Description

ABSTRACT:
Clinoptilolites, including both natural and synthetic clinoptilolites which have been ion-exchanged with metal cations such as lithium, sodium, potassium, calcium, magnesium, barium, strontiun, zinc, copper, cobalt, iron and manganese, are useful for the removal of traces of ammonia from streams of hydrocarbons having kinetic diameters of not more than about 5 .ANG.. This invention relates to the process of producing the modified clinoptilolite adsorbent.
