There are actually many ways to reduce the emission of CO2 such as using public transport, heating up fewer fossil fuels and also not to forget the implement of more renewable energy technologies. Chemical Looping Combustion (CLC) is considered as one the most crucial strategy that meets the reduction of CO2 emission. This technology considered as one the best alternatives ways to reduce or to minimize the carbon dioxide release who are still burning the fossil fuels. This technology can be a vital technology for the industrial that have been reliant on fossil fuels. Chemical Looping Combustion (CLC) is a technology that have basically two reactors, both of this reactors are called the Air Reactor (AR) and the Fuel Reactor (FR) which there is a oxide of metal is feeding the oxygen for assisting the fuel reactor in combustion. After that, the thinned oxide metal is transferred to the air rector to be re- oxidized before the oxide metal is dispatched to the fuel reactor and the cycle completes. To gain an effective process in the performance of the CLC, the most crucial element that we need to target is on picking the best oxygen carrier. For this research, Fe2O3-Bauxite Waste has been synthesized by the method of dry impregnation and it is worn as the oxygen carrier in this project. The main purpose of this research is varying the temperatures and examine the variation of the geometry, morphology, element compositions, crystallite size and also examine the surface area in Fe2O3-Bauxite Waste. In accordance with the results from geometry and morphological tests, what can be observed is the structure on the bauxite waste were the changes of the forms from powder to solid form as the temperature is increased. Furthermore, the grain size of the powder likewise expanded as the sintering temperature raised. The cause of this action is kapected to the presence of agglomeration as the temperature raised, it is because the particles will adhere to one another to shape a bigger element (agglomerates) in comparison when it is varied at a lower temperature compare to a higher temperature. In reference to the element composition tests, the results shows there is a few existence of elements in the specimen which they are Ferum (Fe), Oxygen (O), Aluminium (AI), Silica (Si), Carbon (CaCO3), and Titanium (Ti). The presence of Aluminium (A1) in the sample gives a positive feedback because it gives the element more strength as what can be seen based on the results the higher the temperature the higher the value of the Aluminium (A1) it gives more strength to the material as the temperature increases. Other than that, the presence of Titanium in the element gives an edge for the sample because it shows that it can gives an excellent responsiveness as an oxygen carrier for the process of CLC. It is normally can function for a lengthy operational time, most importantly it is structurally stable. As for the composition and crystallite size analysis, from the results the specimen shows there is only Fe2O3 and A1203 that contains in the specimen. From the observation of crystallite size the Fe2O3-Bauxite Waste has increment as for the temperature of 700°C and 900oC from 52 nm to 74 nm. However, for the temperature from 900°C to 1000°C the crystallite size from the Fe2O3-Bauxite Waste shows there is an increment in size from 74 nm to 88 nm. As from the results, the crystallite size has slight decrement in size when it is heated at 1000°C to 1200°C which is 88 nm to 78 nm in size. The reason of the diminishing of the crystallite size of the specimen between temperatures 1000°C to 1200°C is because of the phase transformation occurrence. Last but not least, the main objectives of this research is to characterize the elemental and morphological of bauxite waste with Fe2O3 at different temperature and to synthesize bauxite waste with Fe2O3 by targeting more environmentally friendly material by using the method of dry impregnation for chemical looping combustion has been achieved. This proves that bauxite waste can be a potential oxygen carrier for the technology of chemical looping combustion with the support of Fe203. 2024-08-26T04:12:18Z 2024-08-26T04:12:18Z 2019 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/33320 en application/pdf
