Characterization and Utilization of Gunungkidul Natural Zeolite for Bioethanol Dehydration

Heat Transfer Rate of Sintered Zeolite Wick Heat Pipe

“…Zeolite is natural rock with mineral and other compounds produced from hydrothermal processes. The unique properties of zeolite that are recommended as wick materials were adsorption-desorption capability, stable in thermal and chemical properties, porous material, and environmentally friendly [5][6][7][8]. Zeolites in Indonesia are found in volcanic regions.…”

Natural Zeolits and Its Modifications with Protons and Copper As the Catalyst for Esterification of Ethanol with Acetic Acid

“…Many important organic reactions such as fat transesterification [7], bioethanol dehydration [8], and hydrocarbon cracking are processes that use zeolite as a catalyst [9].…”

The use of microwave irradiation for zeolite regeneration in a continuous ethanol dewatering process

“…In the recent years zeolite molecular sieves have been widely used for dehydration or dewatering purposes due to their unique properties to selectively adsorb water from water containing solutions, which is especially topical in a view of growing interest to bioethanol production [1][2][3][4][5]. For ethanol dewatering purposes NaA or KA zeolites are most appropriate, being synthetic zeolites, since they have small aperture diameters (4 and 3 Å respectively), therefore organic molecules having two or more C atoms cannot penetrate inside the zeolite pores and remain in a liquid phase, while smaller molecules like water ones are effectively absorbed and retained by zeolites.…”
