Abstract
<PICT:0971458/C1/1> Metal halides are prepared by forming a bed of pellets consisting of a mixture of particles of a metal oxide and of carbon in stoichiometric proportions in accordance with the equation MO2+2C+2X2=MX4+2CO where M represents a metal and X represents a halogen, the major proportion by weight of the pellets having a major dimension in the range of 1 mm. to 11 mm., maintaining a reaction zone in the bed at a halogenating temperature, passing a halogenating gas into the reaction zone under substantially static bed conditions, and withdrawing gaseous reaction products upwardly from the reaction zone to effect heat transfer between the reaction products and the pellets in the upper part of the bed. The reaction is thermally autogeneous. The process is illustrated by reference to the chlorination of hafnium and zirconium but the production of the chlorides of titanium, chromium, aluminium, silicon, niobium, tantalum, beryllium, boron, tin and uranium is also referred to. Elemental chlorine is the preferred source of chlorine although other sources, for example, CCl4, COCl2, S2Cl2 and SOCl2, may be used. As shown in Fig. 2, chlorine, admitted through line 22, passes upwardly through a cooled lower zone of pellets 38 to a preheated reaction zone 37. The chlorine reacts with the pellets in the reaction zone and the gaseous reaction products pass upwardly through the chlorinator in heat exchange with the pellets in zone 40. As the pellets in the reaction zone are consumed they are replaced by the preheated pellets in zone 40.
