Abstract

The invention provides a method for preparing a sulphur capturing catalyst, which comprises steps: raw materials with percentage by weight comprising glycerol 20%-30%, sodium carbonate 5%-10%, sodium methallyl sulfonate 5%-15%, sodium gluconate 8%-13%, titanium dioxide 6%-15%, triethanolamine 2%-6% and water 25%-35% are weighed; the odium carbonate, the sodium methallyl sulfonate and the sodium gluconate are added into 3/4 water, are fully stirred for 50-70 hours through a stirring tank to prepare a mixed liquid A; the titanium dioxide is added into the residual 1/4 water to be stirred for 25-35 minutes through the stirring tank, and is fully stirred for 50-70 hours by further adding with the glycerol and the triethanolamine to prepare a dispersion liquid B; and the mixed liquid (b) A (/b) and the dispersion liquid (b) B (/b) are mixed to fully stir for 25-35 minutes, thereby preparing the sulphur capturing catalyst. The sulphur capturing catalyst which is made through the method for preparing the sulphur capturing catalyst enables coal to be more fully burnt, can reduce coal usage above 10%, reduces above 30% emission of sulfur dioxide and desulfurization, and reduces emission of dust and harmful gas simultaneously.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a method for preparing a novel high-efficiency sulfur-fixing catalyst which is composed of a composite functional surfactant with glycerol as a carrier and has coal sulfur-fixing and denitrification functions. 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 co...
