NONWOOD FIBERS Chemical and morphological characterization of sugar cane bagasse

摘要

The main goals of this study were to characterize the chemical (pith and fibers fractions) and morphologic (fibers fraction) properties of sugar cane bagasse and the structure of the depithed bagasse lignin by two-dimensional nuclear magnetic resonance spectroscopy. Industrial whole bagasse was separated into two fractions: pith and depithed bagasse. The pith was only characterized chemically. The depithed bagasse was chemically and morphologically characterized.
