CO2 separation agent and method for selective separation of CO2

摘要

PPROBLEM TO BE SOLVED: To provide a COSB2/SBseparating agent capable of selectively separating COSB2/SBhigh-efficiently and economically from high pressure gas containing high-pressure COSB2/SBand a method for selectively separating COSB2/SBhigh-efficiently and economically from high pressure gas containing high-pressure COSB2/SB. PSOLUTION: The COSB2/SBseparating agent for selectively separating COSB2/SBfrom high pressure gas containing COSB2/SBcomprises pure silica zeolite. The method for selectively separating COSB2/SBcomprises the steps of: contacting high pressure gas containing COSB2/SBwith pure silica zeolite to adsorb COSB2/SBon pure silica zeolite; and desorbing the adsorbed COSB2/SB.
