Coal-fired catalyst as well as preparation method and application thereof

Abstract

The invention relates to the technical field of coal energy, in particular to a coal-fired catalyst as well as a preparation method and application thereof. The coal-fired catalyst is prepared from the following raw materials in percentage by weight: 10-13% of inorganic acid, 3-6% of a catalytic component, 0.3-0.5% of a sulfur-fixing component and the balance of a solvent, and the catalytic component is selected from one or more of alkali metal oxide, transition metal oxide and rare earth metal oxide. According to the coal-fired catalyst provided by the applicant, by controlling the types andthe use amounts of the coal-fired catalysts, the coal combustion rate and burn-off rate can be increased, and the heat value generated by coal combustion can be increased; and by controlling the proportion of the coal-fired catalyst and the inorganic acid, catalytic components can be promoted to be adsorbed in coal, the utilization rate of the catalyst can be increased, and the application range of the coal-fired catalyst can be expanded. The coal-fired catalyst can be applied to multiple technical fields such as cement production or coal power.

Description

technical field [0001] The invention relates to the technical field of coal energy, more specifically, the invention relates to a coal-burning catalyst and its preparation method and application. Background technique [0002] With the development of the economy, China's demand for energy is also increasing year by year. Coal accounts for about 70% of the energy consumption structure and is the main source of air pollution in China. Although the emission concentration of coal-burning air pollutants is not high, but The amount of emissions is huge, accounting for more than 70% of the total emissions of air pollutants from several of the most important energy sources in my country. In addition to environmental pollution, the extensive use of coal has also brought about problems such as low efficiency. Adding a coal-fired catalyst to coal that can catalyze coal combustion and form a chemical reaction with coal ash can form a new exothermic system, catalyze coal combustion, and im...
