Abstract

SE TRATA DE UN PROCEDIMIENTO Y DE UN DISPOSITIVO QUE APLICA UN PROCESO DE FORMACION DE CALCIO A PARTIR DE CARBONATO DE CALCIO PULVERULENTO, SEGUN EL CUAL SE REALIZA EN UN REACTOR UN BAÑO INICIAL DE OXIDO DE CALCIO PULVERULENTO EN LECHO FLUIDIZADO QUE SE CALIENTA ELECTRICAMENTE A UNA TEMPERATURA SUPERIOR A 900 C, Y DESPUES SE INTRODUCE EN CONTINUO DICHO CARBONATO DE CALCIO PULVERULENTO EN EL BAÑO MANTENIENDO LA TEMPERATURA DEL BAÑO SIEMPRE SUPERIOR A 860 C POR CALENTAMIENTO ELECTRICO, PARA DISOCIAR DICHO CARBONATO DE CALCIO EN OXIDO DE CALCIO Y EN ANHIDRIDO CARBONICO.
