“Filtering Carbon dioxide trough Molecular absorption of Liquefied Zeolite”
Problem and Its Settings • Introduction As of October 2010Uis at a concentration of 388 ppm by volum, Atmospheric concentrations of carbon dioxide fluctuate slightly with the change of the seasons, driven primarily by seasonal plant growth in the Northern Hemispher.Concentrations of carbon dioxide fall during the northern spring and summer as plants consume the gas, and rise during the northern autumn and winter as plants go dormant, die and decay. Taking all this into account, the concentration of CO2 grew by about 2 ppm in 2009. Carbon dioxide is a greenhouse as it transmits visible light but absorbs strongly in the infrared and near-infrared. As the chemical most stable non-condensing greenhouse gas, it acts as critical knob. It is composed of two oxygen atoms covalently bonded to single carbon atom. Carbon dioxide in higher concentrations: 1% (10,000 ppm) will make some people feel drowsy.[5] Concentrations of 7% to 10% cause dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour. And it has a great part in forming Global Warming. And changes our climate unaccordingly. Because of the effects of the substance, the researcher got an idea in using a particular stone to filter and reduced the excess presence of carbon in the air. That’s why the researcher initiate to study about this: Zeolites are microporous crystalline solids with well-defined structures. Generally they contain silicon, aluminium and oxygen in their framework and cations, water and/or other molecules wthin their pores. Many occur naturally as minerals, and are extensively mined in many parts of the world. Others are synthetic, and are made commercially for specific uses, or produced by research scientists trying to understand more about their chemistry.

Review of Related Literature • Carbon dioxide Carbon dioxide is colorless. At low concentrations, the gas is odorless. At higher concentrations it has a sharp, acidic odor. It can cause asphyxiation and irritation. When inhaled at concentrations much higher than usual atmospheric levels, it can produce a sour taste in the mouth and a stinging sensation in the nose and throat. These effects result from the gas dissolving in the mucous membranes and saliva,forming a weak solution of carbonic acid. This sensation can also occur during an attempt to stifle a burp after drinking a carbonated beverage. Amounts above 5,000 ppm are considered very unhealthy, and those above about 50,000 ppm (equal to 5% by volume) are considered dangerous to animal life. Above −78.51° C or −109.3° F carbon dioxide changes directly from a solid phase to a gaseous phase through sublimation, or from gaseous to solid through deposition. Solid carbon dioxide is commonly called “dry ice", a generick trademark. It was first observed in 1825 by the French chemist Charles Thilorier.
Uses Carbon dioxide is used by the food industry, the oil industry, and the chemical industry.[14] It is used in many consumer products that require pressurized gas because it is inexpensive and nonflammable, and because it undergoes a phase transition from gas to liquid at room temperature at an attainable pressure of approximately 60 bar (870 psi, 59 atm), allowing far more carbon dioxide to fit in a given container than otherwise would. Life jackets often contain canisters of pressured carbon dioxide for quick inflation. Aluminum capsules of CO2 are also sold as supplies of compressed gas for airguns, paintball markers, inflating bicycle tires, and for making carbonated water. Rapid vaporization of liquid carbon dioxide is used for blasting in coal mines. High concentrations of carbon dioxide can also be used to kill pests.
Filtration Amine+H2O->(Amine-H2O) and then ( Amine H2O)+ CO2->(Amine-H2CO3)
Reactivation (Amine-H2CO3) + heat-> Amine = H2O = CO2 The filtration material is nonpoisonous and durable. It cn be reactivated more than 5000 times, which corresponds to some 15 years use. The Uniqfrest first-stage filter should be replaced every six months, and the HEPA filter should be replaced every five years.
Zeolites Zeolites have the ability to act as catalysts for chemical reactions which take place within the internal cavities. An important class of reactions is that catalysed by hydrogen-exchanged zeolites, whose framework-bound protons give rise to very high acidity. This is exploited in many organic reactions, including crude oil cracking, isomerisation and fuel synthesis. Zeolites can also serve as oxidation or reduction catalysts, often after metals have been introduced into the framework. Examples are the use of titanium ZSM-5 in the production of caprolactam, and copper zeolites in NOx decomposition. Because of their unique porous properties, zeolites are used in a variety of applications with a global market of several milliion tonnes per annum. In the western world, major uses are in petrochemical cracking, ion-exchange (water softening and purification), and in the separation and removal of gases and solvents. Other applications are in agriculture, animal husbandry and construction. They are often also referred to as molecular sieves.
Uses It Helps by decreasing the temperature level during manufacture and laying t asphalt concentrate, resulting in lower consumption of fossils fuels, thus releasing less carbon dioxide, aerosols and vapors. In other country they usede zeolites as one of the ingredients detergent. And even the United States used zeolite –based oxygen concentrator systems are wildly to produced madical madical-grade oxygen. It is used as molecular sieve to create purified oxygen from air using its ability to trap impurities in a process involving the absorption of nitrogen leaving highly purified oxygen and up to 5% axon.
Ion Exchange • The loosely-bound nature of extra-framework metal ions (such as in zeoliteNaA, right) means that they are often readily exchanged for other types of metal when in aqueous solution. This is exploited in a major way in water softening, where alkali metals such as sodium or potassium prefer to exchange out of the zeolite, being replaced by the "hard" calcium and magnesium ions from the water. Many commercial washing powders thus contain substantial amounts of zeolite. Commercial waste water containing heavy metals, and nuclear effluents containing radioactive isotopes can also be cleaned up using such zeolites.

Liquefied Zeolite • Liquid stone is basically a colloidal suspension of micronized powdered zeolite- a hydrated aluminisilicateminiral- which has undergo a purification and activation manufacturing process. 4,5 di-cyclo, disilico, dimagnesium, dialumino, oxyo, trihydrate — "liquid zeolite" for short! This diagram shows the zeolite's honeycomb or cage-like structure which allows it to trap toxins.
