Title:
METHOD AND APPARATUS FOR PRODUCING ETHANOL
Document Type and Number:
WIPO Patent Application WO/2013/103111
Kind Code:
A1
Abstract:
Provided are a method and apparatus that efficiently saccharify and ferment hemicellulose contained in woody materials and the like and produce ethanol that can be converted into biomass ethanol. Pressurized hot water is caused to act on a biomass, the hemicellulose contained in the biomass is selectively degraded, a solid acid catalyst is caused to act on the degradation product at a temperature of 90-110°C, and a saccharified product containing xylose is obtained. Microorganisms having the ability to ferment xylose are caused to act on the resulting saccharified product, and ethanol is produced.
