Coconut Shell Activated Carbon for Air Purification and Electric Power Industry PRODUCT DESCRIPTION Coconut shell activated carbon  is a kind of activated carbon with better air filtration effect. The coconut shell activated carbon of Yihang brand used for air purification and electric power industry has high-efficiency air purification function. Yihang desulfurizated activated carbon has a very high H2S removal capacity. It can also be used for Garbage burning and Solvent recovery. Technical Principle Coconut shell   activated carbon  used for air purification has the function of combining physical adsorption and chemical decomposition to decompose harmful gases such as formaldehyde, ammonia, benzene, cigarettes, oil fume and various peculiar smells in the air, especially carcinogenic aromatic substances. Coconut shell activated carbon used for air purification has extremely strong adsorption capacity. It is a commonly used adsorbent, catalyst or catalyst carrier, a...

   Production of carbon rich solids through pyrolysis Both charcoal and activated carbon are made through a process called pyrolysis, in which a raw material - in this case, a carbon-containing substance - is subjected to high temperatures in the absence of oxygen, causing it to thermally decompose into char, or  carbon-rich solids . The lack of oxygen is key to the process, as too much carbon dioxide is introduced and caused to burn off as a gaseous product. In pyrolysis, the starting material (or "feedstock") and processing conditions can be adjusted to tailor the carbon-based product to the specific application. The quality of the feedstock can also affect its processing efficiency, end application, and possible environmental impact. For example, other biomass sources may include unknown biomass and materials collected from municipal waste streams. Processing conditions include pyrolysis temperature and duration, particle size, moisture content, and activation -- impro...

Charcoal and activated carbon are two forms of carbon that have a lot of overlap and have very similar compositions and production methods. What are the differences between them?   Overview of charcoal and activated carbon   Charcoal Charcoal is considered to be a metamorphic form of graphitic carbon that is produced as a residue when carbon-rich materials are partially burned or burned in the absence of oxygen. Carbon-rich materials include mainly materials such as wood. One thing to note is that charcoal is not naturally occurring in nature. That is, it is a man-made product. Even if charcoal is found in nature, it is likely to have been produced due to the effects of high temperatures such as forest fires.   Activated carbon Activated carbon  is a carbon-rich solid that is extracted by pyrolysis from biomass or other carbon-containing materials such as coal or tar pitch. In this process, the carbon material is also "activated" through a process that greatly increa...

Activated carbon is a highly porous substance that attracts and retains organic chemicals in it. The medium is created by first burning a carbonaceous material that does not contain oxygen, which produces carbon "char". Next, the "carbon" is chemically or physically treated to form a series of interconnected pores within the carbon. The large surface area of this internal pore network results in a very large surface area that can attract and hold organic chemicals. We offer activated carbon made from bituminous coal, lignite,   coconut shell   and wood.     What does activated carbon do? Activated carbon attracts and retains organic chemicals from vapor and liquid streams to  remove unwanted chemicals . It is not very capable of treating these chemicals, but is very cost effective in treating large volumes of air or water to remove dilute concentrations of contaminants. On a better note, when individuals ingest chemicals or are experiencing food poisoning, they...

Coconut shell activated carbon is made of high-quality coconut shell as raw material and refined through a series of production processes. The appearance of coconut shell activated carbon is black and granular. It has the advantages of well-developed pores, good adsorption performance, high strength, easy regeneration, economical durability, etc. However, due to problems such as the origin of coconut shell, the price is higher than that of conventional wooden activated carbon. Coconut Shell Activated Carbon The products are mainly used for the purification, decolorization, dechlorination, and deodorization of drinking water, purified water, wine, beverages, and industrial sewage; it can also be used for the desulfurization of the oil refining industry. Application 1. Coconut shell granular activated carbon is often used in gas phase adsorption, usually by letting air flow through the activated carbon layer for adsorption. According to the state of the activated carbon layer in the adso...

Activated Carbon Pellets for Air Purification PRODUCT DESCRIPTION Yihang Activated carbon pellets  for air purification is made of high quality anthracite coal, wood or coconut shell.

In the context of rapid economic development, the impact of environmental pollution is becoming increasingly serious. The water pollution caused by sewage discharge is the most direct and serious consequence because it is related to the life safety and quality of life of people. Therefore, it is very important to reduce the discharge of harmful substances in wastewater and increase the utilization rate of recyclable wastewater. So, how to reduce COD in wastewater?   1. What is COD? Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples, which is often expressed by the symbol cod. Cod is expressed in mg / L. COD values detected by water quality monitoring instruments can be divided into five categories. Among them, COD of the first and second categories is less than 15mg / L, which basically meets the drinking water standard. The remaining three COD values can not be used as drinking water. The third t...
