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).
