Technical field
The invention belongs to waste and old catalyst application technology as the second resource fields, produce acetic acid more particularly to a kind of carbide acetylene method
The method of generated waste and old catalyst resource utilization in the technical process of ethylene.
Background technique
Vinyl acetate (VAc) is in one of important basic organic chemical raw material of vinylon industry and the world today
One of maximum Organic Chemicals of yield.Vinyl acetate is copolymerized by self-polymerization or with other monomers, and poly- second can be generated
Enol (PVA), vinyl acetate-ethylene copolymerization emulsions (VAE) or copolymer resins (EVA), polyvinyl acetate (PVAc), acetic acid second
The very extensive vinylon fibre of the purposes such as alkene-vinyl chloride copolymer (EVC).
In recent years, since Downstream Market is vigorous, the production of China's vinyl acetate is fast-developing.2011, China's acetic acid second
The production capacity of alkene reaches 2303kt/a, is more than that the U.S. becomes maximum vinyl acetate production country in the world.The end of the year 2016, I
The production capacity of state's vinyl acetate has reached 6183kt/a, wherein the production technology using carbide acetylene method accounts for about aggregated capacity
52.32%.
Catalyst is the medium of vinyl acetate synthesis reaction, thus vital work is played on vinyl acetate production line
With.Catalyst used in the technical process of carbide acetylene method production vinyl acetate be using active carbon as carrier, and it is micro- at its
A kind of catalyst of zinc acetate is adsorbed on hole.It is counted according to normal production operation situation, every 1 ton of vinyl acetate of production needs
10 kilograms of active carbon, 5 kilograms of zinc acetate.Thus it is not difficult to extrapolate, in the industrial production of China's vinyl acetate in 2016, using electricity
The discharge amount of stone acetylene method production technology Induction refining is up to 3.235 ten thousand tons.Catalyst inactivation after in the form of solid waste a large amount of heaps
Product is both a kind of significant wastage to resource, while waste and old catalyst belongs to certain hazardous waste attribute around plant area
Industrial solid castoff, it is any to abandon or stack the ecological environment for also easily seriously polluting periphery, biggish ring is brought to locality
Packing pressure and risk.
Currently, the recycling of waste and old catalyst has caused the great attention of people, but to regenerate recovered carbon
Based on, the waste liquid direct emission sewage treatment plant processing containing substances such as zinc acetates that treated is not comprehensively utilized.China
Patent CN100525901C although disclose it is a kind of to produce the dead catalyst regeneration method generated during vinyl acetate, should
Method is in heating furnace by control heating rate and heating and thermal insulation time, and activated carbon supported oxygen is made in activating and regenerating processing
Change the photochemical catalyst of zinc.Although the inventive method simple process, the resource recycling that can be realized waste catalyst is utilized,
The disadvantage is that needing heating and thermal insulation using process and carrying out activating and regenerating using water vapour, not only energy consumption is higher, and can produce

Falling off for sour zinc is serious, is discharged with reaction solution (first circulation liquid), and with the reduction of temperature, the crystallization of inner wall of the pipe zinc acetate is caused
Blocking causes the passive situation of production.
5. although, if state modulator is improper in reaction, the temperature in catalyst bed, which is higher than 200 degree, is in reaction process
It is easy to generation, to cause bed hot-spot.Moreover, the reaction rate of each particle is different in catalyst reactor
, hot spot is formed on the gas fluidized poor position of reactor, hot(test)-spot temperature can exceed that the decomposition temperature of zinc acetate, add
Exist in a large amount of powder of initial reaction stage, local location can be made small coke button occur, with continuing for reaction, coke button meeting
It gradually grows up to be formed and accelerates bed catalyst inactivation.Reactor distributing plate catalyst coking is a great problem of vinylon industry.
6. commercially available general active carbon is unable to satisfy the technology of the fresh catalyst of configuration carbide acetylene method production vinyl acetate
It is required that and need using domestic coconut husk charcoal, bird olive core charcoal and import coconut husk charcoal isoreactivity charcoal, but the price of these active carbons is all
It is very high, generally at 27000 yuan or so, increase the whole production cost of carbide acetylene method production vinyl acetate technique.
