Abstract

CARBONO ATIVADO DE SUPERFÍCIE MODIFICADA EM ARTIGOS DE FUMO. A presente invenção refere-se a um carbono ativado de superfície modificada que é provido para reduzir a quantidade de partículas finas de carbono livres entre o carbono ativado. Através de modificação de superfície de carbono ativado com uma camada, o carbono ativado pode ter aumentada resistência mecânica e as partículas finas de carbono entre o carbono ativado podem ser fixadas à camada. Por isso, a camada permite que o nível de partículas finas de carbono livres entre o carbono ativado seja reduzido. Carbono ativado de superfície modificada pode ser usado em artigos de fumo de modo a permitir adsorção pelo carbono ativado com reduzidas partículas finas de carbono livres no artigo de fumo e a fumaça produzida.
