Abstract
The present invention discloses a hydrolyst for COS and CS2 and an application thereof, which belongs to the technical field of desulfurizing agents and application field. The hydrolyst for COS and CS2 of the present invention is prepared in such a manner that ammonium salts are loaded on gamma-Al2O3; the hydrolyst for COS and CS2 solves the problem that organic sulfur can not be eliminated in high precision by the existing desulfurizing agent; the hydrolyst for COS and CS2 has the advantage of high conversion rate for eliminating the organic sulfur.
Description
Technical field
The present invention relates to a kind of desulfurizing agent and application thereof, more particularly, the present invention relates to a kind of COS and CS
2Hydrolyst and application thereof.
Background technology
As everyone knows, desulfurization is the important process link of raw material gas purifying in many Chemical Manufacture.Numerous chemical enterprises are adjusted raw material route one after another to continually develop new product, meet market competition and pursue best economic benefit.Yet in many raw materials, exist various sulphur compositions, for example inorganic sulfur such as hydrogen sulfide, organic sulfur such as cos, carbon disulfide.Therefore, require sulfur removal technology to have and keep high desulfuration efficiency, gas purification degree, and applied range, easy to use, cost is low, characteristics such as safe and harmless.
With unstripped gas process wet desulphurization earlier, unstripped gas still has the H of trace through after the wet desulphurization generally speaking
2S and organic sulfur exist, and wherein COS is topmost organic sulfur composition, contains a spot of CS sometimes
2Organic sulfur with forms such as mercaptan, thioether, thiophene.Studies have shown that these Determination of Trace Sulfur are to cause catalyst active center such as first sulphur, methanation, ammonia synthesis to poison and the main cause of inactivation.Because dry desulfurization is to H
2S and organic sulfur all have higher degree of purification, so people have developed various types of desulphurization catalysts.But until now, existing desulfurizing agent can not remove the high organic sulfur of content.
Summary of the invention
The present invention can not remove the high organic sulfur problem of content for what existing desulfurizing agent existed, has proposed COS of the present invention and CS
2Hydrolyst and application thereof.
Concrete technical scheme of the present invention is as follows:
COS of the present invention and CS
2Hydrolyst is with γ-Al
2O
3Be carrier, ammonium salt is the load component, and the ammonium salt weight percent content is 5～10%, and surplus is a carrier.
The preferred ammonium nitrate of described ammonia salt, ammonium chloride, ammonium sulfate, carbonic hydroammonium.
Described hydrolyst is that white is spherical, and diameter is 4～5mm, and specific area is 200～300m
2/ g, bulk density are 0.6～0.75kg/L, and compressive resistance is 80～200N/cm

COS of the present invention and CS
2There is no particular limitation for the preparation method of hydrolyst, ammonium salt can be immersed in and obtain catalyst of the present invention on the carrier.
COS of the present invention and CS
2The application of hydrolyst, the serviceability temperature that it is characterized in that it is 50～120 ℃, and pressure is 0.1～8MPa, and the gaseous phase volume air speed is 1000～2000h
-1
Alumina base plays important effect in the catalyst of the present invention, because the basic center that aluminium oxide shows can play catalytic action, strengthened hydrolysis rate, increasing ammonium makes the acid site on surface poison the posthydrolysis increased activity, and after acid poisons basic center, hydrolysing activity descends, so these illustrate that all basic center is the activated centre of hydrolysis, thereby has reached beneficial effect of the present invention.To removing of organic sulfur, conversion ratio can reach more than 95%.For the extra high unstripped gas of content, can the secondary hydrolysis transform.
The specific embodiment
Adopt the mode of specific embodiment to further specify the present invention below, but the present invention is not limited to these embodiment.
Embodiment 1
Adopt equi-volume impregnating that 8kg ammonium nitrate is immersed in γ-Al
2O
3On, make hydrolyst of the present invention.
Embodiment 2
Serviceability temperature is 50～120 ℃, and pressure is 0.1～8MPa, and the gaseous phase volume air speed is 1000～2000h
-1
The catalyst that 10 liters of embodiment 1 are obtained be seated in desulfurizing agent bed in, feed and contain 100 * 10
-6The nitrogen of cos, air speed is 1000h
-1, temperature is 60 ℃, and pressure is normal pressure, and the sulfur content of desulfurizing agent bed outlet is 1 * 10 after measured
