| 摘 要： | 以镁钙质量分数大于2.5%的高钛渣为原料,采用复合流化床制备四氯化钛新工艺进行中试试验。对试验中氯气流量、流态化温度等参数进行了讨论,并对反应产物的形貌进行了分析,同时计算了反应效率。中试结果表明,TiO2的转化率达到90%。通过检测发现收尘渣表面富集MgCl2和CaCl2,而流化床中未出现粘结,说明该流化床具有一定的抗粘结能力。

| Abstract: | A new process of TiCl4 preparation in a combined fluidized bed was researched on pilot plant scale.The titanium slag with high content of MgO and CaO(>2.5%) was used as the feedback.Several experimental parameters such as chlorine flow,reaction temperature were discussed and the morphology of reaction product was analyzed.The conversion of TiO2 was up to 90%.It is found that the anti-agglomeration ability of the combined fluidized bed is obvious because of the accumulation of MgCl2 and CaCl2 on the surface ... |
