Mark W. Ackley, Salil U. Rege, Himanshu Saxena Praxair, Inc., 175 East Park Drive, Tonawanda, NY 14151, USA Received 22 July 2002; received in revised form 21 October 2002; accepted 22 October 2002 Abstract There are many natural zeolites of which a small number including clinoptilolite, chabazite, mordenite, erionite, ferrierite and phillipsite offer the greatest promise for gas separation. Patents and other literature have been surveyed to identify the bulk separation and purification processes for which these zeolites have potential. The abundance and low raw material cost of natural zeolites have rarely offset such disadvantages as variable composition, low purity ... Διαβάστε περισσότερα
