[0027] (2) Add sodium carbonate, sodium methacrylate, and sodium gluconate to 3 / 4 of the water, and stir fully with a stirring tank for 50 hours to obtain a mixed solution A;

[0028] (3) Add titanium dioxide to the remaining 1 / 4 of the water and stir with a stirring tank for 35 minutes, then add glycerol and triethanolamine and stir for 70 hours to obtain dispersion B;

[0029] (4) Mix the mixed liquid A and the dispersion liquid B and stir them thoroughly for 25 minutes to prepare the sulfur-fixing catalyst.

Embodiment 3

[0031] A kind of sulfur-fixing catalyst, is made from following raw material and method:

[0032] (1) Weigh the following raw materials by weight: 350 parts of water, 300 parts of glycerol, 115 parts of sodium carbonate, 150 parts of sodium methacrylate, 160 parts of sodium gluconate, 180 parts of titanium dioxide, and 80 parts of triethanolamine.

[0033] (2) Add sodium carbonate, sodium methacrylate, and sodium gluconate to 3 / 4 of the water, and stir fully with a stirring tank for 70 hours to obtain a mixed solution A;

[0034] (3) Add titanium dioxide to the remaining 1 / 4 of the water and stir with a stirring tank for 25 minutes, then add glycerol and triethanolamine and stir for 50 hours to obtain dispersion B;

[0035] (4) Mix the mixed liquid A and the dispersion liquid B and stir them thoroughly for 35 minutes to prepare the sulfur-fixing catalyst.

Abstract

The invention provides a sulfur-fixing catalyst, which is formed by mixing the following raw materials in mass percentage: 20%-30% of glycerol, 5%-10% of sodium carbonate, 5%-15% of sodium methacrylate, gluconic acid Sodium 8%-13%, titanium dioxide 6%-15%, triethanolamine 2%-6%, water 25%-35%. The sum of the mass percentages of the above components satisfies 100%, and the titanium dioxide is a nano titanium dioxide material obtained after modification treatment. The sulfur-fixing catalyst of the invention can make coal burn more fully, reduce coal consumption by more than 10%, reduce sulfur dioxide emission and desulfurization by more than 30%, and simultaneously reduce dust and harmful gas emission.

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...
