ADSORBENT FOR SEPARATION AND RECOVERY OF CO, PRODUCTION THEREOF AND SEPARATION AND RECOVERY OF CO USING SAME

摘要

PURPOSE:To produce the titled adsorbent having excellent adsorption and desorption performance of CO, by contacting a solution or dispersion of a copper compound to a silica and/or alumina carrier having a specific pore size distribution and removing the solvent. CONSTITUTION:A copper compound (e.g. cuprous chloride) is dissolved or dispersed in a solvent such as water, chloroform, etc., to obtain a solution or dispersion. The solution of dispersion is optionally heated at 40-100 deg.C and sprayed to a silica and/or alumina carrier preheated at 50-150 deg.C and having particle diameter of 1-7mm and a pore size distribution characterized by the peak of pore diameter falling within 60-120Angstrom . The sprayed solution, etc., is dried in an inert gas and heated at 100-600 deg.C optionally in an inert as or reducing gas atmosphere to obtain an adsorbent for the separation and recovery of CO and containing 0.5-8m-mol/g of supported copper compound. CO is separated and recovered from a CO-containing mixed gas with the adsorbent by a pressure-swing adsorptive separation method and/or temperature-swing adsorptive separation method.
