Description
Technical field
The present invention relates to the method that agricultural shell discarded object prepares activated carbon from activated sludge, belong to solid waste efficient resource
Change and utilize technical field and recyclable organism mass-energy field.
Background technology
Activated carbon as a kind of Functional carbon material, because with specific surface area is big, pore structure is flourishing, adsorption efficiency is high,
Good chemical stability and the various aspects for being widely used in industrial and agricultural production, such as sewage disposal, gas purification, gold
Extraction, solvent recovery etc..Prepare the raw material sources of activated carbon extremely to enrich, it is agriculture and forestry organic waste material to study at present more（Such as agriculture
Crop material, rice husk, timber, pomelo peel and various shucks etc.）.These agriculture and forestry organic waste materials are cheap and easy to get, and prepare biomass
The technique of charcoal is simple, therefore plays more and more important effect in activated carbon preparation.Active charcoal preparing process flow is general
Including two stages --- charing and activation, wherein charing is the preparatory stage of activation, activation is core rank prepared by activated carbon
Section.Activated carbon prepares affected by many factors（Such as impregnating ratio, carbonization temperature and time, gas flow, activation temperature and time
Deng）, different activation methods can also influence the pore-size distribution and specific surface area of activated carbon, so as to influence its absorption property.
Carbonization process prepared by activated carbon is that under conditions of high temperature or oxygen deprivation, carbonaceous material is pyrolyzed into porous
Carbonized material.The non-carbon elements such as hydrogen, oxygen in this process, in carbonaceous material can generate escaping gas effusion.Carbonized material
Because the scrambling of its own can form certain crack, these cracks further can form richer in follow-up activation process
Rich pore structure.Influenceing the factor of charred effect includes carbonization temperature, carbonization time and gas flow etc., wherein carbonization temperature
The influence of pore-size distribution and specific surface area to activated carbon is larger.Carbonization temperature is generally 300~1000 DEG C, with carbonization temperature
Rise, the phosphorus content of carbonized material gradually increases, and charred effect is good, and the performance of activated carbon is also better, but carbonized material yield by
Gradually reduce.So suitable carbonization temperature is necessary condition prepared by activated carbon.Activated carbon is main to the absorption property of pollutant
Depending on its pore structure and surface chemistry.Though carbonized material shape color is as activated carbon, because its specific surface area is small,
Absorption property is poor, can't be referred to as activated carbon, therefore, and the further activation process to carbonized material is very necessary.
Activation process is to utilize gas（Such as vapor, carbon dioxide）Or chemical reagent（Such as zinc chloride, potassium carbonate, hydrogen-oxygen
Change potassium, phosphoric acid etc.）Processing is processed further to carbonized material, the purpose is to change the internal structure of carbonized material, expands specific surface area
To strengthen absorption property.Mainly there are 3 kinds of activation methods at present：Physical activation method, chemical activation method.Physical activation method is with oxidation
Property gas（Such as carbon dioxide, vapor, air）Carbonized material is activated for activator.Carbonized material is made by activation process
The expansion of pores that original inaccessible hole is opened, opened, while createing new bore, forms more flourishing pore structure.Influence thing
The principal element of reason activation effect has feedstock property, activation temperature, soak time, activator species and gas flow etc..It is most normal
Activator is carbon dioxide and vapor.The technical process that physical activation method prepares activated carbon is simple, the activated carbon of preparation
Micropore is more flourishing and No clean, and environmental pollution is small.Chemical activation method is main method prepared by current activated carbon.The method be by
Chemical activating agent is added in raw material by a certain percentage, hybrid infusion for a period of time after, synchronous charing and activate.Conventional chemistry is living
Agent has zinc chloride, potassium carbonate, potassium hydroxide, phosphoric acid etc..Activated carbon pore structure is more flourishing made from chemical activation method, compares table
Area is big and yield is high.But activated carbon prepared by this method can remain medicine, need cyclic washing, and chemical activating agent has corruption to equipment
Erosion is acted on, and will also result in certain environmental pollution.
In order to obtain the activated carbon of better quality, while reducing pollution of the preparation process to environment, people have carried out largely
Research work.It is the sturdy basis that the development of activated carbon preparation is established from the optimization for choosing technique of raw material.China is
Large agricultural country, has substantial amounts of agriculture and forestry organic waste material to produce every year, and these agriculture and forestry organic waste material utilization rates are general all than relatively low, cause money
The significant wastage in source, while also resulting in very big destruction to environment.Contain substantial amounts of cellulose and hemicellulose in agriculture and forestry organic waste material
Element, and these exactly prepare the best raw material of activated carbon, using agriculture and forestry organic waste material preparing active carbon, not only solve environmental pollution
Problem, and be to develop a circular economy, realize the effective way of agricultural sustainable development.However, passing through agriculture and forestry organic waste material at present
The process for preparing activated carbon has focused largely on Properties of Activated Carbon optimization, and pays close attention to not enough to preparation process problem of environmental pollution, grinds
Study carefully object also mainly to carry out around activated carbon quality-improving.
