Description
Technical field
It is more particularly to a kind of to be used to be catalyzed urging for chlorinated organics burning the present invention relates to chlorine contained exhaust gas processing technology field
Agent and preparation method thereof.
Background technology
Volatile organic matter (VOCs) is that one kind has higher vapor pressure, is present in sky in vapour form at normal temperatures and pressures
A kind of volatile organic matter in gas, by the difference of its chemical constitution, main component is：Alkanes, organic chloride, freon
Series, organic ketone, amine, alcohol, ether and oil hydrocarbon compound etc..Wherein chloride volatile organic matter (CVOCs) obtains many researchs
The concern of person, it is larger mainly due to its harm of health to people, and also part CVOCs can also destroy atmospheric ozone layer, lead
Cause photochemical fog and air acidification etc..But these materials are due to there is the inertness of preferable dissolubility and reaction,
So that this kind of compound is widely used in chemical production.In addition, in recent years, the haze that constantly frequency increases shows
As, allow people more recognize environmental problem it is severe with it is critical.Therefore, the processing of organic exhaust gas turns into a necessity with administering
And the problem of urgent.At present, catalytic oxidation is because with initiation temperature is low, energy consumption is low and and almost non-secondary pollution etc. is excellent
Point, it is considered to be most efficient energy-saving and economically viable method, be increasingly subject to the concern of people.
Combustion method refers under the participation of active oxygen species and lower temperature conditions, can be incited somebody to action in suitable Jue agents
CVOCs deep oxidations are degraded to CO2、H2O and HCl method,
Its course of reaction is as follows：
Advantage compared to other treatment technologies , Onlyization combustion methods is mainly reflected in：Initiation temperature is low, and energy consumption is small；Remove
Rate is high, and secondary pollution is small；The scope of application is wider, selects suitable Jueization to carve, can almost handle all CVOCs.In Jueization
In combustion process, it is the key that efficient degradation is reacted to select suitable catalyst, is broadly divided into noble metal catalyst and your non-gold
The class of metal catalyst two.Noble metal Jue agents (such as loading ruthenium, palladium, platinum, gold) have high activity, generation HCl selectively high excellent
Point, but the shortcomings of expensive and catalyst is easily poisoned be present.In addition, non-Gui Jin Shu Only agent (such as molecular sieve, transition metal
Oxide and rare earth metal composite oxide etc.) change has higher reactivity, and has cheap, anti-poisoning etc. excellent
Point.
Patent CN103962134A discloses a kind of method that chlorinated aromatic hydrocarbons burning eliminates, and is with cerium oxide nano-rod, receives
Rice cube and nanometer regular octahedron be carrier-supported precious metal ruthenium as catalyst, and pass through dilute alkaline soln absorbing reaction tail
Gas.This method catalytic activity is high, and reaction non-secondary pollution thing produces, but catalyst cost is high, it is difficult to industrial applications.Patent
