Coal nanocatalysis medium and synthesis process thereof

Abstract

The invention discloses a preparation technology of a nanocatalysis medium for increasing coal combustion efficiency. The prepared catalysis medium is an oily liquid which is insoluble in water, has stable properties in the air, does not contain any explosive component or heavy metal component, and does not cause any damage to combustion equipment. The catalysis medium is characterized by consisting of a continuous solvent carrier phase component, a continuous solute carrier phase component, a continuous solute promoting phase component and a high-activity nanocatalysis medium dispersed phase. Due to the adoption of the coal nanocatalysis medium prepared with the technology, pulverized coal combustion can be promoted, the amount of fly ash, non-combusted carbon particles and residues is reduced, the using amount of coal is lowered, catalytic coal saving rate is up to 11-18 percent, the emission of pollutants such as Sox, NOx and the like is lowered effectively, the phenomena of cokingand skin formation in a furnace are eliminated, stable combustion of pulverized coal is promoted, the flowing activity of oxygen is increased, the utilization ratio of oxygen is increased, the introducing amount of primary air is reduced, and energy loss caused by the introduction of inert gases is lowered.

Description

technical field [0001] The invention relates to a coal nano-catalyst synthesis process, which belongs to the field of powdered coal nano-catalyst preparation. Background technique [0002] At present, the technical research in the field of coal catalytic combustion additives in foreign countries has become mature, and has been practically applied in cement, power plants, steel and chemical industries. my country's coal chemical research workers also carried out research on catalytic combustion technology of coal in the 1990s, and made a lot of gratifying progress. From the analysis of domestic and foreign patent retrieval, literature retrieval and practical application cases, it can be roughly divided into two categories: [0003] The first class of oxidation catalyst materials based on industrial salts, including MnO 2 , Fe 2 o 3 , MgCO 3 , MnCO 3 , NaCl (salt), MgCl 2 , MgO, CaO, CaF 2 , FeCl 3 , FeCl 2 And industrial waste slag containing such materials such as ...
