Description
Technical field
The present invention relates to a kind of renovation process of decaying catalyst, relate in particular to the renovation process behind a kind of low temperature hydrolytic catalyst of carbonyl sulfur inactivation.
Background technology
COS is the principal mode that organic sulfur exists in the industrial gasses, and the COS of trace is easy to cause the catalyst poisoning inactivation in the industrial production, and the equipment of industrial product is had corrosiveness.In addition, the not treated COS that is discharged in the atmosphere can form SO
2, promote photochemical reaction, and finally be converted into sulfate aerosol, bring serious environmental problem.Recently to the removal research of COS many be Hydrolyze method, under the effect of hydrolyst, utilize the steam in tail gas or the unstripped gas that COS is changed into more tractable inorganic sulfur hydrogen sulfide (H
2S), again hydrogen sulfide is removed by other approach.
CN1069673A discloses a kind of with γ-Al
2O
3Be carrier, with K
2CO
3COS hydrolyst for active component.This catalyst has hydrolysis preferably to the COS sulfides, simultaneously to H
2S also has good absorption function.But these hydrolysts are after operation a period of time, and activity obviously descends, but active component content is still very high in the catalyst of inactivation, and mechanical strength changes less, thereby is necessary it is regenerated, thereby prolongs its service life, economizes on the use of funds, and increases the benefit.
Hydrotalcite (Layered Double Hydroxides, LDHs) be a kind of class natural clay material with stratiform microcellular structure, have very big specific area, interlayer has tradable anion, is two hydroxy metal composite oxides that a class has the stratiform microcellular structure.LDHs is comparatively stable below 400 ℃, at high temperature slough intermediary water, anion and form the composite oxides of various metals or special hydroxide, this based composite oxide has higher specific surface area and strong basicity, can be used as catalyst or carrier through after the high-temperature roasting, mainly as various base catalysts and oxidation-reduction catalyst and carrier.Alkalescence and oxidation-reduction quality by means of this based composite oxide also are used to the development environment catalyst.
Dennis E.Sparks etc. are at Applied Catalysis B:Environmental, 2008, (82): disclose among the 58-66 with coprecipitation and prepared a series of houghites, and having studied the absorption property of calcined oxide to COS, the result shows that the oxide of deriving of houghite has suction-operated preferably to COS.
According to the literature, the COS hydrolysis is a base catalyzed reactions, and the composite oxides after the houghite high-temperature roasting have higher specific surface area, decentralization and strong basicity, but be applied to renovation process behind the COS hydrolytic inactivation about the composite oxides of deriving of houghite, have not yet to see practical and effective report.
Summary of the invention
Use not exclusively for overcoming catalyst, to problems such as the COS suction-operated are not obvious, the object of the present invention is to provide the renovation process behind a kind of hydrolytic catalyst of carbonyl sulfur inactivation, can regenerate after making the hydrolytic catalyst of carbonyl sulfur inactivation, prolong its service life, economize on resources, realize by following technical proposal.
