Catalytic Pyrolysis of Bamboo Residues for Composite Biochar and Bamboo Oil

Abstract:

This study attempted to recycle bamboo waste, based on catalytic pyrolysis (TiO₂ as catalyst), to produce composite TiO₂-bamboo charcoal and bamboo oil simultaneously. The yield and characteristics of TiO₂-bamboo charcoal were investigated by thermogravimetry, elemental analysis and SEM. The results indicated that the yield of bamboo charcoal decreased with the increase of temperature, and the influence of catalyst was not distinct; after adding TiO₂, the H/C and O/C ratios of charcoal were increased from 18.81% and 3.74% to 26.05% and 4.09% respectively, and the particles of TiO₂ were adhered to bamboo charcoal with a very porous structure. Using GC-MS, the composition of bamboo oil was analyzed and the results showed that there were about 9-10 compounds with contributed to more than 2% area, and phenol was the most compound detected in all of the samples.
