摘要： A process for reacting titanium tetrachloride vapors with oxygen to produce titanium dioxide wherein the oxygen is introduced into the reactor in at least two points. The process has the ability to control properties, such as particle size, of the raw pigment produced. The temperature of the oxygen introduced to the reactor at the further inlet point is above, below, or at the same temperature of the oxygen introduced at the first inlet point. The further inlet point can be located before or after the all the titanium tetrachloride has been introduced into the reactor. The titanium tetrachloride is introduced at a relatively low temperature, below about 427° C., and the reaction temperature in the reactor is at least about 700° C. The process includes the use of an auxiliary fuel such as carbon monoxide, methane, propane, butane, pentane, hexane, benzene, xylene, toluene, or combinations thereof for increasing the temperature in the reactor. Still further, the process for producing titanium dioxide provides for the addition of aluminum chloride to the reactor. Advantageously, the process allows the pressure in the reactor to be above atmospheric pressure and range between about 0.15 MPa and 4.0 MPa above atmospheric pressure during the production of titanium dioxide. A reactor is also provided with an aluminum chloride generator for heating the titanium tetrachloride and delivering aluminum chloride to the reactor.
摘要翻译：一种使四氯化钛蒸气与氧反应产生二氧化钛的方法，其中氧气至少在两个点被引入反应器中。该方法具有控制生产的原料颜料的性质，例如粒度的能力。在另一入口点处引入反应器的氧的温度高于，低于或在与在第一入口点处引入的氧的相同温度下。进一步的入口点可以位于将四氯化钛全部引入反应器之前或之后。四氯化钛在相对较低的温度下引入，低于约427℃，反应器中的反应温度为至少约700℃。该方法包括使用辅助燃料如一氧化碳，甲烷，丙烷，丁烷，戊烷，己烷，苯，二甲苯，甲苯或其组合，以提高反应器中的温度。此外，制备二氧化钛的方法提供了向反应器中加入氯化铝。有利地，该方法允许反应器中的压力高于大气压力，并且在二氧化钛生产期间在大气压力之间的约0.15MPa和4.0MPa之间的范围。反应器还设有用于加热四氯化钛并将氯化铝输送到反应器的氯化铝发生器。
