Con Decon Process : It is a dilute chemical decontamination process that avoids the draining or flushing of the system to be decontaminated. It is also not necessary to defuel the reactor due to decontamination process. This is thus a simplified process which results in cleaning of the fuel at the same time, adding a huge advantage of removing a significant amount of activated corrosion product which if allowed to remain would eventually dissolve and redeposit out-core, thus partially negating the effects of the decontamination. Figure 1- Con Decon Process 4 The following equations show some of the chemical reactions involved in magnetite dissolution. The study was carried out by making an oxide covered disk the working electrode in an
With a smaller need of gasoline, the mining of fossil fuels could be reduced thus preventing from the nonstop execution of our minerals. Besides, hybrid cars also can reduce current pollution as they emit less harmful and toxic gaseous from the exhaust. Miller(2004) claimed that hybrid cars also produce low sound which means less noise compared to the regular combustion engine cars. Engineers use electrical motors as they meant to work with a low sound. Moreover, in terms of energy, hybrid cars have higher efficiency compared to conventional and full electric cars as it uses kinetic energy from braking to form electric energy then, charging the battery simultaneously.
Adsorption is one of the major process used for the removal of Cr(VI) worldwide because it is inexpensive, widely applicable, efficient and creates little amount of sludge(Kannan and Rengasamy, 2005). Chromium can be removed using adsorbents of natural as well as chemical origin. However, these bio-adsorbents have various disadvantages like waste may itself contain various toxicants and subsequently increase the organic content of water. Studies have showed adsorption capacities and applicability for some low-cost materials, among others like alluminium oxide, chitosan, bentonite, saw dust and waste slurry (Dubey and Gopal, 2007). Activated carbon is an effective inexpensive adsorbent which has use in various industries to purify water (D Mohan and Chander, 2001; Yoshihara et al.,2007; Yin et al., 2007).
Future possibilities and environment benefits, there’s a study that it lessen the air pollution by using it. Abundant domestic production, increased resale value and more affordable maintenance. As evidenced in the Environment Protection Agency, natural gas as the cleanest fossil fuel was used in many ways to help reduce the emissions of pollutants into the environment. Burning natural gas than other fossil fuels emits fewer harmful pollutants and increase the reliance on potentially reduces emission of those many harmful pollutants. The use of natural gas does not significantly contribute in the formation of the smog as it emits lower nitrogen oxide and doesn’t have particulate matters.
Oxygenated compounds Oxygenated fuel is a compound that has a chemical compound containing oxygen. It helps to burn fuel more efficiently so reduces some type of atmospheric pollution. It reduces carbon mono oxide emission and smog formation. Oxygenated fuel allows fuel in vehicles to burn more efficiently because more of fuel is burning so there are fewer chemical pollutants released. Oxygenated fuel also help to cut down renewable fossil fuel consumption.
This happens because enzymes lower the activation energy, as they provide an alternative reaction pathway. The decrease in the energy level aids in making the process happen faster (Jae In Lee, 2011) A catalase is an enzyme, which is found in all living organisms. This enzyme helps to convert hydrogen peroxide into oxygen and water. Chemical actions that happen within the cell produces hydrogen peroxide, which is poisonous and therefore can kill the organism. As a result the presence of the enzyme catalase in the cell helps to quickly convert this toxic substrate into safer products of water and oxygen (All Science Fair Projects, 2004).
The extracted organic layer was steam bathed to vaporize light petroleum which has low boiling point at 30-40˚C. Chromic acid is a more commonly used reagent for the oxidation of alcohols, it is a suspected carcinogen and generates hazardous waste. In green chemistry, innocuous chemical such as hypochlorous acid, HOCl will be used in oxidation, as to reduce the harmful waste. Green chemistry is the name given to modifications implemented in chemical manufacturing processes that ensure a safer and cleaner
(14) A catalyst is a substance that contributes to the reaction, lowering the energy needed for a collision to occur. It does this without undergoing a chemical change itself, and without changing the properties of the reactants. (15) Catalysts weaken the bonds of the molecules, meaning that they provide an alternative reaction pathway to the reaction product, making it simpler for collisions to occur. Hydrogen peroxide is not a very stable compound, so, it is always decomposing to water and oxygen. Even in normal conditions, air can weaken or even break down the bonds in this substance, making the compound unstable.
In order to minimize the cost of purification process, heterogeneous solid catalyst such as metal oxides, zeolites, hydroalcites, and γ-alumina have been used recently. Some of these catalysts are promising but some still have low performance compared to homogeneous catalyst in term of FAME yield and activity. The advantages of using heterogeneous are these catalysts can be separated easily from the reaction mixture and can be reuse. Most of these catalysts are alkali or alkaline oxides supported on materials with a large surface and they are more active than solid acid catalysts (Thanh, Okitsu, Boi, & Maeda,
“By saving energy in industrial production through recycling, the greenhouse gas emissions from factories and industrial plants are lessened and the use of fuels that emit harmful gases during production is also minimized. Recycling non-biodegradable waste (rather than burning it) will contribute a lot to help reduce air pollution and greenhouse gases that depletes the ozone layer,” stated in the article, Benefits of Recycling (2015). One way to eliminate garbage is through burning, but some people have no idea of what are the bad effects of it. Pollution- free atmosphere and environment will result to a better living. Lastly, mandatory recycling helps to save money that is spent for disposing trash and other waste materials of a business.
