BIOMASS GASIFICATION APPARATUS USING SUPERCRITICAL WATER AND SYSTEM INCLUDING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a gasification technology using supercritical water effectively forming fuel gas such as methane and hydrogen from biomass. PSOLUTION: The system comprises a pretreatment apparatus treating the biomass with hot water under a predetermined temperature and pressure in the presence of a non-metallic catalyst, a reactor subjecting the biomass slurry with the non-metallic catalyst obtained by the hot water treatment to a hydrothermal treatment under a predetermined temperature and pressure, a slurry feeder continuously feeding the slurry with a constant concentration from the pretreatment apparatus to the reactor, a first pressure accumulator installed between the pretreatment apparatus and the slurry feeder to accumulate pressure of the slurry to be received by the slurry feeder, and a second pressure accumulator installed between the slurry feeder and the reactor to accumulate pressure of the slurry fed from the slurry feeder.
