Abstract

PROCEDIMIENTO Y REACTOR (10) QUE PERMITEN HACER REACCIONAR VAPORES DE TETRACLORURO DE TITANIO CON OXIGENO PARA PRODUCIR DIOXIDO DE TITANIO. DE ACUERDO CON EL PROCEDIMIENTO, SE INTRODUCE OXIGENO EN EL REACTOR POR AL MENOS DOS PUNTOS, UN PRIMER CONJUNTO DE INTRODUCCION (12) DEL GAS OXIDANTE Y UN SEGUNDO CONJUNTO DE INTRODUCCION (26) DEL GAS OXIDANTE. LA TEMPERATURA DEL OXIGENO INTRODUCIDO EN EL REACTOR POR EL SEGUNDO CONJUNTO DE INTRODUCCION (26) DEL GAS OXIDANTE, ES SUPERIOR, INFERIOR O IGUAL A LA DEL OXIGENO INTRODUCIDO POR EL PRIMER CONJUNTO DE INTRODUCCION (12). EL SEGUNDO CONJUNTO DE INTRODUCCION (26) DEL GAS OXIDANTE PUEDE ESTAR SITUADO ANTES O DESPUES DE LA INTRODUCCION DE LA TOTALIDAD DEL TETRACLORURO DE TITANIO EN EL REACTOR (10). SE INTRODUCE EL TETRACLORURO DE TITANIO EN EL REACTOR (10) A UNA TEMPERATURA RELATIVAMENTE BAJA, INFERIOR A 427 C APROXIMADAMENTE, POR MEDIO DE UN PRIMER CONJUNTO DE INTRODUCCION (20) DE TETRACLORURO DE TITANIO. LA TEMPERATURA DE REACCION EN EL REACTOR ES DE AL MENOS 700 C APROXIMADAMENTE. EVENTUALMENTE PUEDE INTRODUCIRSE UNA SEGUNDA CANTIDAD DE TETRACLORURO DE TITANIO EN EL REACTOR (10) POR MEDIO DE UN SEGUNDO CONJUNTO DE INTRODUCCION (34) DE TETRACLORURO DE TITANIO.
