LARGE SCALE CO SEPARATION BY VPSA USING CUCL/ZEOLITE ADSORBENT

摘要：

Based on the principles that cuprous ions can form complex with carbon monoxide and salts can spontaneously disperse onto the surface of supports as a monolayer, a highly efficient CO adsorbent, CuCl/Zeoilte, has been made by heating a mixture of CuCl and a zeolite at a suitable temperature to disperse the CuCl onto the surface of the zeolite.This adsorbent has high CO adsorption capacity (＞50ml/g at 1 atm. and ambient temperature) and high CO selectivity over H2, N2, CH4 and CO. Using this adsorbent in a VPSA process, a large scale plant has been designed and built in China for separation of CO from syngas. The feed gas contains about CO 30％, H2 41％, N2 17％,CO2 8％, CH4 2％, O2 0.4％,and saturated water. The plant can produce carbon monoxide 1700m3 per hour with purity ＞99％ and recover ＞85％.
