The impact of effective pore percentage on $ CH_{4} $/$ N_{2} $ separation in coal-based activated carbon
The efficient separation of $ CH_{4} $/$ N_{2} $ using activated carbon depends on the strict regulation of carbon pore structure. However, the relationship between pore structure and separation performance remains inadequately explored in the literature. This study employed a sample set comprising...

| 520 | |a The efficient separation of $ CH_{4} $/$ N_{2} $ using activated carbon depends on the strict regulation of carbon pore structure. However, the relationship between pore structure and separation performance remains inadequately explored in the literature. This study employed a sample set comprising 38 coal-based granular activated carbons with diverse pore structural parameters to investigate the impact of pore size distribution on $ CH_{4} $/$ N_{2} $ separation using advanced statistical methods. Through Pearson’s correlation analysis, this study reveals that the effective pores for $ CH_{4} $/$ N_{2} $ separation in coal-based activated carbon are those with diameters less than 1 nm, with the optimal pore size range being 0.4–0.7 nm. A novel pore structural parameter, effective pore percentage, was proposed, which exhibits a stronger correlation to separation performance and predicts the separation performance of the activated carbon more accurately than commonly used parameters. Ridge regression analysis revealed that a high proportion of effective pores (< 1 nm) generally results in higher separation efficiency, while an excessively high proportion of larger pores (> 1 nm) can diminish the separation performance of $ CH_{4} $/$ N_{2} $. This study has important implications for investigating the separation mechanism of coal-based activated carbon for $ CH_{4} $/$ N_{2} $ and for developing efficient coal-based activated carbon for purifying coalbed gas.

Ridge regression analysis revealed that a high proportion of effective pores (< 1 nm) generally results in higher separation efficiency, while an excessively high proportion of larger pores (> 1 nm) can diminish the separation performance of $ CH_{4} $/$ N_{2} $. This study has important implications for investigating the separation mechanism of coal-based activated carbon for $ CH_{4} $/$ N_{2} $ and for developing efficient coal-based activated carbon for purifying coalbed gas.

The impact of effective pore percentage on $ CH_{4} $/$ N_{2} $ separation in coal-based activated carbon |
| abstract |
The efficient separation of $ CH_{4} $/$ N_{2} $ using activated carbon depends on the strict regulation of carbon pore structure. However, the relationship between pore structure and separation performance remains inadequately explored in the literature. This study employed a sample set comprising 38 coal-based granular activated carbons with diverse pore structural parameters to investigate the impact of pore size distribution on $ CH_{4} $/$ N_{2} $ separation using advanced statistical methods. Through Pearson’s correlation analysis, this study reveals that the effective pores for $ CH_{4} $/$ N_{2} $ separation in coal-based activated carbon are those with diameters less than 1 nm, with the optimal pore size range being 0.4–0.7 nm. A novel pore structural parameter, effective pore percentage, was proposed, which exhibits a stronger correlation to separation performance and predicts the separation performance of the activated carbon more accurately than commonly used parameters. Ridge regression analysis revealed that a high proportion of effective pores (< 1 nm) generally results in higher separation efficiency, while an excessively high proportion of larger pores (> 1 nm) can diminish the separation performance of $ CH_{4} $/$ N_{2} $. This study has important implications for investigating the separation mechanism of coal-based activated carbon for $ CH_{4} $/$ N_{2} $ and for developing efficient coal-based activated carbon for purifying coalbed gas.
