 1 , wherein the distilled alcoholic beverage is whisky.

5. The method according to claim 1 , wherein the distilled alcoholic beverage is rum.

6. The method according to claim 1 , wherein the distilled alcoholic beverage is whisky, brandy, gin, vodka, tequila, or rum.

7. The method according to claim 1 , wherein the zeolite has a BET specific surface area of 500 m 2 /g to 900 m 2 /g.

8. The method according to claim 1 , wherein the zeolite has a BET specific surface area of 550 m 2 /g to 850 m 2 /g.

9. The method according to claim 1 , wherein the metal-supported zeolite further comprises a binder component.

10. The method according to claim 9 , wherein an amount of the binder component is 5% by mass to 50% by mass based on a total amount of the metal-supported zeolite.

11. The method according to claim 9 , wherein the binder component is at least one selected from the group consisting of alumina, silica and clay mineral.

12. The method according to claim 1 , wherein the at least one unwanted component is selected from the group consisting of dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide.

13. The method according to claim 1 , wherein, in the passing, the distilled alcohol beverage is passed through the metal-supported zeolite at the liquid-hourly space velocity (LHSV) of from 0.5 h −1 to 50 h −1 , such that the at least one unwanted component in the distilled alcoholic beverage is removed.

14. The method according to claim 1 , wherein, in the passing, the distilled alcoholic beverage is passed through the metal-supported zeolite at the liquid-hourly space velocity (LHSV) of from 1 h −1 to 30 h −1 , such that the at least one unwanted component in the distilled alcoholic beverage is removed.

15. The method according to claim 1 , wherein an amount of the silver supported on the zeolite is 6% by mass to 20% by mass relative to a total amount of the metal-supported zeolite.

16. The method according to claim 1 , wherein a micropore volume of the zeolite is 0.05 cc/g to 0.40 cc/g.

17. The method according to claim 1 , wherein a micropore volume of the zeolite is 0.10 cc/g to 0.35 cc/g.

18. The method according to claim 1 , wherein the silver is in the form of an ion and supported inside a crystal of the zeolite.

19. The method according to claim 1 , wherein, in the passing, the distilled alcohol beverage is passed through the metal-supported zeolite such that 4% or less of an alcohol component is removed from the distilled alcoholic beverage based on an amount of the alcohol component in the distilled alcoholic beverage before the passing.
