Description
Technical field
The invention belongs to compound fertilizer granulating technical field, in particular it relates to a kind of grease with modified attapulgite as carrier
Decolorising agent.
Background technology
All contain a certain amount of impurity in various animal and vegetable oils, purification and decoloration is required for before edible and commercial Application.Oil
The method that fat decolourizes is a lot, and most widely used in industrial production is adsorption decoloring method.The adsorption bleaching of grease, is exactly using certain
A little materials having to pigment compared with strong selectivity suction-operated, adsorb the pigment and other impurity in grease under certain condition,
So as to reach the purpose of decolouring.
The fat decolourizing agent applied or reported at present has：Bentonite, atlapulgite, montmorillonite, attapulgite modified, activity
Charcoal, zeolite（Chinese patent 89108326.X）, diatomite, silica gel and activated alumina etc..But these fat decolourizing agents respectively have excellent
Shortcoming, wherein the most widely used fat decolourizing agent for grease-decolor is atlapulgite, but this atlapulgite strainability
Difference, butt residual oil content is high after decolouring（Up to 30-40%）, cannot after being decolourized containing heavy metal element poisonous impurities and fat decolourizing agent
Recycle, therefore substitute need to be found.
Attapulgite modified is a kind of natural nano inorganic matter with special layers chain structure, with larger specific surface area,
Adsorptivity is strong.It is attapulgite modified with heat endurance and stronger anti-salt property higher, decoloring ability is strong, adsorption capacity
It is good, with percent of decolourization it is high, without residual acid many advantages, such as, the good reputation with " kings of thousand soil ".Modified attapulgite clay is in itself
With certain L acid sites and B acid sites, by modified, attapulgite modified acidity can be strengthened, improve it with free fat
The binding ability of the impurity such as fat acid, wax, pigment, is a kind of performance so as to effectively adsorb the impurity such as the pigment in grease
Excellent adsorbent and fat decolourizing agent.As the B of Chinese invention patent CN 101497026 disclose a kind of for producing injection
The attapulgite modified base fat decolourizing agent of soybean oil.Chinese invention patent CN 103055802A disclose a kind of with antioxygen
Change the preparation method of property modification attapulgite clay palm oil fat decolourizing agent.
Atlapulgite and attapulgite modified combination are combined not only free fatty, the wax contained in effectively removal grease
Outside the impurity such as the impurity such as matter, pigment, heavy metal element therein can also be removed.
The content of the invention
For defect of the prior art, grease-decolor is carried out with atlapulgite it is an object of the invention to be directed to, it is impossible to
The shortcoming of heavy metal element is removed, modified modified attapulgite is combined with atlapulgite grease is decolourized, and then effectively
Impurity and the heavy metal element such as free fatty, wax, pigment in removal grease.
