Description
Technical field
The present invention relates to a kind of sulphur arsenic adsorbents and preparation method thereof.
Background technology
The impurity such as sulphur arsenic are widely present in the raw materials such as natural gas, synthesis gas, coal gas, lightweight liquid state hydro carbons, these
The presence of impurity can cause many catalyst poisonings to inactivate, and greatly shorten catalyst life, and even resulting in catalysis reaction can not be just
Often carry out；It can be as production be into being advanced into the composite of downstream, so as to bring a system in addition, not removing clean sulphur arsenic impurities
The problem of Environmental Health of row etc..Therefore, master of the impurity such as sulphur arsenic for protection downstream unit is removed to high-efficiency high-accuracy
The catalyst and quality for improving downstream product simultaneously has 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 certain 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 substantially can be 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 can be 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 copper oxide, and carrier is γ-Al2O3, the desulfurization
Hydrodearsenic Catalyst needs to activate 4~8 hours at 350~650 DEG C, can be seen that the oxide desulfurization from its composition and preparation method and takes 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 mediated, is molded, dry after obtain, which is obtained by physical mixed, thus zinc-copper therein
Active component can not play synergistic effect, relatively low so as to cause its Sulfur capacity.
