Abstract

MéTODOS PARA REGENERAçãO DE CATALISADOR E PARA PREPARAçãO DE SAIS HIDROXILAMÈNIO. Platina é aplicada a um veículo tal como grafita para formar um catalisador de platina. O catalisador se toma envenenado por um metal como resultado do uso do catalisador na preparação de sais hidroxilamónio. Um método para regenerar o catalisador dissolve a platina e o metal em um ácido. O método também adiciona sulfato de amónio ao ácido para precipitar a platina. O sulfato de amónio é um sub-produto de um processo comercial para sintetizar caprolactama. Além disso, o método precipita a platina sobre o veículo para sua reutilização na preparação de sais hidroxilamónio e na preparação da caprolactama.
