Abstract
The invention discloses an activated carbon desulfurizing agent and its application in the field of desulfurizing agent and its application which comprises activated carbon, alkali metal compound and alkaline earth compound. It resolves the problem that current technology can not desulfurize below 0.03x10.-6.
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 activated carbon desulphurization agent 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 exist desulfurization precision low, sulphur can not be taken off to 0.03 * 10
-6Following problem.
Summary of the invention
The present invention for solve in the prior art desulfurization precision low, sulphur can not be taken off to 0.03 * 10
-6Following problem is studied a kind of activated carbon desulphurization agent of smart desulfurization.
Technical scheme of the present invention is:
Activated carbon desulphurization agent of the present invention is made up of the component of following weight percentage: active carbon 80～95%, alkali metal compound 2～10%, alkaline earth metal compound 3～10%.
The preferred NaOH of described alkali metal compound, potassium hydroxide, sodium chloride, sodium nitrate, potassium chloride, potassium nitrate; The preferred magnesium hydroxide of described alkaline earth metal compound, calcium hydroxide, magnesium chloride, calcium chloride, magnesium nitrate, calcium nitrate.
Described desulfurizing agent is the black strip, and diameter is 4 * 2.5～10mm, and specific area is 600～800m
2/ g, bulk density are 0.6～0.62kg/L, and compressive resistance is 50～80N/cm.
There is no particular limitation for the preparation method of desulfurizing agent of the present invention, alkali metal compound and alkaline earth metal compound can be immersed in and obtain desulfurizing agent of the present invention on the active carbon.
All raw materials of the present invention are the commercially available prod.
Activated carbon desulphurization agent of the present invention is applied to various smart desulfurization industrial process, and serviceability temperature is 25～45 ℃, and the gaseous phase volume air speed is 500～1000h
-1, pressure is 0.1～8MPa.
When the active carbon that inner surface is very big contacted with admixture of gas, the sulfide in the gas was absorbed into activated carbon particles inside, and its concentration is reduced.
Add alkali metal and alkali-earth metal modified active carbon in the active carbon simultaneously, can the effect of organic sulfide removal be significantly improved.
When the gas that contains hydrogen sulfide and oxygen passed through active carbon, hydrogen sulfide at first was adsorbed, and the hydrogen sulfide and the reaction of the oxygen in the gas that are adsorbed on the activated carbon surface generate sulphur and water, and the sulphur of generation and water are also by charcoal absorption.When containing aerobic and water in the gas, water and oxygen are adsorbed successively.On the pore surface of active carbon, form skim alkalescence moisture film simultaneously, then produce the series of chemical of similar liquid catalytic desulfurizing process.Therefore desulfurizing agent of the present invention can take off hydrogen sulfide in the unstripped gas and cos to 0.03 * 10
-6Below.
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
90kg active carbon, 5kg NaOH and 5kg magnesium nitrate are mixed, obtain desulfurizing agent of the present invention with the banded extruder extrusion.
Embodiment 2
The catalyst that 10 liters of embodiment 1 are obtained be seated in desulfurizing agent bed in, feed and contain 100 * 10
-6Hydrogen sulfide and 50 * 10
-6The nitrogen of cos, air speed is 1000h
-1, temperature is 30 ℃, and pressure is normal pressure, and the sulfur content of desulfurizing agent bed outlet is 0.02 * 10 after measured
