Production method of desulfurized and denitrated active carbon

Abstract

The invention discloses a production method of desulfurized and denitrated active carbon and relates to the field of production of active carbon. The production method comprises the following steps: firstly mixing and grinding coking coal and coke powder according to a specific ratio, grinding to certain fineness, wherein the passing rate of the coal powder is 85% or above when the coal powder passes through a 200-mesh sieve generally; then mixing the coal powder with tar and water according to a certain ratio, carrying out heat preservation, heating and kneading, adding a product, obtained after the added tar and water and coal powder are fully infiltrated, permeated and uniformly dispersed, into a hydraulic press, extruding the product into a fixed wet carbon finished product by using acertain die under certain pressure; naturally drying and airing qualified carbon bars, then carbonizing by using a carbonizing furnace according to the property requirements of different active carbons, and activating the carbonized material by an activation furnace, thus finally obtaining the desulfurized and denitrated active carbon which can meet different requirements on physical and chemicalproperties. The production method of desulfurization and denitration active carbon is capable of firstly producing qualified molded products, then carbonizing and activating the molded products to produce the qualified desulfurized and denitrated active carbon product; the production qualification rate of the desulfurized and denitrated active carbon is increased.
