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

摘要

A biomass gas purification system comprises: dust removal equipment (14) that filters soot and dust in biomass gasification gas (including tar components) (13) obtained through the gasification of biomass using a biomass gasification furnace; desulfurization equipment (15) that removes sulfur oxide components in the filtered biomass gasification gas (13); a pre-reforming reactor (16) that reforms the tar components in the biomass gasification gas (13) after desulfurization; a vapor supply means (18) that supplies vapor (17) at the upstream side of the pre-reforming reactor (16); and a natural gas supply means (20) that supplies natural gas (19) at the upstream side of the desulfurization equipment (15).
