Description
Technical field
The present invention relates to a kind of potassium basis soot combustion catalyst and preparation method thereof, belong to environmental catalysis technical field.
Background technology
Soot particulate is the important pollutant of a class of diesel emission.Carbon soot particles pollutant energy long-term suspension forms aerosol in atmosphere, reduce the visibility of air, not only affect sight line, visibility is reduced, simultaneously carbon smoke pollution thing also can stimulate lung, causes human body anoxia, slow poisoning, occur anaemia, nervous, feel sick, the various disease conditions such as headache, respiratory disease, pulmonary edema, skin disease and allergic disease, cause bronchitis and pneumonia, reduce people's respiratory system to the resistance infected; Also may make conjunctival congestion, shed tears, ophthalmodynia, have sore throat, pant, cough, even have difficulty in breathing.The more important thing is, these harmful substances are enough to carcinogenic! As low latitude mobile pollution source, carbon smoke pollution thing is floating apart from about 1.2 meters, ground, with the respiratory tract of people at same horizontal line, people is easy to the particle inspiration lung of emission by exhaust pipe, and contain a lot of carcinogen in the dissolved organic matter that carbon granule adsorbs (SOF) component as BaP etc., directly jeopardize health.In addition, black smoke with stink give direct offending detest sense.Therefore, the control of diesel emission carbon smoke pollution thing always is the emphasis of policies of various countries management and technical research, and the process of carbon smoke pollution thing more and more receives the concern of people.
Filtering the mode be combined with catalytic combustion is the mode the most effectively processing soot at present.Due to soot discharge time, first will adhere on the filter, therefore the catalytic oxidation of soot is the regeneration issues of exhaust gas from diesel vehicle filter in fact.The regeneration of filter, maximum problem is operation inconvenience, or expense is too high.If catalyst attachment on the filter, by effectively reducing the burning-point of soot, make it can burn under usual delivery temperature, just can realize not needing dismounting and continuous reproducible, not only easy to maintenance, simple to operate, and while raising the efficiency reduction energy consumption, can also secondary pollution be reduced.Thus develop the high activated catalyst of soot low-temperature burning, problem can be made perfectly to be solved, therefore the key of problem is just the catalyst finding a kind of like this function admirable.
Catalyst for the process of carbon smoke pollution thing comprises noble metal catalyst and non-precious metal catalyst etc., noble metal catalyst passes through active and stability is all higher, but its development of the price limit of its costliness, the non-precious metal catalyst developing a kind of superior performance is the focus paid close attention to of researcher both at home and abroad at present.Large quantity research shows, sylvite possesses good catalysis soot combustion activity, but sylvite very easily runs off in catalytic process, makes the stability of its catalysis be difficult to ensure.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, the invention provides a kind of potassium basis soot combustion catalyst and preparation method thereof.The nucleocapsid structure potassium basis soot combustion catalyst that the present invention prepares not only effectively can stop the loss of sylvite in catalytic process, the catalytic activity of catalyst can also be significantly improved, can while significantly reducing costs, improve the treatment effeciency of pollutant, the present invention is achieved through the following technical solutions.
