Use of zeolites

Adsorbents and desiccants
Catalyst
Detergent
Other uses (wastewater treatment, soil conditioners, feed additives)
Zeolite is a new material, is widely used in industry, agriculture, defense and other sectors, and its use are continuing to explore. Zeolite is used as ion exchangers, adsorption separation, drying agents, catalysts, cement admixture. In the petroleum, chemical industry, as petroleum refining catalytic cracking, hydrocracking and petroleum chemical isomerization, reforming, alkylation, disproportionation; gas and liquid purification, separation and storage agent; water softening, water desalination agent; special desiccant (dry air, nitrogen, hydrocarbons, etc.). In light industry for the paper, synthetic rubber, plastics, resins, fillers and coating quality color. In defense, space technology, ultra-high vacuum technology, the development of energy, electronics, etc., used as a separating agent and desiccant adsorption. In the building materials industry, as active hydraulic cement admixture, firing artificial lightweight aggregate, produce lightweight high-strength sheet metal and bricks. In agriculture as a soil conditioner, can play a fertilizer, water, prevent pest effect. In the livestock industry, as feed (pigs, chickens) additives and deodorants, can promote animal growth, improve chick survival. In terms of environmental protection to deal with waste gas, waste water, removal or recycling of metal ions, removal of radioactive contaminants in wastewater effluent from the wastewater.
activated zeolite powders in medicine for the determination of blood and urinary nitrogen content. Zeolite was also developed as a health supplies for anti-aging, remove heavy metals accumulated in the body.
In the production of zeolite commonly used in sugar refining.
New wall materials (aerated concrete blocks) materials
With the solid clay brick gradually leave the stage, the proportion of new wall materials application has now reached 80% of the wall materials production enterprises to gangue, fly ash, ceramic, slag, light industrial waste, heavy construction waste and zeolite based materials, and actively develop new wall materials.
Distillation or heating in a chemical experiment which used to prevent bumping, because the structure of the synthetic zeolite powder which have a large number of small holes, can be used as the bubble condensation nuclei, the reaction solution stable boiling. Available crack to the grain size of unglazed tiles instead.
