A first reactor for gasifying the injected biomass using an external heat source and an oxidizing heat source of the biomass itself, wherein a sand or tar decomposition catalyst is filled therein and flows along the air stream of the external heat source, A first reactor for gasifying and producing a bio-char; The first reactor is connected to the first reactor and uses the heat source of the first reactor. The carbon adsorbent is filled in the first reactor, thereby reducing the content of tar in the product gas generated in the first reactor and increasing the production of hydrogen. A second reactor for supplying the reactants; And a distribution plate disposed in a communicating portion between the first and second reactors, wherein the distribution plate shields the flow of the bichar and the sand or tar decomposition catalyst in the first reactor toward the second reactor, A dual biomass gasification reactor and a biomass gasification apparatus comprising the gasification reactor are disclosed, wherein the dual biomass gasification reactor comprises a distribution plate for preventing the carbon adsorbent from flowing out toward the first reactor, and the distribution plate is a nickel plate. Using the dual biomass gasification reactor of the present invention and the biomass gasification apparatus having the dual biomass gasification reactor, it is possible to economically and efficiently produce the product gas from which the tar and ammonia contents are minimized from the biomass. |
