Abstract
MÉTODO E DISPOSITIVO PARA PREPARAR UM AGENTE DE REDUÇÃO PARA USO EM UM PROCESSO DE PRODUÇÃO DE METAL E EQUIPAMENTO DE PRODUÇÃO DE METAL USANDO O MENCIONADO DISPOSITIVO. A presente invenção refere-se a um método de preparo de um agente de redução que tenha uma temperatura elevada para uso em um processo de produção de metal, compreendendo a) uma etapa de pirólise de aquecimento de um material carbonáceo de partida usando-se uma fonte de calor em que o material de partida é pirolisado até um grau de pirólise de pelo menos 80% em um produto carbonáceo parcialmente queimado que tenha uma temperatura elevada e produzir um gás de escape de pirólise compreendendo substâncias voláteis do material carbonáceo de partida, b) uma etapa de combustão para queimar o gás de escape da pirólise, produzindo assim um gás de escape queimado, em que a energia térmica do gás de escape queimado é usado como a fonte de calor na etapa a) ao levar o gás de escape queimado ao contato direto com o material carbonáceo de partida e/ou em que a energia térmica do gás de escape queimado é usado como fonte de calor na etapa a) pelo aquecimento do material carbonáceo de partida sem contatar diretamente o material carbonáceo de partida. A invenção também refere-se a um dispositivo preferido para executar o método conforme a invenção, um processo de produção de metal, tal como um processo de produção de ferro, fazendo uso de um processo de preparação de um agente de redução e ao equipamento para execução desse processo.
