摘要
FIELD: sorbents. SUBSTANCE: x-type zeolites in which cations compensate negative charge contains ca.95 to 50% of lithium ions, 4 to 50% of one or more aluminum, cerium, lanthanum, and lanthanoid mixture, and 0 to 15% of other ions. Zeolites basically adsorb nitrogen from gas mixture. Different versions of two-step ion-exchange zeolite production method are proposed. EFFECT: enhanced efficiency of nitrogen isolation on zeolites with elevated heat resistance. 23 cl, 8 tbl, 6 ex
