Abstract
The invention discloses a denitrating catalyst which comprises the following components in percentage by weight: 65-75% of calcium chloride, 10-18% of ammonium bicarbonate, 9-12% of urea and 5-9% of ammonium titanate. The denitrating catalyst disclosed by the invention is added into coal to combust, and the denitrating rate is maximally 40.5%.
Description
Technical field
The present invention relates to coal-fired field, relate in particular to a kind of denitrating catalyst.
Background technology
Nitrogen oxide (NO
x) be a kind of atmosphere pollution with very big harm, all can cause certain injury to the existence of health and animals and plants, as formed acid rain, photochemical fog etc., in environmental consciousness with require more and more stronger today, how to remove the discharge of nitrogen oxide, become more and more urgent problem.
Power plant can give off a large amount of nitrogen oxide in the process of coal combustion, although tradition can be removed nitrogen oxide to a certain extent for the catalyst of removing nitrogen oxide, but, still have that catalysis intensity is low, catalytic efficiency is low, catalyst amount is large, the high in cost of production shortcoming.
Summary of the invention
The purpose of this invention is to provide the denitrating catalyst that a kind of catalytic efficiency is high, catalyst amount is little and cost is low, this denitrating catalyst adds in coal and burns, and the denitration rate reaches as high as 40.5%.
In order to solve the problems of the technologies described above, the technical solution used in the present invention, a kind of denitrating catalyst comprises the component of following mass percent:
Calcium chloride 65-75%;
Carbon ammonium 10-18%;
Urea 9-12%;
