Structure Characteristics of Activated Bleaching Earth 

  Activated Bleaching Earth has the layered structure among molecules with many irregular holes on the surface;it has an extremely large specific area. This product is a type of sub-white powder,which is odorless,tasteless,non-toxic and the stacking density is 0.7 to 1.1 g/ml.it is dispersed, greasy to touch.it is insoluble for the water,organic solvents and various oils and lipids.it has relatively strong characteristic of ion interchangeability,selective adsorption,hydrophilic,surface activity and catalytic.it begins to lose crystal water when it is heated to more than 300 degrees,and its structure will be changed,which will exert an impact on the decolorization effect. The absorption function will be reduced when it is kept too long or moisturized.It can be used to absorb and remove the carcinogenic substance from animal and vegetable oil,such as pigment,aflatoxin B1(AFTB1) and 3-4 benz(a)pyrene.It also can be used to absorb and remove the asphaltene,neutral colloid,sulfide,olefin naphthenic acid mineral,and basic nitrogen outof lubricating oil,to improve the durability and safety of the lubricating oil and to enhance the corrosion resistance.

Application
  1.Used in refinement of crude edible, animal and vegetable oils;it can be used for decolorization and purification.it can remove the harmful pigment,aflatoxin,phosphatide,saponin,colloid,and cotton acid from the crude oil to make it high-grade edible oil.
  2.Used in decolorization and refinement of crude edible animal and vegetable oil for industrial purpose
  3.Used in the petroleum industry,it is used for the decolorization,refinement and purification of crude diesel,kerosene,gasoline,grease,paraffin wax,white oil,lubricating oil,vaseline,etc.
  4.Used in regeneration of crude industrial waste oil of mineral oil like machine oil and lubricating oil.
  5.Used in decolorization and refinement of resin,natrum and polyether.
  6.Used in the food industry,the clarificant for monosodium glutamate(MSG),vitamins,grape wine and sugar juice,andit is also used in the beer stabilityprocessing,saccharification processing,and sugar juice purification.
  7.Used in separation ofolefin in arene and alkene,petroleum schizolysis and polymerization and catalysis of olefin.
