| dc.description.abstract | Titanium dioxide (TiO2) essential for various industrial applications. Global demand for TiO2 was projected to increase annually. Thus, attention needs to be paid to ilmenite, which is abundance in nature, as the reserves of high purity source, rutile was depleting rapidly. However, Malaysian ilmenite contains high impurities. The research aims to study how varying temperatures, reaction times, and the concentration of NaCl affect the carbosulfidation process, described in the form of extent of reduction (R) and the degree of sulfidization (Xs). The morphological, and compositional properties was investigated to identify the formation of titanium oxide phases and removal of Fe. The research was conducted at different combination of parameters, done by DOE. DOE was carried out by using 2k factorial design to define the optimum parameters. Phase analysis was performed using XRD and SEM to identify surface morphology and elemental composition by EDX and XRF. From DOE results, the R was the highest at condition with 0.017 mol NaCl, 1100°C and 3 hours at 72.71 % (sample 8), while at 0.017 mol NaCl, 900 °C and 1 hours, the Xs was the highest (52.70%) in sample 5. The results showed the increase in NaCl concentration resulted in a higher R and Xs. Increasing in temperature and reaction time led to a higher R, significantly favoured the formation of titanium oxide compounds, with higher total of TiO2, and Ti6O11 phases formation in XRD result. However, the Xs decreased with longer reaction times, highlighting a limit to the sulfidation process's efficiency. XRD and SEM further confirmed the formation of key phases such as FeS2, TiO2, and Ti6O11 in cubic structure. The novelty of this research lies in its comprehensive investigation of the carbosulfidation process for extracting titanium oxides from Malaysian ilmenite while removing Fe as FeS2, by exploring the synergistic effects of both processes. | |
