Uneasily-disintegrated mixed active carbon desulfurizing agent and preparation method thereof

Abstract

The invention discloses an uneasily-disintegrated mixed active carbon desulfurizing agent and a preparation method thereof. The uneasily-disintegrated mixed active carbon desulfurizing agent is characterized by being prepared from the following raw materials in parts by weight: 90-100 parts of active carbon, 40-50 parts of diatomite, 2.5-4 parts of zinc oxide, 6-8 parts of nano bentonite, 1-2 parts of sodium alcohol ether sulphate, 3-5 parts of anthracite, 3-5 parts of limestone powder, 3-4 parts of copper sulfate, 3-4 parts of silica sol, 2.5-4 parts of propyl acetate emulsion, 2-4 parts of ammonium hydrogen carbonate, 0.5-0.8 part of potassium sorbate, 4-6 parts of an adsorption auxiliary agent and a proper amount of water. According to the uneasily-disintegrated mixed active carbon desulfurizing agent, zinc oxide, limestone and the like are added into active carbon so that the desulfurizing efficiency is enhanced; viscous matters including the silica sol, the propyl acetate emulsion and the like are added so that the strength of the active carbon is increased, and a product is not easy to disintegrate and is firm and durable; the adsorption auxiliary agent is added and has the special porosity so that the contact time between gas and the adsorption auxiliary agent is prolonged, and furthermore, the effects of inhibiting bacteria and purifying air are realized; and the uneasily-disintegrated mixed active carbon desulfurizing agent is suitable for industrial desulfurization, is also suitable for treating automobile tail gas with a good effect.

Description

technical field [0001] The invention relates to a desulfurization activated carbon and a preparation method thereof, in particular to a non-disintegrating mixed activated carbon desulfurizer and a preparation method thereof. Background technique [0002] Activated carbon with high specific surface area has a porous structure and can adsorb various organic and inorganic substances. It has the characteristics of large adsorption capacity and fast adsorption speed. field. [0003] Among the many desulfurization methods, one is activated carbon adsorption. Although activated carbon can adsorb a variety of acid gases, the price of activated carbon is relatively high, and the desulfurization efficiency is low, which increases the cost. In the present invention, activated carbon is combined with diatomite with special pores, and various functional substances are added to make granular substances, so that the desulfurizer is easy to fix, safe and non-toxic, has strong adsorption pe...
