Description

A kind of method that environmentally friendly potent adsorbent is prepared with pig blood curd
Technical field
The invention belongs to environmentally friendly material preparation and application technical field, and in particular to a kind of pig blood curd basic ring border The preparation method of the potent adsorbent of friendly.
Background technology
Hydro-thermal charing is used for simulation accelerated coalification and reacted earliest, is a kind of using biomass or its component as raw material, is sealing Pressure vessel in using water as solvent, and reaction medium synthesizes calorific value under 150 ~ 375 DEG C and self-generated pressure（HHV）High rich carbon The process of solid product.Stalk, shell, wood chip and thirdly big component：The biomass such as cellulose, hemicellulose and lignin, it is The current primary raw material for preparing hydro-thermal charcoal.
In recent years, hydro-thermal charring has become a kind of efficient biomass preprocessing means and the conversion of biomass full constituent Method.Hydro-thermal charring process has following significant advantage：Biomass material moisture is not limited, it is not necessary to which it is entered Row drying process, substantial amounts of pretreatment expense is saved；Hydro-thermal carbonizes the oxygen remained in big content of starting materials, nitrogen, product table Abundant oxygen-containing, nitrogen-containing functional group are contained in face, can be applied to multiple fields；Processing equipment is simple and convenient to operate, can using scale Modulability is strong.As biomass resource hydro-thermal charing principal product, hydro-thermal charcoal can be used in Heavy Metals in Waters ion absorption, The preparation of high-performance porous charcoal, as good presoma for preparing solid acid catalyst and as electrode material, clean energy resource etc. Purposes.
China is pig-breeding and consumption big country, the caused accessory substance pig blood about 1,500,000 by pig carcass every year Ton.The pig blood curd formed after pig blood solidification is a kind of common traditional Pig's blood products, and it has higher nutritive value, still Due to the edible upper mouthfeel of pig blood curd, compared with duck blood etc., other animal blood coagulation products are poor, thus pig blood its cheap market price.Although Pig blood has been applied in terms of medicine at present, is such as processed to protein peptides, but utilization rate still very little, most of pig blood raw material It can directly be outwelled, both cause huge waste, pollute environment again.Using pig blood curd as raw material, prepared using hydro-thermal charring process There is not been reported both at home and abroad for the correlative study of the environmentally friendly rich potent adsorbent of carbon of the surface rich in active functional group group.
The content of the invention
It is an object of the invention to provide a kind of method that environmentally friendly potent adsorbent is prepared with pig blood curd, it is Using the byproduct pig blood curd of pig-breeding as raw material, in a mild condition a step prepare surface have it is abundant it is oxygen-containing, contain The method of the environmentally friendly rich carbon adsorbent of the functional groups such as nitrogen.Prepared adsorbent heavy metal ion or dyestuff point Son shows efficient removing performance, has wide application in the field such as environmental pollution improvement and electrode material for super capacitor Prospect, a new way is provided for the high-valued trans-utilization of pig blood, there are significant economy and ecological benefits.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of method that environmentally friendly potent adsorbent is prepared with pig blood curd, it comprises the following steps：
1）Pig blood curd is pulverized after drying, obtains pig blood dry powder；
