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

Biomass gasification gas purification system and method, and methanol production system and method

A biomass gasification gas purification system includes a dust collector for removing dust in biomass gasification gas (containing tar components) acquired by gasifying biomass by a biomass gasification furnace, a desulfurizer for removing sulfur oxide components in the dust-removed biomass gasification gas, a pre-reforming reactor for reforming tar components in the desulfurized biomass gasification gas, a steam feed unit for feeding steam to an upstream side of the pre-reforming reactor, and a natural-gas feed unit for feeding natural gas on an upstream side of the desulfurizer.

Biomass gasification gas purification system and method and methanol production system and method

Methanol is synthesized from a gas produced through gasification of biomass serving as a raw material, making use of a biomass feeding means for feeding biomass into a furnace main body and, located above the biomass feeding means, combustion-oxidizing-agent-feeding means for feeding into the furnace main body a combustion-oxidizing agent containing oxygen or a mixture of oxygen and steam.

Biomass gasifycation furnace and system for methanol synthesis using gas produced by gasifying biomass

CaS oxidation has CaS particles oxidized into CaSO completely as far as to the interior of the particle. The interior of an oxidation apparatus is partially partitioned by a partition to thereby form a first fluidized bed on the inner side, a second fluidized bed on the outer side and a space portion thereabove. A heat exchanger having a baffle plate is disposed on the inner side of the partition and an in-bed heat exchanger is disposed on the outer side of same. A desulfurizing product-containing fine powder and coarse powder and a mixture gas of nitrogen, oxygen and steam are supplied into the second fluidized bed . Also, coal and coal char are supplied into the first fluidized bed from below. Of the particles oxidized in the second fluidized bed and supplied into the first fluidized bed from below with the flow of a mixture gas , the fine powder entrains into the space portion as entrained particles and a major part thereof falls down into the second fluidized bed as particles . The completely oxidized particles are discharged as discharged ash and entrained ash
