Problems solved by technology

At present, the terminal utilization efficiency of coal in my country is about 41%, and the efficiency of coal combustion is low, resulting in a large waste of energy.
A large amount of coal combustion causes air pollution, and a large amount of coal emissions include CO, VOC, and NO x , SO x , particles and other harmful pollutants, causing serious air pollution, carbon emissions greatly exceed the standard, and a direct threat to the human living environment

Embodiment 1

[0028] A kind of coal combustion catalyst, is made of the raw material of following percentage by weight:

[0029]

[0030] Add diethanol monoisoalcoholamine, triethanolamine and polyoxyethylene octylphenol ether into the reaction kettle and stir for 30 minutes, then add papermaking black liquor and sugar factory waste liquor, stir and mix thoroughly, and then add sodium chloride and La 2 o 3 , while continuing to stir, the reactor was heated to 40° C. for 3.5 hours to obtain the desired coal combustion catalyst. Before the catalyst leaves the factory, performance testing should be carried out according to enterprise standards and relevant national and industry standards, including pulverized coal combustion experiments and physical and chemical performance tests of cement. Products that pass the inspection can leave the factory.

Embodiment 2

[0032] A kind of coal combustion catalyst, is made of the raw material of following percentage by weight:

[0033]

[0034] Add diethanol monoisoalcoholamine, triethanolamine and polyvinylpyrrolidone into the reaction kettle and stir for 35 minutes, then add papermaking black liquor and sugar factory waste liquor, stir and mix thoroughly, and then add potassium chloride and Y 2 o 3 , while continuing to stir, the reactor was heated to 50° C. for 3 hours to obtain the desired coal combustion catalyst. Before the catalyst leaves the factory, performance testing should be carried out according to enterprise standards and relevant national and industry standards, including pulverized coal combustion experiments and physical and chemical performance tests of cement. Products that pass the inspection can leave the factory.

Embodiment 3

[0036] A kind of coal combustion catalyst, is made of the raw material of following percentage by weight:

[0037]

[0038] Add diethanol monoisoalcoholamine, triethanolamine and polyoxyethylene octylphenol ether into the reaction kettle and stir for 40 minutes, then add papermaking black liquor and sugar factory waste liquor, stir and mix thoroughly, filter and then add sodium chloride and LaMnO 3 , heating the reactor to 60° C. for 2.5 hours while continuing to stir, and the desired coal combustion catalyst can be prepared. Before the catalyst leaves the factory, performance testing should be carried out according to enterprise standards and relevant national and industry standards, including pulverized coal combustion experiments and physical and chemical performance tests of cement. Products that pass the inspection can leave the factory.

Abstract

The invention relates to the technical field of coal energy, and discloses a coal combustion catalyst, which is prepared by the following raw materials in percentage by weight: 13-22% of diethanol monoisopropanol amine, 25-35% of triethanolamine, 10-15% of non-ionic surfactant, 13-20% of papermaking black liquid, 15-20% of sugar refinery waste liquid, 1-6 parts of alkaline metal salt, and 0.2-0.8% of rare earth element compounds. The performances of the coal catalyst can be mainly optimized, the cost is lowered, the firing point and after-combustion temperature of the coal can be reduced by the coal combustion catalyst, the combustion speed of the coal can be increased, and coal is thoroughly combusted, so that not only the coal consumption and cost be reduced, but also the emission of SO2, NOx and other harmful gases can be reduced, and the coal combustion catalyst can provide favorable conditions for combusting inferior coal instead of high-quality coal.

Description

technical field [0001] The invention relates to the technical field of coal energy, in particular to a coal combustion catalyst. Background technique [0002] With the acceleration of industrialization and urbanization and the continuous upgrading of the consumption structure, my country's energy demand is growing rigidly. Due to the constraints of domestic resource guarantee capacity and environmental capacity, as well as the impact of global energy security and climate change response, resource and environmental constraints are increasingly strengthened. my country is a country that uses coal as the main energy source. Coal consumption accounts for about 70% of energy consumption. The large-scale use of coal has brought about two major problems: one is energy efficiency, and the other is environmental problems. At present, the terminal utilization efficiency of coal in my country is about 41%. The efficiency of coal burning is low and the waste of energy is huge. A large ...
