  • Patent number: 12228490
    Abstract: Disclosed is a screening method for selecting an adsorbent for use in environment-friendly gas-insulated equipment which contains an environment-friendly gas functioning as an insulating medium inside the equipment, the adsorbent to adsorb unwanted decomposed gas that is produced from decomposition of the environmental-friendly gas, the method steps include: establishing screening sets, performing pre-experiment adsorption experiment screening, standard gas adsorption experiment screening, and mixed gas adsorption experiment screening, establishing mapping relationship between a decomposed gas type set and a third adsorbent type set under different working conditions, and selecting an adsorbent combination mode suitable for a working condition type and a mixed gas composition mode based on the mapping relationship.
