Abstract

The present invention provides an apparatus and a method which are suitable for producing an organic substance using a synthesis gas from a waste gasification furnace. The apparatus 1 for producing an organic substance from waste comprises a synthesis gas generation furnace 11 for generating a synthesis gas by partial oxidation of the waste; and an organic substance production unit 12 for producing an organic substance from the synthesis gas. The organic substance production unit 12 further comprises: a synthesis unit 13 for synthesizing an organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst, and a fermenter 14 for producing an organic substance by subjecting the synthesis gas to microbial fermentation.

First claim

1 . An apparatus for producing an organic substance from waste, comprising:
a synthesis gas generation furnace for generating a synthesis gas by partial oxidation of the waste; and an organic substance production unit for producing an organic substance from the synthesis gas, the organic substance production unit further comprising: a synthesis unit for synthesizing an organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst, and a fermenter for producing an organic substance by subjecting the synthesis gas to microbial fermentation.

2 . The apparatus according to claim 1 , wherein the fermenter is connected downstream of the synthesis unit.

3 . The apparatus according to claim 1 , wherein the organic substance is ethanol.

4 . The apparatus according to claim 1 , wherein the organic substance synthesized in the synthesis unit and the organic substance produced in the fermenter are different from each other.

5 . An apparatus for producing an organic substance from waste, comprising:
a synthesis gas generation furnace for generating a synthesis gas by partial oxidation of the waste; and an organic substance production unit for producing an organic substance from the synthesis gas, the organic substance production unit further comprising: a synthesis unit for synthesizing a first organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst, and a fermenter for producing a second organic substance by subjecting the first organic substance to microbial fermentation, the fermenter being connected in series to the synthesis unit.

6 . The apparatus according to claim 5 , wherein:
the first organic substance is at least one substance selected from the group consisting of alcohols having 6 or less carbon atoms, aldehydes having 6 or less carbon atoms, and carboxylic acids having 6 or less carbon atoms, and the second organic substance is at least one substance selected from the group consisting of alcohols, organic acids, fatty acids, fats and oils, ketones, dienes, biomass and saccharides.

7 . A method for producing an organic substance from waste, comprising:
a synthesis gas-generating step for generating a synthesis gas by partial oxidation of waste; and an organic substance-producing step for producing an organic substance from the synthesis gas, the organic substance-producing step further comprising: a synthesizing step for synthesizing an organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst in a synthesis unit; and a fermentation step for producing an organic substance by subjecting the synthesis gas to microbial fermentation in a fermenter.

8 . The method according to claim 7 , wherein the fermentation step is performed after the synthesizing step.

9 . The method according to claim 7 , wherein the organic substance is ethanol.

10 . The method according to claim 7 , wherein, the organic substance synthesized in the synthesizing step and the organic substance produced in the fermentation step are different from each other.

11 . A method for producing an organic substance from waste, comprising:
a synthesis gas-generating step for generating a synthesis gas by partial oxidation of waste; and an organic substance-producing step for producing an organic substance from the synthesis gas, the organic substance-producing step further comprising: a synthesizing step for synthesizing a first organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst in a synthesis unit; and a fermentation step for producing a second organic substance by subjecting the first organic substance to microbial fermentation in a fermenter which is connected in series to the synthesis unit.

12 . The method according to claim 11 , wherein:
the first organic substance is at least one substance selected from the group consisting of alcohols having 6 or less carbon atoms, aldehydes having 6 or less carbon atoms and carboxylic acids having 6 or less carbon atoms, and the second organic substance is at least one substance selected from the group consisting of alcohols, organic acids, fatty acids, fats and oils, ketones, dienes, biomass and saccharides.

13 . The apparatus according to claim 2 , wherein the organic substance is ethanol.

14 . The apparatus according to claim 2 , wherein the organic substance synthesized in the synthesis unit and the organic substance produced in the fermenter are different from each other.

15 . The method according to claim 8 , wherein the organic substance is ethanol.

16 . The method according to claim 8 , wherein, the organic substance synthesized in the synthesizing step and the organic substance produced in the fermentation step are different from each other.
