Abstract
"PROCESSOS DE REGENERAçãO DE UM CATALISADOR DE HIDRóLISE CICLIZANTE DE AMINONITRILA EM LACTAMA E DE FABRICAçãO DE LACTAMAS". A presente invenção refere-se a um processo de regeneração de um catalisador de hidrólise ciclizante de uma aminonitrila para a fabricação de lactamas. Ela se refere mais particularmente à regeneração de catalisadores sólidos utilizados nos processos de produção de lactamas por hidrólise ciclizante de aminonitrilas. Este processo de regeneração consiste em tratar o catalisador usado ou em fim de ciclo, a uma temperatura compreendida entre 300<198>C e 600<198>C por uma atmosfera oxidante.
