Abstract

resumo “processos integrados para purificar um material celulósico” trata-se de um processo para converter um material de partida em um material de polpa purificado, que compreende remover lignina de um material de partida para formar uma polpa úmida que compreende pelo menos 5% em peso de água, extrair hemicelulose da polpa úmida com um agente de extração e separar a hemicelulose extraída da mistura de extração para formar um produto celulósico que compreende menos hemicelulose que a polpa úmida. o agente de extração compreende um solvente de celulose e um cossolvente. o produto celulósico mantém vantajosamente sua morfologia de fibra celulósica. o processo envolve separar e recuperar hemicelulose e separar e reciclar correntes de processo empregadas no processo.abstract “integrated processes for purifying a cellulosic material” means a process for converting a starting material into a purified pulp material, which comprises removing lignin from a starting material to form a wet pulp comprising at least 5% by weight of water, extracting hemicellulose from the wet pulp with an extraction agent, and separating the extracted hemicellulose from the extraction mixture to form a cellulosic product that comprises less hemicellulose than the wet pulp. the extracting agent comprises a cellulose solvent and a co-solvent. the cellulosic product advantageously retains its cellulosic fiber morphology. the process involves separating and recovering hemicellulose and separating and recycling process streams employed in the process.
