Zusammenfassung: | In order to solve the agglomeration problem in TiCl4 preparation, a new test in a multistage series combined fluidized bed was studied on a pilot scale. The pilot plant can make full use of titanium slag with a high content of MgO and CaO as the feedstock. Several experimental parameters such as chlorine flow and reaction temperature were discussed and the morphology and components of reaction product were analyzed. According to the results, the conversion rate of TiO2 is up to 90%. It is found that the combined fluidized bed has good anti-agglomeration ability because the accumulation of MgCl2 and CaCl2 on the surface of unreacted slag was carried out of the reactor. |
