Abstract
The breakthrough curve was obtained to evaluate separation efficiency of clinoptilolite as an methane/nitrogen separation adsorbent. The Ca-exchanged clinoptilolite showed improved separation efficiency. The nitrogen adsorption capacity of Ca-clinoptilolite was increased with decreasing temperature. The temperature was decreased from 293K to 253K(feed gas flow rate : 670ml/min, pressure : 333kPa). The adsorption capacity is increased with increasing pressure. The pressure was increased from 333kPa to 700kPa(feed gas flow rate : 670ml/min, temperature : 253K, 293K).
메탄/질소 분리용 흡착제로의 성능평가를 위하여 천연 제올라이트의 일종인 clinoptilolite 로 파과실험을 수행하였다. 분리성능을 향상시키기 위해 Ca으로 이온교환한 clinoptilolite에 대하여
