Title:
BIO-FUEL PRODUCTION METHOD USING FLOW-TYPE REACTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/106619
Kind Code:
A1
Abstract:
[Problem] To enable mass-production of a bio-fuel that is suitable for a diesel engine such that the free fatty acid conversion rate is high and the triglyceride conversion rate is kept low by using a flow-type reaction device in a bio-fuel production method which involves reacting a lower alcohol with a raw material oil containing a free fatty acid in the presence of a solid acid catalyst. [Solution] A bio-fuel production method performed at a lower alcohol-to-raw material oil mass ratio of 0.12 to 0.8, a reaction temperature of 170°C to 300°C, and a liquid hourly space velocity (LHSV) of 0.5 (h-1) to 6 (h-1), using as a solid acid catalyst a catalyst selected from among an SiO2/Al2O3-based solid acid catalyst, an SiO2/Al2O3-based solid acid catalyst comprising mesoporous silica having portions into which aluminum is introduced, and an Al2O3/B2O3-based solid acid catalyst.
