The effect of nutshell activated carbon on waste gas treatment

Nutshell activated carbon is mainly made of nutshells (commonly coconut shells, apricot shells, cherry shells, jujube shells, walnut shells, olive shells, etc.) as raw materials, activated carbon products processed by carbonization, activation, and refinement. The appearance is indeterminate Granular.

Coal-based activated carbon uses fine coal as the raw material and is refined and processed through a series of processes such as carbonization→cooling→activation→washing with advanced technology and equipment. The shape is divided into granular, columnar, and powdery activated carbon products.

Due to the different production raw materials, coal-based activated carbon and nutshell activated carbon will be different in product characteristics, technical characteristics, production processes, etc., which affects different application fields.

However, in the treatment of waste gas, activated carbon from husk is better than activated carbon from coal. The sources of waste gas in electronics factory workshops are mainly benzene, toluene and xylene, non-methane total hydrocarbons, ammonia, and formaldehyde.activated charcoal wholesale uk In addition, there are some fuel incineration waste gas, mainly inorganic substances, nitrogen oxides, sulfur dioxide, smoke and so on. The content of triphenyl and sulfur dioxide in the waste gas of the workshop is relatively high.

Therefore, the production materials of nutshell activated carbon for waste gas treatment need to select good wood, go through deep activation and pore size adjustment process, so that the activated carbon has abundant pores, and the pore diameter is slightly larger than the toxic gas. The iodine value of nutshell activated carbon needs to reach 900mg/g, Surface area>1000m2/g, strength reaches 99%. The adsorption effect of nutshell activated carbon for waste gas treatment is good, which is obvious to all. Compared with coal-based activated carbon, it is more reliable and more effective.

Compared with nut shell activated carbon, coal-based activated carbon contains more heavy metals and ash, and the purity of the product is relatively low. Because it is mainly produced by physical methods, the pores are mainly micropores, which are suitable for small molecule adsorption. China's petrochemical, metallurgy, printing and dyeing, sewage treatment and other industrial fields.https://yrdcarbon.com

The husk activated carbon has low ash content, less impurities, and is easy to purify. It is easy to adjust the pore distribution structure of activated carbon under the chemical production process. Micropores and mesopores are developed and widely used, especially in food, beverage, medicine, etc., which require adsorption performance Application in fields with higher requirements for product indicators. Nutshell activated carbon is an activated carbon product that cannot be replaced by coal-based activated carbon.
