Description

Technical Field

[0001] The present application relates to the technical field of coal-based new energy, and in particular to a coal-fired catalyst. Background Art

[0002] At present, the domestic coal-fired catalyst industry is thriving. The main way for enterprises to save energy in coal-fired combustion is to mix potassium peroxide, potassium chlorate, sodium nitrate and other substances into the coal. These substances can release oxygen during the heating process. This mode can increase the oxygen supply in the combustion process, thereby achieving the purpose of increasing the burnout rate and thus improving thermal efficiency. However, this method not only has a high investment cost, but also with the development of combustion equipment, new combustion equipment can make the coal burnout rate reach more than 95%. This type of coal-saving product can no longer meet the needs of coal saving, consumption reduction, environmental protection, and economic development. Therefore, it is urgent to develop a coal-fired catalyst with high thermal efficiency and environmental protection. Summary of the invention

[0044] Performance testing 1. Combustion thermal efficiency: Add coal-fired catalyst when burning coal, and then measure the combustion thermal efficiency according to the "Coal-fired Industrial Boiler Thermal Efficiency Test Program".

[0045] (2) Nitrogen oxide emission: A coal-burning catalyst is added during coal combustion, and then a gas analyzer is used to test the nitrogen oxide gas emission during coal combustion.

[0046] Table 1 Performance test results of coal-fired catalyst sample Combustion thermal efficiency (%) Nitrogen oxide emission (kg / t) Example 1 70.1 1.63 Example 2 74.2 1.42 Example 3 74.7 1.42 Example 4 74.6 1.45 Example 5 70.9 1.59 Example 6 76.2 1.35 Example 7 75.3 1.40 Example 8 76.3 1.35 Example 9 76.3 1.32 Example 10 78.5 1.31 Embodiment 11 77.3 1.32 Example 12 77.6 1.35 Embodiment 13 78.7 1.12 Comparative Example 1 65.2 1.83 Comparative Example 2 67.3 6.13 In combination with Example 1 and Comparative Examples 1-2, the combustion thermal efficiency of the coal-fired catalyst in Example 1 is higher, and the emission of nitrogen oxides gas is less. It can be seen that when preparing the coal-fired catalyst, adding lanthanum oxide-loaded activated carbon and desulfurizer at the same time can not only play a good combustion-supporting role and improve the combustion thermal efficiency, but also reduce the emission of nitrogen oxides gas.

[0047] Combined with Examples 1-5, the combustion thermal efficiency of the coal-fired catalyst in Examples 2-4 is higher, and the emission of nitrogen oxides is lower. It can be seen that when preparing the combustion-supporting filler, the ratio of lanthanum oxide to activated carbon is preferably 1: (40-50), and the performance of the obtained combustion-supporting filler is better.

[0048] Combining Example 3, Example 6 and Example 7, the coal-fired catalyst in Example 6 has the highest combustion thermal efficiency and the least emission of nitrogen oxide gas. It can be seen that when preparing the combustion-supporting filler and drying the precipitate, the drying conditions for the precipitate in Example 6 are optimal.

[0049] Combining Example 6, Example 8 and Example 9, the combustion thermal efficiency and the emission of nitrogen oxide gas of the coal-fired catalyst in Example 6, Example 8 and Example 9 are not much different. It can be seen that when preparing the coal-fired catalyst, increasing the amount of raw materials used has little effect on the performance of the prepared catalyst.

[0050] In combination with Example 8 and Examples 10-12, the combustion thermal efficiency of the coal-fired catalyst in Example 10 is the highest. It can be seen that when preparing the coal-fired catalyst, a composition consisting of [1,1'-bis(diphenylphosphino)ferrocene]palladium dichloride dichloromethane complex and hydrogen peroxide is added to the raw material. The combination of [1,1'-bis(diphenylphosphino)ferrocene]palladium dichloride dichloromethane complex and hydrogen peroxide can further improve the combustion thermal efficiency of the coal-fired catalyst.

[0051] Combining Example 10 and Example 13, the emission of nitrogen oxide gas in Example 13 is relatively small. It can be seen that when preparing the coal-fired catalyst, adding biomass particles to the raw materials and burning the biomass particles with coal are beneficial to reducing the emission of nitrogen oxide gas.
