BIOMASS GASIFICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a biomass gasification method and a biomass gasification system which are capable of producing more efficiently a fuel gas from a biomass by means of a supercritical water.

SOLUTION: The method and the system are such that the first power hot water treatment apparatus performs the hot water treatment of a biomass under the conditions of a temperature in the range of 100-250°C and a pressure in the range of 0.1-4 MPa in the presence of a nonmetallic catalyst and the second power hot water treatment apparatus performs the hot water treatment of such a slurry of the above biomass as is obtained by the above hot water treatment and as contains the above nonmetallic catalyst under the conditions of a temperature of 374°C or above and a pressure of 22.1 MPa or above.
