The characteristics of common oil adsorbents
The physical structure of the adsorbent is a porous solid.
And the active surface is not only the outer surface of the particle, but mainly composed of numerous micropores of various pore sizes and the surface of the capillary inside the adsorbent particle.
Therefore, the particles of the adsorbent should have a relatively large surface area. 1g of adsorbent powder is hundreds of square meters.
For example, the inner surface area of 1g of activated carbon is 1000㎡, the inner surface area of 1g of clay is 100㎡-300㎡, and the inner surface area of 1g of silica gel is 300㎡-450㎡.
The finer the grinding degree of the adsorption powder, the larger the surface area and the stronger the adsorption capacity.
