Zeolite filter material

The zeolite is a kind of substance of polarity and the absorptive agent with strong polarity. It has strong absorptive effects to the polar molecules and organic substances of unsaturated molecules, such as halohydrocarbon, and it also has higher advantages on selective absorption to the non-polarity molecules with extremely large polarity rate. There are two kinds of zeolite filtering material currently: naturally volatilizing zeolite filtering material and activated zeolite filtering material.

The technical index

Absorptive performances

Surface area rate (m2/g): 122-355; the absorptive capacity of sulfur dioxide is 47-58.2 ml/g.

The performance of positive ion exchanging

NH4+exchanging capacity (mmol/100g)

Maximum minimum, common or average value: 150 109 127.58

K + exchanging capacity (mg/100g)

Maximum, common or average value: 18.75 13.19


The catalyzing performance

The zeolite has the large surface area ratio, as well as good crystallization performance. The testing of catalyzing and disproportionation with methylbenzene has proved that, it is feasible to use the remodeled zeolite to manufacture the methylbenzene catalyst, and it has higher catalyzing activation to the isomerized xylene.

The performance of acidity and heat endurance


The performance of acidity endurance: when the zeolite is kept under 90 Celsius degree for 4 hours and in the hydrochloride acid with the concentration of 1N, it is not damaged; when the concentration of hydrochloride acid is 2N, part of the zeolite will be damaged.


The performance of heat endurance: The lattice varies a little under 250 Celsius degree, it will be basically damaged under 500 Celsius degree, and it will be totally damaged under 750 Celsius degree.

The experiments have proved that the temperature for damaging lattice is 250-500 Celsius degree, and the burning time is 4 hours.
