Description
Technical field
The present invention relates to a kind of method that mullite is prepared by FCC dead catalyst.
Background technology
At present, the annual working ability of China's catalytic cracking (FCC) is more than 1.5 hundred million tons, annual spent catalyst number
Amount is more than 200,000 tons.FCC catalyst in use, because catalyst is made under catalyst activity by heavy metal pollution
Drop, causes the reaction selectivity of catalyst to be deteriorated, if it is to be unable to maintain that the work of poising agent only to run damage by nature and supplement new agent
Property and selectivity, it is therefore desirable to periodically draw off a part of poising agent to ensure the activity and selectivity water of catalyst in device
It is flat.This poising agent drawn off is referred to as FCC dead catalyst.FCC dead catalyst activity is low, and contains a certain amount of heavy metal, dirty
Metachromia is strong, and harmless treatment is difficult, and enterprise is generally disposed using the burying method of simple general solid waste.FCC in 2016
Dead catalyst has been included in new issue《National Hazard waste register》, according to the management requirement of National Hazard waste, the useless catalysis of FCC
The processes such as the generation of agent, storage, transport, disposal will will be greatly improved by the control of country, processing cost.
How to utilize the useful component in FCC dead catalyst, realization turns waste into wealth, reclaim the material that has use value and
Resource, which is only, solves the problems, such as the basic of FCC dead catalyst.FCC dead catalyst recyclings, it on the one hand can pass through appropriate recycling
Processing obtains additional economic benefit, reduces Petrochemical Enterprises and always runs spending；On the other hand the environment of FCC dead catalyst can also be avoided
Secondary pollution.
FCC dead catalyst has been included in new issue within 2016《National Hazard waste register》, according to National Hazard waste
Management requires, the process such as the generation of FCC dead catalyst, storage, transport, disposal is by will be greatly by the control of country, processing cost
Width improves.FCC dead catalyst activity is low, and contains a certain amount of heavy metal, and contaminative is strong, therefore, it is necessary to FCC dead catalyst
Carry out harmless treatment.
Poisonous and harmful element in FCC dead catalyst, predominantly heavy metal element, typically using landfill method, chemical method and
Burning method carries out harmless treatment to FCC dead catalyst.
Landfill be easier with common method, but hazardous waste landfill construction cost is high and takes certain soil money
Source, and resource can not be utilized effectively, therefore can gradually eliminate.
It is below the mark that chemical method can not only drop to the content of beary metal in dead catalyst state control, can also make money
Effectively reclaimed in source.But the problem of this method pollutes environment there is also the spent acid aqueous slkali in disposal process.Particularly press
According to《Hazardous waste judging standard general rule》Regulation, have toxicity (including Leaching, acute toxicity and other toxicity) and sense
Waste after the hazardous waste processing of one or more kinds of hazard properties such as metachromia still falls within hazardous waste.Therefore, through chemistry
FCC dead catalyst after method disposal is still hazardous waste, does not reach innoxious purpose.
The content of the invention
The technical problems to be solved by the invention are that FCC dead catalyst is difficult to handle, pollutes asking for environment in the prior art
A kind of topic, there is provided new method that mullite is prepared by FCC dead catalyst.This method has FCC dead catalyst disposable, not dirty
The advantages of contaminating environment.
To solve the above problems, the technical solution adopted by the present invention is as follows：It is a kind of that mullite is prepared by FCC dead catalyst
Method, in heat plasma reactor according, FCC dead catalyst 1-10min are disposed at 1200-1500 DEG C, obtain including not coming
The product of stone；Wherein, plasma is plasma arcs or plasma torch.
In above-mentioned technical proposal, it is preferable that the voltage of plasma reactor is in 20-60V, electric current 100-190A.
In above-mentioned technical proposal, it is preferable that the mass content of mullite is more than 85% in the product including mullite.
This patent proposes a kind of method that hot plasma disposal of resources FCC dead catalyst prepares mullite, directly
Using heat plasma technology, without adding any added material, the dead catalyst of pollution environment is not only disposed, is also obtained
Mullite with higher economic value.Compared with other mullites preparation technology, the reaction time is short, and energy consumption is low, and mullite
Quality be basically unchanged, achieve preferable technique effect.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Embodiment
Embodiment 1
40g spent FCC catalysts are tested, experiment condition：The mesh of catalyst particle size 100, heat plasma reactor according voltage 20V,
Electric current 100A, 1200 DEG C, reaction time 10min of reaction temperature, the mass content of products therefrom mullite is 89%.
Embodiment 2
40g spent FCC catalysts are tested, experiment condition：The mesh of catalyst particle size 100, heat plasma reactor according voltage 40V,
Electric current 150A, 1300 DEG C, reaction time 1min of reaction temperature, the mass content of products therefrom mullite is 91%.
Embodiment 3
40g spent FCC catalysts are tested, experiment condition：The mesh of catalyst particle size 100, heat plasma reactor according voltage 60V,
Electric current 190A, 1500 DEG C, reaction time 5min of reaction temperature, the mass content of products therefrom mullite is 90%.
Obviously, treated spent FCC catalyst can prepare harmless mullite, not only realize FCC dead catalyst
Harmless treatment, and prepare mullite there is higher economic value, there is obvious technical advantage.
