Desulfurizer

Abstract

The invention discloses a desulfurizer which is composed of subcarbonate, silica and accessory ingredient. Based on the total weight of the desulfurizer, the desulfurizer comprises, in percentage by weight, 50-97 wt% of subcarbonate, 2.5-20 wt% of silica and 0.1-30 wt% of accessory ingredient, wherein the subcarbonate is at least one of basic cupric carbonate and basic zinc carbonate, and the accessory ingredient is at least one of alumina and attapulgite powder. The desulfurization (H2S) precision of the desulfurizer can be less than 0.05mg / M3, and sulphur content is about 20% (Wt / Wt). Because the raw material does not need high-temperature decomposition, energy consumption can be greatly lowered by more than 50%, thus obtaining the purpose of energy saving and emission reduction.

Description

technical field [0001] The invention relates to a desulfurization agent, in particular to a desulfurization agent with high desulfurization precision, high sulfur capacity and arsenic removal effect. Background technique [0002] The traditional desulfurizer is to decompose the basic carbonate at high temperature, and then the finished product is obtained after extruding, drying and high-temperature roasting. mg / M 3 , the sulfur capacity is generally about 10% (Wt / Wt), and its raw material basic carbonate needs pyrolysis, so it consumes more energy. Contents of the invention [0003] In order to solve the above problems, the invention provides a desulfurizing agent whose desulfurization (H 2 S) The accuracy can be less than 0.05mg / M 3 , the sulfur capacity is about 20% (Wt / Wt), and since the raw materials do not need pyrolysis, the energy consumption is greatly reduced, and the energy consumption can be reduced by more than 50%, so as to achieve the purpose of energy sa...
