Description
Technical field
The present invention relates to a kind of useless copper-loaded methods for preparing adsorbent of mercury catalyst of outfield intensifying, belong to ultrasonic applications technology
Field.
Background technique
A large amount of presence of dead catalyst have resulted in serious problem of environmental pollution.Therefore, dead catalyst how is handled to have become
For a great problem in the world.On the one hand mercury is the pollutant of environmentally friendly mechanism most strict control, on the other hand in Chinese resource
It is exhausted.Be once the fifth-largest Chan Gong state of the world China nowadays also mercury-free can adopt already, annual production only 200 tons or so it is much full
The foot not consumption of annual 22000000 tons of polyvinyl chloride (PVC) production capacity, and mercury valence rises again and again, have been approached at present 500,000 yuan/
Ton.As the carrier of mercury catalyst, the production of each ton of qualified active carbon about consumes 10 tons or so of fat coal, and active carbon is current
Price has also pressed on towards 10,000 yuan/ton, therefore, the angle either from environmental protection, or consider from the rare precious degree of raw material,
The Induction refining produced and used should not all be re-used as waste to handle, and should be used as a kind of precious resources.
The dispatch of on 06 04th, 2010 Ministry of Industry and Information is " about printing and distributing generated by polyvinyl chloride by calcium carbide industry mercury pollution integrated control scheme
Notice " (Ministry of Industry and Information save [2010] No. 261), it is desirable that accelerate the R&D work without mercury catalyst, however even to this day, not yet look for
To effective mercury substitute, useless mercury catalyst is also handled without preferable method, thus finds the useless mercury of a synthetical recovery as early as possible
The method of catalyst be very it is necessary to.
There are two types of the useless mercuric chloride catalysts of method recycling inactivation at present: the first is to inactivate mercuric chleride catalyst as original
Material recycles mercury with pyrometallurgy；Second method is with mercuric chleride catalyst for inactivation raw material, chemical activation regeneration of deactivated chlorination
Mercury catalyst.Both methods has a great technological progress, but due in dead catalyst mercury content it is low, mercury cost recovery is too
It is high.Patent publication No. CN104138767A discloses the new method of regenerated mercuric chloride catalyst after a kind of activation of three-level, i.e., first will
Useless mercuric chloride catalyst is put into carries out low-temperature carbonization at 100~200 DEG C in regeneration activating furnace；Then add into activating and regenerating furnace
Enter carbon dioxide and vapor carries out steam activation；Activating solvent finally is carried out to remove to useless mercuric chloride catalyst using dilute hydrochloric acid
Trace impurity.The technology can make useless mercuric chloride catalyst obtain effective recycling and reusing, however, to ensure that useless mercury chloride touching
The regeneration efficiency of matchmaker still needs to before activation sieve useless mercuric chloride catalyst to remove incomplete Induction refining fine crushing and go forward side by side
Row respective handling, furthermore in activation process the problem of volatilization heated there is also mercury chloride.Patent publication No. CN103803638A
The new method for proposing a kind of " acidification-ultrasonic synergistic desorption " carrys out regenerated mercuric chloride catalyst, i.e., first by useless mercuric chloride catalyst
It is stirred thermosol pretreatment；PH to 1~3 is adjusted again, at 70~95 DEG C, is filtered after ultrasonication, and useless mercury chloride is made
The impurity such as mercury chloride and phosphorus in catalyst are separated with active carbon；The active carbon obtained after filtering can weigh after washing and screening
It is used newly in preparing new catalyst；Mercury ion can be made to be changed into mercury oxide precipitating after obtained filtrate is neutralized, can be obtained after filtering
Mercury oxide filter cake；Mercuric chloride solution can be obtained with dissolving with hydrochloric acid mercury oxide filter cake again, can be used for preparing new mercuric chloride catalyst.It should
Method there are complex disposal process, reagent consumption is larger the problems such as.
Accordingly, it is badly in need of researching and developing a kind of small investment, energy-saving and environment-friendly method realizes the resource of dead catalyst
Change processing.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of useless copper-loaded system of mercury catalyst of outfield intensifying
