Abstract

The invention discloses an efficient fuel sulfur removing agent and a preparation method thereof, and belongs to the field of energy conservation and environmental protection. According to the efficient fuel sulfur removing agent, octadecyl dimethyl (3-methoxysilyl propyl) ammonium chloride serves as a template agent, raw materials such as sodium hydroxide and sodium metasilicate are added, mixture is re-crystallized to obtain catalytic carriers of porous molecular sieves, the catalytic carriers have more adsorption sites, sulfur-containing compounds are adsorbed, so that sulfur removing and sulfur fixing functions of a catalyst on the sulfur-containing compounds are facilitated, sodium tungstate serves as a raw material, a strong oxide is formed and can oxidize sulfides, sufficient burning and sulfur removing of fuel is facilitated, a sulfur removing catalyst function body is formed, the sulfur removing agent has regeneration activity, the cost of the sulfur removing agent is reduced,the sulfur removing agent can be reused, carbide slag, blast furnace slag and limestone are added and compounded, sulfur is effectively fixed, decomposing of a sulfur fixing product is prevented, andsulfur fixing effects are facilitated. The sulfur removing agent solves the problem of poor sulfur removing and sulfur fixing effects of current fuel.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a high-efficiency fuel desulfurizer and a preparation method thereof. Background technique [0002] With the development of science and technology, although a variety of new energy sources emerge in endlessly, the current energy situation determines that the energy structure will still be dominated by coal in the next 30 years, and the coal consumed by combustion accounts for more than 80% of the total coal consumption every year. Sulfur dioxide and nitrogen oxides produced by coal burning are discharged into the atmosphere, causing serious pollution to humans and the ecological environment. Current annual SO emissions 2 More than 20.9 million tons, of which 90% of sulfur dioxide comes from coal combustion, the direct combustion of coal is the root cause of serious air pollution. A considerable portion of coal in coal reserves is h...
