Abstract

PROCESO PARA LA PREPARACION DE 2,2'' DE NIQUEL QUE COMPRENDE UN CANTIDAD SIGNIFICATIVA DE COMBINADO DE NIQUEL ELEMENTAL EN UN SOPORTE ADECUADO. EN UNA INCORPORACION LA REACCION DE ACOPLAMIENTO TIENE LUGAR EN VARIOS DISEÑOS DE REACTOR A UNA TEMPERATURA DE ENTRE 200-400 (GRADOS) C Y A UNA PRESION SUFICIENTE PARA MANTENER AL MENOS PARTE DE LA BASE EN UN ESTADO LIQUIDO DURANTE LA REACCION. EN OTRAS INCORPORACIONES PREFERIDAS, LOS PROCESOS DE PREPARACION DE 2,2'' SE LLEVAN A CABO A UNA TEMPERATURA DE ENTRE 175-240 (GRADOS) C. ESTOS ULTIMOS PROCESOS EXIGEN QUE EL NIQUEL POSEA UNA AREA SUPERFICIAL DE NIQUEL ESPECIFICA ALTA.
