Production method of lignite gas for removal of sulfur dioxide and nitrogen oxide contained in flue gas

摘要

The present invention relates to a method for producing lignite char which is useful for removing sulfur dioxide and nitrogen oxides from noxious gas contained in flue gas discharged from a stationary source.;The method for producing lignite char according to the present invention is characterized in that the raw lignite is charged into a fluidized bed reactor and fluidized by supplying a fluidizing gas composed of nitrogen, oxygen and water, while the internal temperature of the fluidizing reactor is heated to 500 to 800C, And collecting the coal tar produced as a result of pyrolysis.;The lignite charcoal obtained by the method of the present invention has an advantage that both the desulfurization and degreasing performance are superior to those of the conventional carbon product and the production cost is economical.
