Abstract
Cu acetylide-contg. catalyst is passed continuous or in batches, in suspended form into a regeneration reactor under a N or air atmos. at least 200-300 deg C, sufficient catalyst being supplied so that the reactor temp. does not exceed a max. temp. between 300 and 600 deg C. C-contg. material is burnt off by addn. of air with addn. of N, Ar, flue gas or steam, as required. The catalyst is discharged from the reactor in the regenerated state.
Description
The present invention relates to contain acetylide, especially contain the renovation process of the catalyst of acetylene copper.
To use the catalyst that contains acetylene copper such as in butynediols synthetic.These catalyst that contain acetylide must often be regenerated.Except that acetylide of having mentioned or acetylene copper, such catalyst also contains different polymer.The regeneration of such catalyst divides two steps to carry out in principle.During regeneration, earlier acetylide is decomposed in the first step, to form carbon compound.Then, in second step by air or contain the inert gas dopant such as the air of nitrogen or argon gas is removed organic matter through regenerated catalyst.In the hot method of reproduction of catalyst of routine, can produce huge adiabatic temperature rise because of acetylide decomposes.The decomposition of acetylide will be experienced the chain reaction of strong heat release, and this reacts Once you begin, and is promptly uncontrollable, produces huge potential danger thereby exist.Because catalyst that usually all will be to be regenerated is contained in the cold regenerating furnace or reactor, and then it is heated gradually, whole fill just reacts suddenly in the reactor, produces the above-mentioned acetylide decomposition reaction that produces do not expected thus, and this reaction is through implying danger.(only as BIOS report No.367, London, 1945).
Purpose of the present invention promptly is to overcome the defective of known method.
Above-mentioned purpose of the present invention realizes by following manner, catalyst is suspended in the regeneration reactor, this reactor is under nitrogen or the air atmosphere or under the steam, at least keep 200～300 ℃ temperature, being added to catalyst in the regeneration reactor can not make temperature of reactor surpass maximum temperature between 300～600 ℃ at most, come the carbonaceous material of calcination generation by the air or the steam that add air injection or contain, will from regeneration reactor, take out through the catalyst of regeneration then just like inert gas dopants such as nitrogen, argon gas, flue gases.
In the method for the invention, the catalyst that will contain acetylide infeeds in the regeneration reactor with suspended form.For this reason, earlier catalyst is for example suspended in water.Opposite with method of the prior art, catalyst is not imported in the cold regeneration reactor, be under blanket of nitrogen or argon atmospher or the steam but import, temperature is at least in 200～300 ℃ regeneration reactor.In view of the above, prevailing higher temperature makes catalyst rapid draing in regeneration reactor, and makes acetylide begin to decompose, and the temperature in the regeneration reactor raises at this point.Therefore only it is noted that according to the present invention that the catalytic amount that imports in the regeneration reactor will make the temperature of regeneration reactor be no more than the maximum temperature of defined just, also the decomposition thermal conductance of acetylide can be loose.The maximum temperature that can not surpass in the regeneration reactor depends on each catalyst (material).Regeneration reactor can design according to the structure of temperature and pressure that produces in the catalyst decomposes or regeneration reactor, then its withstand voltage, that temperature resistant capability is determined catalyst addition.After in the above described manner regeneration reactor being added completely, filler decomposes spontaneous acetylide and does not add any restriction, has decomposed fully up to acetylide.In addition, be equipped with in the regeneration reactor of catalyst and also contain hydrocarbon and polymer.In addition, during decomposing, acetylide also can form carbonaceous material.These carbonaceous materials in regeneration reactor are by air or contain the inert gas dopant such as the air or the steam of nitrogen, argon, flue gas come calcination, and after the calcination program finished, catalyst was reduced fully, then with it by taking out in the regeneration reactor.
The present invention further proposes, be included in the regeneration reactor carbonaceous material or during the loader program or after loader program is finished by calcination.
Be included in carbonaceous material in the regeneration reactor burned more useful during the loader program than burning after loader program is finished, the one, operating process is quick, and promptly the recovery time is short; The 2nd,, inert gas needn't be provided during loader program again, and second kind of this program of situation.And the measurement in this method is all relative less with the control technology expenditure.
No matter use any of above-mentioned two kinds of methods, the existing potential danger that contains in the catalyst of acetylide in regeneration all is reduced to minimum at present.This regeneration reactor that is used for regenerating needn't need the necessary requirement to pressure and temperature of conventional regeneration method again.
The present invention further proposes, and catalyst can be continuously or put into regeneration reactor in batches.
In above-mentioned two kinds of situations which be method of the present invention select, and depends primarily on the amount of catalyst to be regenerated.
The present invention further proposes again, and regeneration reactor can be rotary furnace, drum reactor or stirs cooking-pot type reactor (Ruhrkesselreaktor).
The advantage of the inventive method may be summarized as follows:
-renovation process of the present invention can simple and easyly be controlled aspect safe practice.
The structure of-reactor or stove is not really high to the requirement of pressure and temperature.
-because as mentioned above, simplified the reactor design and reduced requirement, so investment cost and operating cost are all very little to security.
