Investigation of TiO2 AlF3 and V2O5 on Sintered Mullite Porous Microstructure using SEM and TGA 2019-01-1407

The exhaust emissions from diesel combustion are the sources of particulate matter emitted to the atmosphere, which are components of air pollution that implicated in human health such as lung cancer. At present the diesel particulate filter can remove PM from the exhaust gas before emitted to the atmosphere. This research is investigating morphology and nanostructure of acicular mullite to develop the fabrication process filter in order to study particulate matters trapping and oxidation mechanisms. This research aims to investigate the porosity, pore size distribution and morphology of acicular mullite porous media. We used two main substance to study the structure of diesel particulate filter; Aluminium oxide (Al2O3) and Silicon dioxide (SiO2). These are mainly in the conventional DPF. The variable substance are Titanium dioxide (TiO2), Aluminium fluoride (AlF3) and Vanadium oxide (V2O5) which added to investigate the acicular structure. The sintering process at sintering holding times 1 hours and sintering temperatures furnace of 1300 oC. Moreover, a constant amount of carbon black were used to open the porosity of DPF. The images of Mullite Porous Microstructure surface were practically investigated using scanning electron microscopy (SEM). The image processing of two-color image was done by “Image J” program for pore size distribution. The oxidation behavior were investigated by using Thermo-Gravimetric Analysis (TGA) for analysis oxidation kinetics. Diesel PMs and carbon black were used with Sintered Mullite by TGA isothermal method. The result of this research can be good information about effect of Titanium dioxide (TiO2), Aluminium fluoride (AlF3) and Vanadium oxide (V2O5) to Sintered Mullite Porous Microstructure. And the research results also can be used for the development of advanced academic and the practical in industry.
