Coal combustion composite nanometer catalyst

Abstract

A coal combustion composite nanometer catalyst consists of a catalyst, a promoter, a dispersing agent and a penetrating agent, wherein the catalyst accounts for 1-10%, the dispersing agent accounts for 0.1-0.5%, the dispersing agent accounts for 0.1-1%, and the penetrating agent accounts for 90-99%. The adding ratio is 1 to 3000, namely, one ton of the catalysts are used for 3000 tons of coal. When used, the coal combustion composite nanometer catalyst can be diluted by water 5-10 times larger than the coal combustion composite nanometer catalyst according to the dry degree of the coal. The coal combustion composite nanometer catalyst has the advantages of improving sensible heat of the coal, saving the coal and protecting the environment.

Description

technical field [0001] The invention belongs to the field of coal combustion additives, in particular to a coal combustion composite nanometer catalyst. Background technique [0002] Fuel consumption is related to major issues of human survival such as energy resources, environment, and climate. Therefore, saving energy and protecting the environment are common issues facing mankind. Countries around the world have invested a lot of manpower and material resources to carry out theories and experiments on energy conservation and emission reduction. Research. At present, there are two theories about the mechanism of coal catalytic combustion, namely, oxygen transfer theory and electron transfer theory. No matter which theory involves the reaction active centers formed by catalysts or their decomposition products, the reaction activity increases, and the combustion must be accelerated and complete. This requires increasing the amount of catalyst and increasing the surface are...
