Abstract

1 / 1 resumo “mã‰todos para a digestãƒo de sã“lidos de biomassa celulã“sica” a digestã£o de sã³lidos de biomassa celulã³sica pode ser intensificada na presenã§a de um solvente fenã³lico. mã©todos para a digestã£o de sã³lidos de biomassa celulã³sica podem compreender prover sã³lidos de biomassa celulã³sica em um meio de digestã£o compreendendo um solvente fenã³lico; e aquecer os sã³lidos de biomassa celulã³sica e o meio de digestã£o em uma unidade de digestã£o na presenã§a de hidrogãªnio molecular e de um catalisador em pasta fluida capaz de ativar o hidrogãªnio molecular, formando assim um componente alcoã³lico derivado dos sã³lidos de biomassa celulã³sica e liberando lignina dos sã³lidos de biomassa celulã³sica dentro do meio de digestã£o; os mã©todos podem compreender adicionalmente a conversã£o de pelo menos uma porã§ã£o da lignina em um solvente fenã³lico e o retorno do solvente fenã³lico formado a partir da lignina para os sã³lidos de biomassa celulã³sica.
