Natural vs. Synthetic Zeolites [PDF]
Crystals, 2020 This brief review article describes the structure, properties and applications of natural and synthetic zeolites, with particular emphasis on zeolites obtained from natural or waste materials. Certainly, such short work does not exhaust the complexity of the problem, but it sheds light on some outstanding issues on this subject.

The Use of Natural Zeolite as A Catalyst for Esterification Reaction Between Glycerol and Oleic Acid
Reaktor, 2019 Natural zeolite in Indonesia generally divided into 2 types, which are mordernite and clinoptilolite. As far the use of zeolites is very limited. This experiment tries to use both types of natural zeolites to find out its work.
