-
Iodine Value: Usually ranging from 600 to 1000mg/g. A high iodine value indicates its relatively strong adsorption ability and its capacity to adsorb a large number of organic waste gas molecules.
-
Specific Surface Area: Up to 800 - 1500m²/g. The huge specific surface area provides sufficient sites for adsorption reactions.
-
Compressive Strength: The compressive strength is generally greater than 0.8MPa, which can ensure that during the use process, especially under circumstances such as air flow impact and equipment installation, the structure remains intact and is not easily broken.
-
Pore Volume: The pore volume is around 0.3 - 0.8cm³/g. An appropriate pore volume is conducive to the diffusion and adsorption of gas molecules within the pores of the activated carbon.
-
Loading Amount of Active Components: Depending on different catalytic requirements, the loading amount of precious metals (such as platinum, palladium, etc.) is generally between 0.1% and 5%, which can effectively catalyze the oxidation of adsorbed organic pollutants.
It is mainly used for the purification treatment of various organic waste gases. For example, it is applied to the treatment of waste gases containing volatile organic compounds (VOCs) such as benzene series compounds, ketones, esters, alcohols, and aldehydes generated in industries like petrochemical, coating, printing, pharmaceuticals, rubber, and plastics. In a catalytic combustion device, it first adsorbs the organic pollutants in the waste gas. After reaching saturation, the catalytic oxidation reaction is initiated by increasing the temperature and other means, converting the adsorbed organic substances into harmless carbon dioxide and water, thus achieving in-depth purification of waste gas and resource recovery and utilization.
-
Adsorption - Catalysis Synergistic Effect: Integrating the functions of adsorption and catalysis, it first adsorbs and then catalytically oxidizes, improving the treatment efficiency of organic waste gas, reducing the treatment cost, and decreasing secondary pollution.
-
High Low-Temperature Catalytic Activity: The loaded active components can catalytically oxidize the adsorbate at a relatively low temperature (usually 200 - 400℃). Compared with traditional combustion methods, the energy consumption is significantly reduced, and the requirements for equipment materials are also relatively lower.
-
High Adsorption Capacity and Fast Adsorption Rate: The large specific surface area and abundant pore structure endow it with a high adsorption capacity and a fast adsorption rate for organic waste gas, enabling it to rapidly reduce the pollutant concentration in the waste gas.
-
Good Mechanical Stability: The honeycomb structure gives it relatively high compressive strength and anti-wear ability. Under long-term use and air flow impact, it can still maintain structural stability and extend its service life.
-
Renewable and Recyclable: Through the catalytic oxidation reaction, the regeneration of the adsorbent is realized, and it can be recycled multiple times, further reducing the operating cost and waste disposal cost.
-
Physical Characteristics: It has a regular honeycomb shape with evenly distributed pores. The pore size can be customized according to requirements (common pore sizes are 1 - 5mm). It is lightweight, with a density generally ranging from 0.3 to 0.6g/cm³, facilitating installation and transportation.
-
Chemical Characteristics: It has relatively stable chemical properties and is not easy to lose its activity due to chemical reactions with other components in waste gas under normal use conditions. However, under extreme conditions such as high temperature, strong acid, or strong alkali, its performance may be affected. The loaded active components have specific catalytic activities that can promote the oxidation reaction of organic pollutants. During the reaction process, their own properties and structures will change to some extent, but they can recover part of their activities under appropriate conditions.
-
Raw Material Selection and Pretreatment: Select high-quality activated carbon raw materials, such as coconut shell activated carbon, coal-based activated carbon, etc. After screening, crushing, grinding, and other processes, impurities are removed and the particle size is adjusted to ensure the purity and activity of the raw materials.
-
Loading of Active Components: Processes such as the impregnation method, ion exchange method, or chemical vapor deposition method are adopted to uniformly load the active components onto the pore surfaces and interiors of the activated carbon. In the impregnation method, the activated carbon is impregnated in a solution containing the precursor of the active component, and after drying and calcination treatments, the precursor decomposes and transforms into the active component. The ion exchange method utilizes the functional groups on the surface of the activated carbon to exchange with the active component ions. The chemical vapor deposition method makes the gaseous precursor of the active component react and deposit on the surface of the activated carbon.
-
Molding and Processing: The activated carbon loaded with active components is mixed evenly with an appropriate amount of binder (such as cellulose, phenolic resin, etc.), and then a honeycomb-shaped blank is made through the extrusion molding process. Subsequently, the blank is dried to remove moisture and increase its strength.
- Post-Treatment and Activation: The dried honeycomb activated carbon blank can be subjected to high-temperature calcination or other activation treatments as needed to further optimize the pore structure and improve the adsorption performance and catalytic activity. Meanwhile, the product undergoes quality inspection, including the detection of indexes such as iodine value, compressive strength, and content of active components, to ensure that the product meets relevant standards and requirements before being packaged and shipped out.
