Pressure swing adsorption for CO 2 /N 2 and CO 2 /CH 4 separation: Comparison between activated carbons and zeolites performances

Preparation and CO2 adsorption properties of porous carbon from camphor leaves by hydrothermal carbonization and sequential potassium hydroxide activation

“…Currently, capturing CO 2 using various porous materials has attracted increasing attention, including materials such as zeolites, mesoporous silica, metal-organic frameworks, molecular sieves and porous carbon, because of their abundant pore structures and high surface area. [1][2][3][4] Among these materials, porous carbons have the greatest potential for application because they are derived from a large variety of low-cost resources and have a highly developed porous structure, abundant functional groups, hydrophobicity and high availability. [5][6][7] Porous carbons are oen derived from various biomasses by thermal pyrolysis, chemical activation or hydrothermal carbonization (HTC), followed by carbonization or chemical activation.…”

Assessment of Calorific Value of Biogas after Carbon Dioxide Adsorption Process Using Natural Zeolite and Biochar

“…The second highest was the biogas that had been through CO 2 adsorption using the combination of natural zeolite and biogas sludge based biochar (Z-BS) of 5,12%. Reference [18] reported that specific surface area of adsorbent had important role in CO 2 adsorption under a gas pressure range of 5-8 bar. The energy of biogas can be converted to energy for cooking through combustion process.…”

Low-Cost Syngas Shifting for Remote Gasifiers: Combination of CO2 Adsorption and Catalyst Addition in a Novel and Simplified Packed Structure

“…This material was selected based on its effectiveness and stability [32,33]. Additionally, zeolite was chosen as the support material due to its properties as a molecular sieve for CO 2 adsorption [34,35]. The gasifier is equipped with a control system that allows the CO/CO 2 ratio to be maintained during operation.…”
