Deep removal effect most preferably Zinc oxide desulfurizer.Zinc oxide desulfurization with its desulfurization precision it is high, easy to use, it is safe can
By, sulfur capacity it is high, play " checking on " and " protection " effect and occupy very important status, it be widely applied to synthesis 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.Sulfur in unstripped gas can be removed to by zinc sulfide desulfurization
0.055mg/kg.Add CuO in normal temp zinc oxide desulfuriging agent to improve its desulphurizing ability.Zinc oxide desulfurizer is generally used for loss of essence
Sulfur process, it can also absorb general organosulfur compound.Arsenic impurities in the raw material of industry, generally with AsH3Form is present, work
The Hydrodearsenic Catalyst used in industry is substantially divided into copper system, lead system, four class of manganese systems and nickel system, wherein relatively conventional with copper system.Copper system takes off
Arsenical arsenic holds height, can carry 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 with CuO as active component, AsH3By Cu2+Low price or metallic state are reduced to, arsenic is combined with copper or swum
From into element state.The development trend of desulfurizing agent and Hydrodearsenic Catalyst be to low bulk density, low use temperature, high intensity and high sulfur capacity and
The direction that arsenic holds is developed.
Patent CN101591554A discloses a kind of room temperature composite sulfur arsenic cleanser and preparation method thereof, the sulfur arsenic cleanser
It is made up of carrier and active component, active component is lead oxide, magnetic iron oxide and copper oxide, and carrier is γ-Al2O3, the sulfur arsenic
Cleanser needs to activate 4 ~ 8 hours at 350 ~ 650 DEG C, can be seen that the oxide sulfur arsenic from its composition and preparation method and purifies
Agent heap density is high, and preparation process is complicated, and commercial Application is relatively costly.
Patent CN102049236A discloses a kind of copper zinc ambient temperature desulfuration agent and preparation method thereof, and the desulfurizing agent 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 carry out mediating, molding, obtain after drying, and the desulfurizing agent is obtained by physical mixed, thus zinc-copper therein
Active component cannot play synergism, so as to cause its Sulfur capacity relatively low.
The content of the invention
The technical problem to be solved is that cleanser heap density is high in prior art, and utilization rate is low, commercial Application
A kind of relatively costly problem, there is provided new cleanser.The cleanser is for natural gas, synthesis gas, lightweight liquid state hydro carbons
Deng purification in when, low with heap density, utilization rate is high, commercial Application low cost advantage.
To solve above-mentioned technical problem, the technical solution used in the present invention is as follows：A kind of cleanser, with percentage by weight
Meter, including following components：A) 20 ~ 95% aurichalcite；B) 5 ~ 80% binding agent.
In above-mentioned technical proposal, in terms of cleanser percentage by weight, the preferred scope of aurichalcite is 35 ~ 65%；To purify
Agent percentage by weight meter, the preferred scope of binding agent is 15 ~ 35%；The binding agent is aluminium oxide, silicon oxide, alumina cement, fibre
At least one in dimension element, Kaolin, attapulgite, aluminosilicate cement, preferred aluminium oxide.
In above-mentioned technical proposal, it is preferable that the heap density of cleanser is less than 0.9kg/m3；
In above-mentioned technical proposal, it is preferable that the side pressure strength of cleanser is more than 70N/ grains.
In above-mentioned technical proposal, it is preferable that in terms of cleanser percentage by weight, cleanser is also comprising 7～23% ZnO and 8
~ 22 CuO.
In above-mentioned technical proposal, the preparation method of the cleanser is comprised the following steps successively：
(1) by copper nitrate, zinc nitrate, the water-soluble inorganic salt of aluminum nitrate and hydromassage, your ratio is counted：Cu/Zn is 0.1 ~ 2,；
