Which Activated Carbon Should I Choose For Industria Gas Purification?

一.Refine your selection based on the pollutant and process.

Beyond the physical form, you also need to identify more detailed performance specifications based on your specific purification objectives and process.

1. Recovering Valuable Solvents
If your goal is to recover organic solvents (such as benzene, toluene, and acetone) from the production process, granular, pillared activated carbon is a common choice. In this case, it's important to consider the regeneration method:

Steam regeneration: Activated carbon requires a high concentration of submicropores (1.5-2.0 nm) and some mesopores (>2 nm) to ensure efficient regeneration.

Hot air/nitrogen regeneration: Pore structure requirements vary.

Pressure reduction desorption: For oil and gas recovery, for example, activated carbon with well-developed mesopores is required.

2. Purifying VOCs of Different Molecular Sizes
The size of the pollutant molecules directly determines the pore structure of the activated carbon required.

For small molecule pollutants (such as benzene, toluene, and xylene), activated carbon with well-developed micropores is suitable.

For larger molecule pollutants (such as styrene and gasoline vapor), activated carbon with more mesopores is suitable.

3. Handling High-Demand or Special Operating Conditions

High Strength and High Purity: Studies have shown that coconut shell activated carbon is the preferred choice for removing hydrocarbon impurities in the purification of natural gas sweetening amine liquid due to its excellent pore structure and adsorption properties.

Practical Advice for Industrial Applications
Key indicators to focus on: iodine value (reflecting total adsorption capacity), carbon tetrachloride adsorption rate (reflecting adsorption capacity for organic matter), mechanical strength (influencing service life), and specific surface area are key parameters.
