Extraction of highly purified microfibrils from the renewable resources by using green technology

Abstract

The main task in preparing hemp shives for further processing is to remove noncellulosic substances without usage of strong chemical treatments applying the steam explosion (SE) auto-hydrolysis process. The results indicate that the SE has significant effects on lignin removal and distribution of hemp shives. Effects of pre-treatment temperature and duration on characteristics of the steam exploded shives are studied by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR).
