Description
Technical field
The present invention relates to a kind of sulphur, arsenic, phosphorus cleanser and preparation method thereof.
Background technology
The impurity such as sulphur, arsenic, phosphorus are widely present in the raw materials such as natural gas, synthesis gas, coal gas, lightweight liquid state hydro carbons,
The presence of these impurity can cause many catalyst poisonings to inactivate, and greatly shorten catalyst life, even result in catalytic reaction without
Method is normally carried out；Can be as production be into being advanced into the composite of downstream, so as to bring a system in addition, not removing clean impurity
The problem of Environmental Health of row etc..Therefore, the impurity such as sulphur, arsenic, phosphorus are removed for protecting downstream unit high-efficiency high-accuracy
Major catalyst and the quality that improves downstream product at the same time have very important meaning.
Under normal circumstances, the sulphur-containing substance present in the raw material of industry is mainly H2S and COS, for these sulphur-containing substances
Deep removal effect most preferably Zinc oxide desulfurizer.Zinc oxide desulfurization with its desulfurization precision is high, easy to use, safe can
Lean on, sulfur capacity is high, plays " checking on " and " protection " acts on and occupy very important status, it be widely applied to synthesize ammonia,
The industries such as hydrogen manufacturing, coal chemical industry, petroleum refinement, beverage production, to remove natural gas, petroleum distillate, casing-head gas, refinery gas, synthesis
Hydrogen sulfide and some organic sulfurs in the raw materials such as gas, carbon dioxide.Sulphur in unstripped gas can be removed to by zinc sulphide desulfurization
0.055mg/kg.CuO is added in normal temp zinc oxide desulfuriging agent to improve its desulphurizing ability.It is de- that Zinc oxide desulfurizer is generally used for essence
Sulphur process, it can also absorb general organosulfur compound.Arsenic impurities in the raw material of industry, usually with AsH3Form exists, work
The Hydrodearsenic Catalyst used in industry is substantially divided into copper system, four class of lead system, manganese systems and nickel system, wherein relatively conventional with copper system.Copper system takes off
Arsenical arsenic holds height, can be carried out under room temperature, normal pressure and higher space velocity.Copper system Hydrodearsenic Catalyst is divided into metallic copper, CuO-Al again2O3、
CuO-ZnO-Al2O3Deng.When using CuO as active component, AsH3By Cu2+It is reduced at a low price or metallic state, arsenic is combined or swum with copper
From into element state.The development trend of desulfurizing agent and Hydrodearsenic Catalyst be to low bulk density, low temperature in use, high intensity and high sulfur capacity and
The direction that arsenic holds is developed.
Patent CN101591554A discloses a kind of normal temperature composite desulfurating and dearsenic agent and preparation method thereof, the desulfurating and dearsenic agent
It is made of carrier and active component, active component is lead oxide, magnetic iron oxide and cupric oxide, and carrier is γ-Al2O3, the desulfurization
Hydrodearsenic Catalyst needs, when 350~650 DEG C of activation 4~8 are small, to can be seen that the oxide desulfurization from its composition and preparation method and take off
Arsenical heap density is high, and preparation process is complicated, and commercial Application cost is higher.
Patent CN102049236A discloses a kind of copper zinc ambient temperature desulfuration agent and preparation method thereof, which is by alkali formula
Zinc carbonate, basic copper carbonate and binding agent composition, the preparation of the desulfurization sulfur agent is by commercially available basic zinc carbonate, basic carbonate
Copper, binding agent and water are mediated, are molded, being obtained after drying, which is obtained by physical mixed, thus zinc-copper therein
Active component can not play synergistic effect, so as to cause its Sulfur capacity relatively low.
Patent CN201410575030.5 discloses a kind of room temperature desulfurating and dearsenic agent and preparation method thereof, the desulfurating and dearsenic agent
It is made of aurichalcite, cupric oxide, zinc oxide and rare earth metal.The addition of rare earth metal improves the electric charge around Zn, Cu
Distribution, is conducive to the raising of its detergent power.
Patent CN201410314482.8 discloses a kind of sulphur arsenic adsorbent and preparation method thereof, which is by green
Copper zinc ore, cupric oxide, zinc oxide, iron oxide, manganese oxide composition.The addition of iron oxide, manganese oxide improves the Sulfur capacity of adsorbent
Hold with arsenic.
Although such scheme makes moderate progress and improves to the adsorption capacity of adsorbent.But, however it remains cleanser heap is close
The problem of degree is high, and adsorption capacity is low, it is especially low to the adsorption capacity of phosphorus.
The content of the invention
The technical problems to be solved by the invention are the problem of cleanser heap density are high, and adsorption capacity is low in the prior art,
A kind of new sulphur, arsenic, phosphorus cleanser and preparation method thereof are provided.The sulphur, arsenic, phosphorus cleanser contain aurichalcite and CuO-ZnO
Class solid solution, while nickel oxide is introduced, boehmite is added in precipitation process, improves the detergent power of cleanser, is had
There is the advantages of heap density is low, and adsorption capacity is high.
