Abstract
The present disclosure provides a novel and practical alcohol and derivatives thereof which have more industrial value than existing petrochemical raw materials. The present disclosure further provides ethanol, characterized in that a peak in gas chromatography measured by gas chromatograph mass spectrometry (GC/MS) has at least one peak with a retention time selected from (A) a peak of 5 minutes 25 seconds to 5 minutes 35 seconds and two peaks of 2 minutes 55 seconds to 3 minutes 5 seconds; (B) a peak of 12 minutes 30 seconds to 12 minutes 40 seconds; (C) a peak of 6 minutes 36 seconds to 6 minutes 45 seconds; and (D) a peak of 15 minutes 00 seconds to 15 minutes 15 seconds.
Claims18
A method for manufacturing ethanol, comprising:
- a step of converting a carbon source derived from waste by combustion and/or partial combustion into a synthetic gas comprising carbon monoxide and hydrogen;
- a step of purifying the synthetic gas;
- a microbial fermentation step of supplying the synthetic gas comprising carbon monoxide and hydrogen to a microbial fermentation tank to obtain an ethanol-containing liquid by microbial fermentation;
- a separation step of separating the ethanol-containing liquid into a liquid or solid component containing microorganisms and a gas component containing ethanol;
- a liquefaction step of condensing and liquefying the gas component;
- a purification step of purifying ethanol from the liquid obtained in the liquefaction step;
- wherein the purified ethanol is characterized in that the retention time has at least one peak selected from the group consisting of the following (A) to (D) in gas chromatography measured by gas chromatograph mass spectrometry (GC/MS):
- (A) a peak of 5 minutes 25 seconds to 5 minutes 35 seconds and two peaks of 2 minutes 55 seconds to 3 minutes 5 seconds;
- (B) a peak of 12 minutes 30 seconds to 12 minutes 40 seconds;
- (C) a peak of 6 minutes 36 seconds to 6 minutes 45 seconds;
- and
- (D) a peak of 15 minutes 00 seconds to 15 minutes 15 seconds.
