Description
Technical field
The present invention relates to a kind of method utilizing rice husk to prepare high dispersancy nano white carbon, belong to Nano carbon white and prepare
Technical field.
Background technology
Biomass energy is a kind of preferably clean reproducible energy, has the feature such as carbon dioxide zero discharge, environmental protection,
Development and utilization biomass energy, to slowing down greenhouse effect, reduces atmospheric pollution, alleviates Pressure on Energy significant.Rice husk
The higher value application of these agricultural wastes is possible not only to solve the pollution problem of a large amount of agricultural wastes, it is also possible to create for society
Make more wealth, contribute to alleviating environmental problem and energy crisis.Rice husk is due to rich in natural undefined structure Si02, it is system
The standby current most widely used general inorganic nano material maximum with industrialization yield, the ideal material of Nano carbon white.
Rice husk is Si0 in all living species of nature2Content maximum, these Si02Mainly it is present in unformed shape
In rice husk or rice hull ash, can separate from rice husk or rice hull ash under conditions of more gentleness, be a kind of preferably silicon
Source, and when preparing silica-base material, energy consumption is low, cost is little, can prepare various Si02 series products, and such as white carbon, nanometer is white
White carbon black, aeroge, silica gel etc..Rice husk, due to the Si02 rich in unformed state, is to prepare the silicon such as white carbon, zeolite, molecular sieve
The ideal material of matter chemicals, the content of metallic compound therein and carbonaceousfuel component is then to restrict these siliceous chemicals performances
Principal element.As a example by rice husk base white carbon, in rice husk, the content of metal impurities and carbonaceousfuel component directly affects white carbon
The purity of product and serviceability thereof.Therefore, rice husk is carried out suitable pre-treatment, to improve rice husk activity, reduce in rice husk
The content of metal impurities or carbonaceousfuel component has very important effect to the utilization of composition siliceous in rice husk.Close melon rice at present
In shell, the extraction of Nano carbon white is still in the preliminary research stage, and existing technology or properties of product are single, and impurity content is high,
Or severe reaction conditions, it is difficult to control, energy expenditure is big, or particle diameter is relatively big, and dispersibility is very poor, prepares so limiting this
The large-scale application of technology.
Owing to Nano carbon white has greatly specific surface area and surface energy, owing to generally existing between particle in preparation process
Van der Waals force, Coulomb force even chemical bond, easily reunite so that powder particle can not be uniform with nanometer grade
And stable dispersion, when causing applying, due performance reduces or loses.Tradition rice husk base white carbon and the system of Nano carbon white
Preparation Method also exists that properties of product are single, product purity is low, particle diameter is thick, be prone to the problems such as reunion, especially product pellet
Reunite and scattering problem is the difficult point in current Nano carbon white applied research and focus.
Summary of the invention
The technical problem to be solved: for tradition rice husk base Nano carbon white at present, performance is single, purity
Low, particle diameter is thick, the drawback of easy reunion, it is provided that a kind of by rice husk warm water immersion, then pulverize after pickling, will obtain
Powdered rice hulls and microorganism mixed fermentation, through the method that high temperature pyrolysis prepares Nano carbon white.The present invention is gone by water logging, pickling
Except the metal impurities in rice husk, ash grade, improving Nano carbon white purity, polished and microbial reaction removes it further
In organic principle, and utilize fermentable polysaccharide white carbon surface formed layer protecting film, reduce between its surface hydroxyl
Active force so that it is change of will not mutually reuniting is big, after remove residual impurity through high temperature pyrolysis, finally give Nano carbon white,
Rice husk base Nano carbon white purity is low, particle diameter is thick, the problem of easy reunion, has splendid dispersibility to solve tradition.
