What is activated bleaching earth
Activated bleaching earth is an important industrial adsorbent composed primarily of montmorillonite and other minerals. It is mainly used in refinery, food oil processing, chemical industry and sugar factory for decolorization and cleaning.
In which areas is it used?
**Food Oil Processing**: Bleaching earth is widely used for decolorizing and purifying food oils. During the refining process, food oils contain impurities and colorants, which fuller's earth can effectively adsorb to make the oil clear and transparent.
**Refinery**: In the petroleum processing industry, bleaching earth is used to remove contaminants such as wax, resins, asphalt, paraffins and dyes, thereby improving the quality and transparency of fuels.
**Chemical Industry**: Bleaching earth is used in the chemical industry to decolorize chemical products such as fatty acids, glycerol, amino acids and as a catalyst in organic syntheses.
**Sugar factories**: In sugar factories, bleaching earth is used to decolorize syrups to remove colorants and impurities and to improve the quality of the sugar.
Where does activated bleaching earth come from?
The main producing countries for bleaching earth worldwide are the USA, China, India, Brazil and Russia. China and India are the leading producers of bleaching earth and dominate the market. The production capacity for bleaching earth is mainly concentrated in large mines and processing plants in these countries.
What will be the future development of activated bleaching earth?
In terms of current usage, fuller's earth is still an indispensable material in food oil processing, refinery, chemical industry and sugar factory. With the continuous development and expansion of these industries, the demand for bleaching earth is also increasing. At the same time, some countries are continuously working on innovations and improvements in the production and processing of bleaching earth to improve the quality and performance of products and meet market needs.
