Using zeolite The required amount is simply placed in the filter just before the water is returned to the pond or tank.
An example of this is the K + form zeolite Y catalyzed cracking of hexane at 500 C [4 ].
The zeolite catalyst has sites which can remove a hydrogen from an alkane together with the two electrons which bound it to the carbon.
Photographs of the zeolite minerals found at some of these sites can be viewed on the Skye mineral gallery pages.
Most theoretical calculations have been carried out on representative portions of the zeolite framework called clusters.
