This study aimed to describe the component properties of adult stems of different species of bamboo through a literature review. The data of holocellulose (cellulose + hemicellulose), lignin, ashes content, total extractives contents, and elemental chemical composition of bamboo was compared with other lignocellulosic materials. In the final considerations, it was found that there is similarity in the average holocellulose content between the species and genera of bamboo, tree species, and other alternative materials that are used in industrial processes. The lignin content varied among tree species, bamboo, and alternative materials, wherein the bamboo presented the intermediate value. The biomasses show hydrogen/carbon ratios from 0.12 to 0.14, indicating that they are highly carbonized. The average value oxygen/carbon ratios of bamboo was 0.96, which indicates there is a higher hydrophobicity in its surface. The average oxygen value of bamboo species was 44.04%, bottom than that found for wood (47.42%); the high content of oxygen leads to a higher reactivity, wherein fast biomass volatilization occurs during the thermal degradation process. The presence of oxygen decreases the energy density as well as the miscibility in hydrocarbon fuels. The highest average values of extractives were found for bamboo, while the other groups of species showed similar values. The highest ash content occurred in the group of species of alternative materials, bamboo also presented high values according to specific standards. [ABSTRACT FROM AUTHOR] |
