Silica Absorbent Granule particles have a multi microporous structure. Silica Absorbent Granule has strong adsorption capacity for leaked pollutant liquids such as diesel, gasoline, engine oil, No. 2 flotation oil, toluene, xylene, kerosene, nitrobenzene, formaldehyde, methanol and ethanol. Silica Absorbent Granule can adsorb pollutant liquid equivalent to 6 times its weight (about 5-6 kg of oil and chemical liquid can be adsorbed per kg of Silica Absorbent Granule). Silica Absorbent Granule provides a low-cost and environment-friendly cleaning scheme for emergency liquid absorption treatment of oil leakage pollution on land and at sea.
