BIOMASS GASIFICATION GAS PURIFICATION SYSTEM AND METHOD, AND METHANOL PRODUCTION SYSTEM AND METHOD

摘要

A biomass gasification gas purification system has a dust removal apparatus (14) for filtering soot and dust from biomass gasification gas (including tar component) (13) obtained through the gasification of the biomass using a biomass gasification furnace, a desulfurization apparatus (15) for removing sulfur oxide component in the filtered biomass gasification gas (13), first to third pre-reformation reactors (16A to 16C) that provide pre-reforming catalyst for reforming the tar component in the biomass gasification gas (13) after desulfurization, and first and second coolers (17A and 17B) that are interposed between the first to third pre-reformation reactors (16A to 16C) for cooling the reformed gas.
