MODIFIED AC & CHEMICAL ADSORBENT

Clarkson can not only supply modified activated carbon, but also other chemical adsorbent, such as activated alumina and zeolite particles/molecular sieves. They can efficiently remove over 230 kinds of irritating, odorous and corrosive toxic and harmful gaseous pollutants such as formaldehyde (CH₂O), ozone (O₃), sulfur dioxide (SO₂), hydrogen sulfide (H₂S), ammonia (NH₃) and TVOCs. Organic pollutants, inorganic pollutants, chlorine and chlorination by-products, odors and colors, microorganisms and viruses, radioactive substances, etc. in liquid-phase treatment; decolorization in food, beverage and pharmaceutical industries, and gas separation and purification etc.

Raw Material：Coal, wood, coconut shells, alumina

Chemically Modified AC

Chemically modified AC is an adsorption material that loads specific chemical substances on the surface of activated carbon through physical or chemical methods. It has a stronger directional adsorption capacity or catalytic function, enabling it to achieve more efficient adsorption or conversion of specific pollutants (such as gases, heavy metals, organic substances, etc.). Its adsorption principle is the combined effect of physical adsorption, chemical adsorption and catalytic reaction.

Unlike simple physical adsorption, in chemical adsorption, pollutant molecules are converted into harmless salts and remain inside the adsorption filter material. Once pollutants are removed from the environment, they cannot return to the air or liquid, effectively preventing secondary pollution of the environment.

Activated Alumina

Activated alumina is a porous and highly dispersed solid spherical particle with uniform particle size, smooth surface, high mechanical strength and strong hygroscopicity. It has a large surface area (150-400㎡/g), and possesses better adsorption, absorption and oxidation capabilities for pollutants. Moreover, it has excellent chemical stability at room temperature and demonstrates good corrosion resistance in corrosive media such as acids, alkalis and salts. It is mainly used as an adsorbent, water purifier, catalyst and catalyst carrier, and is widely applied in the fields of petrochemicals, fine chemicals, biology and pharmaceuticals.

Molecular Sieve

Zeolite molecular sieves are artificially synthesized hydrated silicoaluminates with the function of screening molecules. Molecular sieves with different pore sizes can separate molecules of different sizes and shapes. Therefore, zeolite molecular sieves are like sieves for gas and liquid molecules, determining whether they are adsorbed based on the size of the molecules.

It features high adsorption capacity, strong selectivity, high-temperature resistance, ion exchange performance, excellent acid catalytic activity, and good thermal and hydrothermal stability. It can be made into catalysts with high activity and selectivity for many reactions and is widely used in organic and petrochemical industries. It is also receiving increasing attention in waste gas purification.
