Description
Technical field
The invention belongs to flue gas wear-resistant catalyst technical field, and in particular to a kind of flue gas wear-resistant catalyst.
Background technology
Domestic coal-burning power plant's nitrogen oxides (NOx) emission reduction enters the key stage, and new demand is proposed to denitration technology.It is economical new
Under normality, domestic industry business electrical amount is remarkably decreased, and electric power outsourcing ratio etc. is improved in Energy restructuring, some areas in addition
Policy factor causes supply of electric power structural reform, middle Electricity Federation issue《2016 years, national power supply and demand situation analysis was observed and predicted in advance
Accuse》Middle prediction annual thermal power generating equipment in 2016 will further decrease to 4000 hours or so using hour, it means that coal burning machine
Group underload, variable load operation operating mode will further increase.
Under low load condition, flue-gas temperature is relatively low, and traditional catalyst activity is not high, and removal of nitrogen oxide effect is limited；
And now SO in flue gas3、H2O、NH3Catalyst surface is adhered to Deng the easy liquid sulfuric acid hydrogen ammonium (ABS) that formed, causes to be catalyzed
Agent Adsorption is capped, and denitration effect is deteriorated.
The content of the invention
A kind of flue gas wear-resistant catalyst that the present invention provides for prior art weak point.
