Fire coal catalyst as well as preparation method and application thereof

The invention relates to the field of catalyst preparation, and discloses a fire coal catalyst and a preparation method and application thereof. The fire coal catalyst comprises the following components: sodium chloride, potassium salt, transition metal oxide, limestone and sodium citrate. When the fire coal catalyst is applied to fire coal, the ignition point of coal can be reduced, the combustion efficiency of the coal is improved, meanwhile, combustibles in fly ash and slag are reduced, and effective desulfurization is achieved. The fire coal catalyst is applied to the field of fire coal, the heat release rate of coal can be increased, and emission of pollutants is reduced. 本发明涉及催化剂制备领域，公开了一种燃煤催化剂及其制备方法和应用。该燃煤催化剂含有以下成分：氯化钠、钾盐、过渡金属氧化物、石灰石以及柠檬酸钠。该燃煤催化剂应用于燃煤中，可以降低煤炭着火点、提高煤炭燃烧效率，同时减少飞灰和炉渣中的可燃物并有效脱硫。将该燃煤催化剂应用于燃煤领域，可以提高煤炭放热率，减少污染物质的排放。
