PRODUCTION OF ADSORBENT FOR GAS CONTAINING HYDROGEN SULFIDE

摘要

PURPOSE:To adsorb and remove a sulfur compd. by using an adsorbent obtd. by soaking a silica-alumina molded body contg. zeolite in an iron ammonium oxalate soln. and by drying and baking the molded body. CONSTITUTION:A silica-alumina molded body contg. zeolite such as zeolite A or mordenite is baked at about 700 deg.C to provide thermal stability. The molded body is successively soaked in ferric nitrate and iron ammonium oxalate solns. and dried. After the soaking and drying operation is repeated 2-3 times, the molded body is baked to obtain an adsorbent having superior formability and high utility.
