Description
Technical field
The invention belongs to desulfurizing agent preparation and application field, specially renewable metal composite oxide Hot gas cleanups
The regeneration method and Hot gas cleanup purification process Sulphur ressource recovery method of agent, it is specifically a kind of to take off high temperature
The sulphur in one cerium oxide of iron oxide, one zirconium oxide base adsorbent after sulphur regenerates recycling in a manner of elemental sulfur, and makes desulfurization
The desulphurizing activated method for being able to restore and desulfurizing agent desulfurization regeneration process is able to circulation progress of agent.
Background technique
China's " rich coal, lacks natural gas at few oil " special non-renewable energy storage and consumption structure, determine following considerably long
Period, coal are still that China is most abundant, most reliable, most cheap basic energy resource.Coal directly burns, and using process, there are energy
The deficiencies of utilization efficiency is low, environmental pollution is serious, equipment investment is big, complex operation is measured, and as national economy is persistently good for
Health, environmental-friendly benign development, coal clean Efficient Conversion and using just becoming most potential coal utilization technology indirectly.
In coal, for clean Efficient Conversion with using in technology, coal high-temperature gasification is one of its key technology indirectly.In coal High Temperature Gas
Sulfide moiety during change in coal is transferred in coal gas body, and generate gaseous sulfide will lead to follow-up equipment with
The poisoning of instrument burn into catalyst inactivation is discharged into atmosphere and pollutes the unfavorable result such as environment again.Therefore gas desulfurization and purification is in coal
For cleaning Efficient Conversion with using one of the key link that is very important in technology, wherein Hot gas cleanup purification can indirectly
Using gas latent heat and sensible heat, has many advantages, such as that desulfuration efficiency height, desulfurizing agent can be used with repetitive cycling, become advanced gas
Desulfurizing and purifying method.Hot gas cleanup purification techniques high temperature gas desulfurizer is its core, and Hot gas cleanup
Agent performance and desulfurization technical requirements are closely related.Desulfurizing agent for high-temp gas performance mainly has desulfurization Sulfur capacity, desulfurization precision, renewable
Property, mechanical endurance, structural stability etc..Currently, desulfurizing agent for high-temp gas usually has oxidation according to desulphurizing activated component type
Iron-based, Zinc oxide-base, manganese oxide base, oxidation decorations base, ferrous acid zinc-base, sour zinc-base of admiring, iron decorations oxide-base etc..Hot gas cleanup
It include two consecutive steps of desulfurization and regeneration in agent application process, wherein regeneration is to realize the recycling of desulfurizing agent for high-temp gas Sulphur ressource
With the essential link of recycling.Iron oxide based high-temperature coal gas desulfurizing agent is convenient with raw material sources, and manufacturing price is low,
It is higher to be saturated desulfurization Sulfur capacity, can regenerating easily the advantages that, but desulfuration efficiency, that is, desulfurization precision is not high, and fuel factor is big in regenerative process
Easy-sintering, the unstripped gas desulfurizing and purifying not high suitable for required precision, Chinese patent (CN101805641A) has been invented a kind of high
Temperature coal gas desulfurizing agent regeneration technology is related to a kind of coal gas of high temperature oxidation iron-base desulfurizer.Oxidation decorations base desulfurizer is a kind of new
The desulfurizing agent for high-temp gas of type regenerates regeneration product under atmosphere and there was only elemental sulfur, and regeneration product is single, is conducive to Sulphur ressource and recycles,
Oxidation decorations stability is good in desulfurization and regenerative process, and regenerative response heat release is few, and cerium is not easy volatilization loss or forms sulphur
Hydrochlorate, is known as second generation desulfurizing agent for high-temp gas, but it is low to aoxidize decorations based high-temperature coal gas desulfurizing agent desulfurization Sulfur capacity, and need compared with
High desulfurization and regeneration temperature.Desulfurizing agent for high-temp gas performance and regeneration product resource utilization and the close phase of regeneration atmosphere composition
Close, desulfurizing agent for high-temp gas regeneration atmosphere mainly include oxygen, vapor and sulfur dioxide atmosphere and oxygen-vapor and
Oxygen-sulfur dioxide atmosphere.Oxygen atmosphere regeneration product sulfur speciation is mainly sulfur dioxide gas, steam atmosphere regeneration product
Sulfur speciation is mainly hydrogen sulfide gas, and sulfur dioxide atmosphere regeneration product sulfur speciation is mainly elemental sulfur solid.
Summary of the invention
The regeneration method of gas desulfurizer of the present invention, it is therefore intended that in current Hot gas cleanup regeneration cycle process
It is primarily present regeneration product complexity, it is difficult to separate and recover recycling use, desulfurizer regeneration rate is not high, high temperature desulfurizing regenerative sulfur binding
The problems such as structural instability in agent active component cyclic process, regeneration temperature height easily leads to desulfurizing agent temperature runaway.According to sulfur dioxide
The desulphurizing activated component iron oxide of atmosphere high temperature desulfurizing agent is different with oxidation decorations, the regenerative response of generation be respectively the endothermic reaction with
The fuel factor difference of exothermic reaction sees below column chemical equation, and Lai Shixian desulfurizing agent for high-temp gas regenerative process mildly operates, and
Finally provide a kind of regeneration product it is single and can the recycling of high efficiency Sulphur ressource, regeneration efficiency it is high, desulfurizing agent knot in regenerative process
