Activated Carbon for VOCs Removal
Volatile organic compounds (commonly referred to as VOCs) are a class of organic chemicals that are characterized by high vapor pressure at room temperature. This property causes a large amount of volatile substances to evaporate into the atmosphere, causing air pollution and posing various health risks.

Volatile organic compounds (commonly referred to as VOCs) are a class of organic chemicals that are characterized by high vapor pressure at room temperature. This property causes a large amount of volatile substances to evaporate into the atmosphere, causing air pollution and posing various health risks. VOCs are present in many industrial processes and everyday products, so controlling and reducing VOCs is essential for environmental protection and public health.
Activated carbon can be used in a variety of applications to effectively manage VOC emissions: VOC Removal, Odor Control, Acid Gas Removal,Multi-pollutant Adsorption,Personal Protective Equipment.
Pelletized and honeycomb activated carbon products capture and remove a wide range of VOCs from industrial emissions, ensuring cleaner air. Activated carbon impregnated with an alkaline solution (sodium or potassium hydroxide) targets and neutralizes volatile compounds that cause odors. Activated carbon with a high iodine value is used to remove acid gases from process streams in the oil and gas or biogas industries. High-quality activated carbons can be used in integrated systems to treat multiple pollutants simultaneously, improving overall air quality.Granular coconut shell activated carbon filters used in respirators and escape hoods protect workers, first responders, and military personnel from harmful gases.
As an important adsorption material, columnar activated carbon has a wide range of applications in environmental protection, chemical industry, medicine and other fields. Its iodine value and CTC value are two important indicators for measuring the performance of columnar activated carbon, which have a decisive influence on the adsorption effect and service life of activated carbon. This article will analyze and discuss the iodine value data and CTC data of columnar activated carbon in detail.
First, let's understand the iodine value data of columnar activated carbon. Iodine value refers to the adsorption capacity of activated carbon to iodine, which is an important parameter for measuring the adsorption performance of activated carbon. Generally speaking, the higher the iodine value of activated carbon, the stronger its adsorption capacity. Depending on different production processes and raw materials, the iodine value of columnar activated carbon will vary. In the market, the iodine value range of common columnar activated carbon is generally between 500-1200mg/g. And the iodine value of high-quality columnar activated carbon can even reach a higher level.However, it should be noted that the iodine value is not the only standard for measuring the performance of activated carbon. In practical applications, factors such as the pore size distribution, specific surface area, and mechanical strength of activated carbon also need to be considered. Therefore, when selecting columnar activated carbon, in addition to paying attention to the iodine value data, other performance indicators should also be considered comprehensively.
Next, let's explore the CTC data of columnar activated carbon. The CTC value is an indicator of the adsorption capacity of activated carbon for carbon tetrachloride, and it is also one of the important parameters for measuring the performance of activated carbon. The high or low CTC value directly affects the application effect of activated carbon in gas phase adsorption, solvent recovery and other fields. High-quality columnar activated carbon usually has a higher CTC value and can effectively remove harmful substances in exhaust gas.
In the market, columnar activated carbons of different brands and models will also have different CTC values. Generally speaking, the CTC value of high-quality columnar activated carbon can reach more than 100%, or even higher. However, some low-end products or inferior products often have lower CTC values and cannot meet the needs of practical applications.
In addition to iodine value and CTC value, other performance indicators of columnar activated carbon are also worthy of attention. For example, specific surface area is one of the important indicators to measure the adsorption capacity of activated carbon. The larger the specific surface area, the stronger the adsorption capacity. In addition, mechanical strength is also one of the key factors affecting the service life of activated carbon. Activated carbon with high mechanical strength is not easy to break during use and can maintain long-term adsorption performance.
In addition, the application range of columnar activated carbon is also very wide. In the field of environmental protection, columnar activated carbon can be used for waste gas treatment, sewage treatment, etc., to effectively remove pollutants and protect the environment. In the chemical industry, columnar activated carbon can be used for catalyst carriers, solvent recovery, etc. to improve production efficiency and product quality. In the pharmaceutical field, columnar activated carbon can be used for decolorization and deodorization in the pharmaceutical process to ensure the quality and safety of drugs.
Activated carbon is not only limited to the field of environmental protection. Its powerful adsorption properties are also widely used in medical, food processing and other fields. With the development of science and technology in the future, the application fields of activated carbon will be broader.
