摘要：
The Y-type Na zeolite was modified with Mn, Co, Ni and Cu nitrates in aq. solns. at 90 degrees C for 2 h. The modified zeolites were used as adsorbents for removing odourous BuNH(2), BuSH and thiophene from N(2) stream at 150 degrees C in 10 cycles. The adsorption of BuNH(2) was the most efficient on NaNiY and NaCoY zeolites while that of BuSH and thiophene on NaCuY zeolite. The adsorption of BuNH(2) was the most stable, while of thiophene the less one. The zeolites were regenerated at elevated temp.
