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.

竹种组成特性的描述:综述

本研究旨在通过文献综述来描述不同种类竹子的成年茎的成分特性。将竹的全纤维素(纤维素+半纤维素),木质素,灰分含量,总提取物含量和元素化学组成的数据与其他木质纤维素材料进行了比较。在最后的考虑中,发现竹,树种以及工业过程中使用的其他替代材料的物种和属之间的平均全纤维素含量相似。木质素含量随树木,竹子和其他材料的不同而不同,其中竹子的价值中等。生物质的氢/碳比为0.12至0.14,表明它们已高度碳化。竹子的平均氧碳比为0.96,这表明其表面具有较高的疏水性。竹种的平均氧值为44.04%,比木材的平均氧含量低(47.42%);高含量的氧导致更高的反应性,其中在热降解过程中生物质快速挥发。氧的存在降低了能量密度以及与烃类燃料的混溶性。发现竹子的提取物平均值最高,而其他种类的树种则显示相似的值。灰分最高的是替代材料物种,竹子根据特定标准也显示出很高的价值。高含量的氧导致更高的反应性,其中在热降解过程中生物质快速挥发。氧的存在降低了能量密度以及与烃类燃料的混溶性。发现竹子的提取物平均值最高,而其他种类的树种则显示相似的值。灰分最高的是替代材料物种,竹子根据特定标准也显示出很高的价值。高含量的氧导致更高的反应性,其中在热降解过程中生物质快速挥发。氧的存在降低了能量密度以及与烃类燃料的混溶性。发现竹子的提取物平均值最高,而其他种类的树种则显示相似的值。灰分最高的是替代材料物种,竹子根据特定标准也显示出很高的价值。
