Description
Technical field
The present invention relates to gas purification technical fields, and in particular to the side of hydrogen sulfide and Recovered sulphur is removed from coal gas
Method.Specifically application it is a kind of based on expanded graphite be carrier supported metal oxide desulfurizing agent absorb hydrogen sulfide and by its
The method for being converted into sulphur.
Background technique
Coal Gasification Technology is to develop coal-based chemicals, Coal-based Liquid Fuel, natural gas from coal, IGCC integral coal gasification joint
The leading technology and key technology of the industries such as circulating generation, coal hydrogen manufacturing.Following coal high-efficiency clean conversion using will with it is large-scale,
Advanced Coal Gasification Technology is core, carries out Integration ofTechnology by direction of Poly-generation such as electricity, change, heat, this exists to Coal Gasification Technology
More stringent requirements are proposed for technical stability, environmental protection, energy consumption, equipment manufacturing, process optimization etc..
In addition to H in all kinds of synthetic raw gas produced using modern coal gas technology2, outside the available gas such as CO, also contain sulphur
Compound (H2S, COS), cyanide and CO2Equal impurity.The presence of these sulfur-containing compounds of coal gas not only pollutes the environment, but also
Corrosion harmfulness directly can be caused to downstream process and equipment, cause the poisoning and deactivation of catalyst in subsequent synthetic reaction process, directly
Connect the yield and quality for influencing final products, it is therefore necessary to be removed and be recycled.The removing and recycling of sulphur in coal gas, not only
The quality of synthesis gas can be improved, but also important sulphur resource can be recycled.The method of coal gas desulfurization has wet process and dry method
Two major classes.
Wet desulphurization can handle the very high coal gas of sulfur content, and wet desulphurization can be divided by the absorption of solution and regeneration properties
Chemical absorption method, Physical Absorption method and physicochemical adsorption method etc..Desulfurizing agent is easy for the liquid material of conveying, not only can be with
Regeneration, and valuable element sulphur can be recycled, it is the circulatory system of a continuous desulfurization, need to only supplements during operation
A small amount of material, to compensate for losses.But wet desulfurizing process is used, process flow is longer, and equipment is more, mainly includes filler
The equipment such as tower, column plate tower, valve tower, flash vessel, stripper, heating and cooling.In order to recycle valuable sulphur resource, it is also necessary to
Meet Sulfur Recovery Unit workshop section.Therefore, using wet desulphurization and to recycle the processing disadvantages of Sulphur ressource be that equipment is more, technique compared with
It is long.
Dry desulfurization removes again after sulfide is directly removed or converted using desulfuration adsorbent and (or) catalyst
Process.The characteristics of dry desulfurization is desulfurization precision height, and investment, operating cost are low, almost without power consumption, is suitble to inlet concentration
Low and few treating capacity desulfurization requirement.Subsequent refinement of the dry desulfurization generally as large-scale gas cleaning device, Ji Huke
Thoroughly to remove the sulfide in coal gas.Desulfurization by dry method has different classification methods according to different standards.With desulfurization
Agent is standard, can be divided into Fe-series desulfurizing agent, aluminium fimily desulfurizing agent, zinc fimily desulfurizing agent, activated carbon desulphurization agent and molecular sieve desulfurizer
Deng；Using chemical principle as standard, catalytic absorption method, absorption method, gas-solid reaction method and catalyzed hydrolytic methods etc. can be divided into.With
Wet desulphurization is compared, and the absorption of dry process desulfurization, desorption process are that interval carries out, and dry desulfurization is maximum the disadvantage is that equipment
Huge, desulfurizer regeneration is difficult.
Expanded graphite refers to the acidified processing of natural flake graphite, forms compound between graphite layers, be washed to it is neutral,
It is quickly heated after drying, is allowed to be expanded into vermiform substance (also known as graphite worm).Expanded graphite is as a kind of loose porous
Carbon materials, surface and internal pore structure are very flourishing, and specific surface area is up to 50~200m2/ g is a kind of excellent suction
Enclosure material.Expanded graphite has the characteristics that low-density, lightweight, and high temperature resistant, corrosion-resistant, resistance to oxidation also have high chemistry
Stability and nontoxic feature are a kind of environmental-friendly substances.Just using expanded graphite as a kind of research of adsorbent material
Starting, in recent years, part scientific worker just notices the unique pore structure of expanded graphite and its characterization of adsorption, begins one's study swollen
Application of the swollen graphite as adsorbent in terms of environmental protection.
