Abstract

<p>LA INVENCIÓN ANTERIOR SE RELACIONA CON UN PROCESO DE CALCINACIÓN DE PARTÍCULAS DE MINERAL QUE CONTIENEN CARBONO Y/O AZUFRE, DONDE LAS PARTÍCULAS SE ALIMENTAN AL REACTOR PARA SU CALCINACIÓN. SE INTRODUCE UN GAS QUE CONTIENE OXÍGENO, DONDE LAS PARTÍCULAS SE CALCINAN EN UN LECHO FLUIDIZADO A UNA TEMPERATURA DE 500 A 1.000 °C DURANTE AL MENOS 10 SEGUNDOS Y DONDE LAS PARTÍCULAS CALCINADAS SE EXTRAEN DEL REACTOR. LAS PARTÍCULAS TIENEN UN CONTENIDO MÁXIMO DE AGUA DE 2 % EN PESO Y SE INYECTAN NEUMÁTICAMENTE AL LECHO FLUIDIZADO.</p>
