DUAL BIOMASS GASIFICATION REACTOR HAVING NICKEL DISTRIBUTION PLATE AND BIOMASS GASIFIER HAVING SAME

摘要

Disclosed is a dual biomass gasification reactor and a biomass gasifier having the dual biomass gasification reactor, and the reactor comprises: a first reactor which gasifies injected biomass using an external heat source and the oxidation heat source of the biomass, and in which sand or a tar pyrolysis catalyst is filled and moves along with the flow of the external heat source so as to gasify the biomass and to produce bio-char; a second reactor which is provided to communicate with the first reactor so as to use the heat sources of the first reactor and is filled with a carbon adsorbent so as to decrease the content of the tar in the gas produced in the first reactor and to increase hydrogen production for the supply of the gas to a subsequent process; and a distribution plate which is disposed in the communication portion between the first and second reactors so as to prevent the movement of the bio-char and the sand or the tar pyrolysis catalyst in the first reactor towards the second reactor and to prevent the leakage of the carbon adsorbent in the second reactor towards the first reactor, wherein the distribution plate is a nickel plate. When the dual biomass gasification reactor of the present invention and the biomass gasifier having the same are used, gas production from the biomass can be economically and effectively obtained with minimized amounts of tar and ammonia.
