Sulfur solidifying catalyst

Abstract

The invention provides a sulfur solidifying catalyst. The sulfur solidifying catalyst is prepared by mixing the following raw materials by weight percent: 20%-30% of glycerol, 5%-10% of sodium carbonate, 5%-15% of sodium methylallyl sulfonate, 8%-13% of sodium gluconate, 6%-15% of titanium dioxide, 2%-6% of triethanolamine and 25%-35% of water, wherein the sum of the weight percent of the raw materials is 100%. Titanium dioxide is modified to obtain nano titanium dioxide material. According to the sulfur solidifying catalyst, fire coals can be burned sufficiently, 10% or above dosages of fire coals can be reduced, the emission amount of sulfur dioxide can be reduced, 30% or above desulfurization amount can be achieved, and meanwhile, the emission amount of dust and harmful gas can be reduced.

Description

technical field [0001] The invention relates to a catalyst, in particular to a new high-efficiency sulfur-fixing catalyst which is composed of a composite functional surfactant with glycerol as a carrier and has the function of coal sulfur-fixing and denitrification. Background technique [0002] Coal is the most important energy source in my country, accounting for 70% of the total energy consumption. Although my country's coal resources are quite rich, in terms of coal quality, there are many difficult-to-separate coals in my country, and the proportion of high-ash and high-sulfur coal is large. Medium-high-sulfur coal and high-sulfur coal with a sulfur content of more than 2% in coal account for about 1 / 3 of the total reserves. Harmful gases such as SO2 and NOx and soot emitted by coal burning have caused great pollution to the atmospheric environment of our country and seriously damaged the ecological environment. [0003] The coal catalyst is a lipophilic substance, an...
