Different production processes: activated clay is a bentonite product after acidification treatment, while granular clay is made of activated clay as the main raw material through scientific formula and chemical treatment. Its appearance is amorphous small particles. It has higher specific surface area and particle strength than activated clay, stable performance, good selectivity, high adsorption capacity, reduced the oil carrying rate of the product, and is more convenient for transportation and use.

Different physical properties: granular clay has a granular structure with a large surface area, which is more conducive to the performance of adsorption and filtration, while activated clay has a powdery structure with a small surface area, but the specific surface area of activated clay is larger than that of granular clay, which has a good effect of adsorption and clarification.

Different uses: activated clay is mainly used for decolorizing various oils and fats to increase the beauty of grease color, while granular clay is mainly used for aromatics purification in petrochemical industry, aviation kerosene refining, lubricating oil, base oil, diesel oil and other oil products refining, removing residual olefins, colloids, asphalt, alkaline nitrides and other impurities in oil products, which is more widely used.
