Abstract

resumo “processos para purificar material celulósico” trata-se de um processo para tratar um material celulósico que compreende extrair o material celulósico com um agente de extração para extrair seletivamente hemicelulose do mesmo e separar a hemicelulose extraída para formar um produto celulósico que compreende menos hemicelulose que o material celulósico. o agente de extração compreende um solvente de celulose e um cossolvente. o produto celulósico mantém vantajosamente sua morfologia de fibra celulósica. os processos envolvem separar e recuperar a hemicelulose e separar e reciclar várias correntes de processo empregadas no processo.abstract “processes for purifying cellulosic material” means a process for treating a cellulosic material which comprises extracting the cellulosic material with an extracting agent to selectively extract hemicellulose therefrom and separating the extracted hemicellulose to form a cellulosic product comprising less hemicellulose than the cellulosic material. the extracting agent comprises a cellulose solvent and a co-solvent. the cellulosic product advantageously retains its cellulosic fiber morphology. the processes involve separating and recovering the hemicellulose and separating and recycling various process streams employed in the process.
