Synthesis of "Ice Cube" Shaped Zeolite A Type and Cu Ion-Exchanged Zeolites and Study of Their CO Adsorption Performance.

In this study, zeolite type A and four Cu ion-exchanged zeolites were synthesized through cationic ion exchange process with Cu concentrations of 0.05, 0.1, 0.

CO adsorption performance of template free zeolite A and X synthesized from rice husk ash as silicon source.

In this work, zeolite NaA (RA) and NaX (RX) have been successfully synthesized using rice husk ash and it is a low cost synthesis process and it does not produce environmental hazards. Sodium silicate (SS) is extracted from rice husk ash which is an alternative silica source for zeolite synthesis. The zeolites are prepared by using a SS silica source extracted from the rice husk ash, and it has been used as an adsorbent for the CO adsorption process which may help in controlling the global warming problems.

Comparison of three different structures of zeolites prepared by template-free hydrothermal method and its CO adsorption properties.

In this study, zeolite sodalite SOD (50NaO:AlO:5SiO), zeolite LTA (2NaO:AlO:1.926SiO) and zeolite FAU (16NaO:AlO:4SiO) of different structures were synthesized successfully through simple conventional hydrothermal crystallization technique without using any template agent. Morphological analysis of three different types of zeolites revealed that the samples exhibit three different shapes such as the "Raspberry-like", "Dice" cube like and "Octahedral" shaped morphology respectively.
