Description
Technical field:
The present invention provides a kind of preparation method of Gorgon fruit based active carbon material, belongs to field of charcoal material.
Background technique:
Active carbon is to use containing the material based on charcoal as raw material, made of activated and carbonization, is handled through series of processes
It will form the different flourishing hole of shapes and sizes in the carbon crystal compartment of active carbon afterwards, suction-operated occurs mainly in its hole
The surface of gap.The specific surface area of active carbon is generally up to 500~1700m2/ g, the adsorbance of active carbon not only with specific surface area
It is related, but also depend on the construction and distribution situation in its hole.
The regular pore-size distribution regulation of active carbon and its application study are one of forward position and hot spot of current Carbon Materials research.?
While preparing active carbon with high specific surface area, regulation is oriented to its pore structure, not only facilitates active carbon theoretical system
It is abundant and perfect, and facilitate the professional application approach for further expanding active carbon.In active carbon micro-structure aperture size and
Quantity directly affects the adsorption capacity of active carbon, and research orientation regulation activity charcoal pore-size distribution increases its functionality absorption and makees
With, such as the storage of decolorizing and refining, gas, medicament slow release and electrochemical action, the unique purposes of active carbon is formed, has been obtained wide
The very big concern of big science worker.Mesopore activated carbon makes it be more suitable for fermentation liquid pure because having biggish aperture and Kong Rong
Change, the absorption of natural macromolecular pigment etc.;For microporous activated carbon because having relatively narrow aperture and huge specific surface area, suitable ten are Gao Rong
Porous material is used in the amount small molecules such as capacitor electrode material and formaldehyde, natural gas absorption.
Common active carbon can be divided into wood activated charcoal (such as cocoanut active charcoal, apricot shell active carbon, wood powder by raw material difference
Charcoal etc.), mineral raw material active carbon (various coals and petroleum and its processing product be raw material made of active carbon), other raw materials
Manufactured active carbon (as utilized active carbon made of scrap rubber, waste plastics etc.).In recent years, both at home and abroad with various cheap agricultures
Woods waste is raw material, has carried out the research for preparing wood activated charcoal.Agriculture and forestry organic waste material is easy to get with cheap, material to be filled
The advantages that foot and carbon content rate are high.It effectively utilizes agriculture and forestry organic waste material and prepares active carbon, can not only save material, but also advantageous
In the sustainable use of resource.Agriculture and forestry organic waste material raw material includes: walnut class, bamboo class, stalk class and lignin etc..Isilay
Ozdemir et al. uses grapevine to utilize ZnCl as raw material2Being prepared for specific surface area as activator is 1411m2/ g's
Grapevine matrix activated carbon.In the priming reaction for preparing wood activated charcoal, the various forms of keys that can be formed between substance, from
And various functional groups are generated, therefore, the general absorption property of the wood activated charcoal of different material preparation has larger difference.
