Abstract
The manufacture of titanium dioxide by oxidation of titanium tetrachloride in a plug flow reactor, wherein the titanium tetrachloride is introduced into the reactor in at least two stages and is used exclusively in liquid form. The total quantity of liquid TiClused is split up in several stages. A small quantity is added in the first stage in order to start combustion despite using the liquid phase. In the first phase, the activation energy required is provided solely via the preheated oxygen. In all other stages, the activation energy is provided by the preheated oxygen and the reaction enthalpy of TiCloxidation released in the upstream stages.
