Abstract

MÉTODO PARA FORMAR UMA PENEIRA MOLECULAR DE CARBONO, E, MONÓLITO DE PENEIRA MOLECULAR DE CARBONO. Métodos para formar uma peneira molecular de carbono incluem carregar fibras de polímero em um molde e aquecer o molde contendo as fibras de polímero a uma temperatura na faixa de 50 °C a 350 °C para formar um monólito de polímero. O monólito de polímero é, então, pirolisado por aquecimento até uma temperatura na faixa de 500 °C a 1.700 °C. Um monólito de peneira molecular de carbono inclui uma primeira extremidade e uma segunda extremidade oposta à primeira extremidade, e fibras de peneira molecular de carbono alinhadas em paralelo a partir da primeira extremidade do monólito de peneira molecular de carbono até a segunda extremidade do monólito de peneira molecular de carbono. Canais se estendem da primeira extremidade do monólito de peneira molecular de carbono até a segunda extremidade do monólito de peneira molecular de carbono e as superfícies externas das fibras de peneira molecular de carbono são unidas. O monólito de peneira molecular de carbono tem uma densidade de célula superior a 500 células por polegada quadrada.
