Abstract
Bamboo is one of the most significant biomass resources which has been used in
houses, flooring, construction of scaffolding and bridges, etc. The solvent
liquefaction process is one promising technique for effective utilization of waste
bamboo materials for the lignocelluloses which can be converted to liquid
reactive materials as biomass-based materials. Bamboo has the advantage of
providing liquefied products with a small range of variances. The components of
bamboo have high acidity in the presence of mineral acid catalysts and possess
constituents which can react with polyethylene glycol 400 (PEG 400). In this
study, waste bamboo materials have been used in liquefaction experiments. The
liquefaction process and liquefied residue have been measured according to the
liquefied conditions and the surface changes of waste bamboo samples observed
by a scanning electron microscope. The changes in the functional groups have
been analysed by a Fourier transform infrared spectrometer and the behavior of
the crystalline structures of liquefied bamboo has been determined by X-ray
diffraction. Other experiments, such as the degree of polymerization, have also
been carried out to confirm the results. It was found that increments of the
temperature and the amount of the acid catalysts improved the efficiency of
liquefaction. Meanwhile, the dissolution time of lignin was significantly shorter
than that of cellulose in the solvent liquefaction process of PEG 400.
