Why choose 800 iodine value Honeycomb activated carbon To absorb waste gas?

1. Policy level

The Notice on the Ministry of Ecological Environment's Printing and Distributing the Key Program for the Treatment of Volatile Organic Compounds in 2020 states that:. Currently used in waste gas treatment equipment Activated carbon There are two kinds, one is columnar activated carbon, the other is honeycomb activated carbon. The iodine value of columnar activated carbon can reach 800mg/g. However, at present, most of the waste gas treatment equipment in the market uses catalytic combustion equipment, and the treatment effect is very good. Honeycomb activated carbon is used in these equipment, but the honeycomb activated carbon cannot reach 800mg/g due to production process problems. At present, the honeycomb activated carbon in the market reaches 600mg/g, and it is recommended to increase the carbon tetrachloride index ≥ 55%.

Reply: At present, there are a large number of activated carbon with low quality and poor adsorption effect on the market, which is difficult to meet the requirements of volatile organic compounds (VOCs, Realize effective emission reduction of VOCs. For granular, columnar and other activated carbon adsorption, activated carbon with iodine value not less than 800 mg/g shall be selected; Absorbed by honeycomb activated carbon

2. User level

The 800 iodine value honeycomb activated carbon has larger specific surface area, unique pore structure, stable surface chemical functional groups, resistance to acid and alkali corrosion, hydrophobicity, and regeneration after failure. Because of its unique honeycomb structure, it also has the advantages of high porosity, uniform gas distribution, larger geometric surface area, short diffusion path, wear resistance, and strong dust pollution resistance.

Compared with ordinary honeycomb activated carbon with 800 iodine value, honeycomb activated carbon has stronger instantaneous grasping ability, and better adsorption effect for VOCs and non methane total hydrocarbons with medium, low and high concentrations.

Secondly, honeycomb activated carbon with 800 iodine value reduces the replacement frequency of activated carbon due to its higher effective ingredients, lower impurities and longer service life. After the adsorption saturation failure of activated carbon, regeneration and recycling can be realized, which greatly reduces the cost of hazardous waste of the enterprise, thus reducing the operation and management costs of the enterprise as a whole. And conform to the strategy of sustainable development.
