Abstract
ESTA INVENCION SE REFIERE A UN METODO DE TRATAMIENTO DE UN TIPO DE CARBON BLANCO (DIOXIDO DE SILICIO NO PURO QUE CONTIENE MAS DE UN 93% DE SIO{SUB,2}). SEGUN ESTE METODO SE AÑADE UNA CANTIDAD ADECUADA DE AGUA DE MAR A UN SILICATO SODICO Y SE AGITA SUFICIENTEMENTE A TEMPERATURA NORMAL Y PRESION NORMAL. ESTO HARA QUE EL SILICATO SODICO SE CONVIERTA EN DIOXIDO DE SILICIO, MIENTRAS QUE EL OXIDO SODICO SE DISOLVERA EN EL AGUA DE MAR. EL DIOXIDO DE SILICIO SE PUEDE SEPARAR ANTES DE TRATARLO PARA OBTENER UN PRODUCTO DE CARBON BLANCO EN POLVO. ESTA INVENCION TIENE LAS SIGUIENTES VENTAJAS: SE PUEDE PRODUCIR GRAN CANTIDAD DE CARBON BLANCO DE MANERA ECONOMICA; EL LIQUIDO DE DESECHO DESCARGADO NO CONTAMINA EL AMBIENTE; Y EL CARBON BLANCO PRODUCIDO SEGUN ESTE METODO ES ALCALESCENTE, LO QUE PUEDE MEJORAR LA CALIDAD DE SUS PRODUCTOS DERIVADOS.
