Description

technical field [0001] The invention belongs to the technical field of coal processing, and in particular relates to a coal denitration agent. Background technique [0002] Coal provides heat energy to humans during combustion, but it also produces SO 2 , NO X Harmful substances such as smoke and dust have made China's air pollution very serious. SO from coal combustion in China 2 emissions accounted for 90% of the total emissions, the annual SO 2 The emissions are about 20 million tons; the NO produced by production and living activities in China X Up to 50 million tons, the NO produced by coal burning X Emissions account for 60-80% of total emissions; dust emissions from coal combustion in China account for about 70% of total emissions, with an annual emission of about 20 million tons. With the continuous development of the national economy, the consumption of coal will continue to increase, which will make SO 2 , NO X , smoke and other air pollution has become mo...
