Hydrophobic Silica Gel
Hydrophobic silica gel is a kind of highly active inorganic silica adsorption material, which is insoluble in water and any solvent, non-toxic, tasteless, stable in chemical properties, and does not react with other substances except strong alkali and acid. Compared with activated carbon adsorbent, it has the characteristics of low adsorption heat, stable chemical properties, safety and environmental protection, high mechanical strength and long service life.

Characteristics

Hydrophobic silica gel is a kind of highly active inorganic silica adsorption material, which is insoluble in water and any solvent, non-toxic, tasteless, stable in chemical properties, and does not react with other substances except strong alkali and acid. Compared with activated carbon adsorbent, it has the characteristics of low adsorption heat, stable chemical properties, safety and environmental protection, high mechanical strength and long service life.


Application: 

Hydrophobic silica gel has a weak polar surface, which is easy to absorb hydrocarbons and can be desorbed under vacuum. It is non combustible and can ensure the safety of oil depot and gas station. The recovery efficiency of oil and gas is high, and the recovery of non methane hydrocarbons can reach more than 99%. The emission of non methane hydrocarbons is less than 1g/m3.
