Abstract

The invention discloses a desulfurization assistant. The desulfurization assistant is prepared from the following components in parts by weight: 10-20 parts of sodium hypochlorite, 5-10 parts of potassium hypochlorite, 10-12 parts of ammonium persulfate, 2-6 parts of sodium glycollate, 5-8 parts of potassium acetate, 5-8 parts of sodium citrate, 3-10 parts of ethylenediamine tetraacetic acid, 2-6 parts of potassium permanganate, 2-5 parts of formic acid, 5-10 parts of sodium carboxymethyl cellulose, 5-10 parts of benzoic acid, 2-5 parts of potassium dichromate, 3-5 parts of urea, 2-5 parts of polyacrylamide, 2-5 parts of alcohol, 0.1-0.5 part of sodium dodecyl benzene sulfonate, 0.2-0.8 part of Twain 20 and 150-200 parts of water. The desulfurization assistant disclosed by the invention has the advantages of being good in desulfurization effect and free of environment pollution.

Description

technical field [0001] The invention relates to an auxiliary agent, in particular to a desulfurization auxiliary agent. Background technique [0002] Sulfur in coal usually exists in the state of organic sulfur and inorganic sulfur. The composition structure of organic sulfur is very complex, and the main forms are mercaptan, thioether, disulfide, thioquinone and thiophene in heterocyclic state; organic sulfur mainly comes from coal-forming plants [0003] protein and microbial protein; the sulfur content in protein is 0.3% to 2.4%, and the total sulfur content is generally less than 0.5% [0004] Most of the following coals are generally dominated by organic sulfur. Inorganic sulfur in coal mainly comes from various sulfur compounds in minerals and [0005] Small amount of sulfates. The difficulty of sulfur removal in sulfide is related to the particle size and distribution state of sulfide, and the larger particle size [0006] It can be removed by washing method, and...
