摘要

以富含纤维素的天然竹粉为原料，通过硫酸浸渍，炭化和磺化的过程，制备竹炭碳磺酸并将其应用于纤维素水解反应。首先对改性前后的竹粉及其主要成分进行热重分析，发现硫酸能打破竹粉组分之间部分原有的化学键，促进竹粉的热解过程，使竹粉在低温下进行热解与炭化。然后系统地研究浸渍比例、浸渍液浓度、炭化温度和磺化温度等因素对催化剂活性的影响，得到催化剂最优制备条件。最后采用XRD、BET、FT-IR和SEM等方法对竹炭碳磺酸进行表征，结果表明通过合理调控温度能使竹炭磺酸具有良好的孔结构和较高的磺酸量，且磺酸量可能和芳香碳环上的活泼氢数目有关。

Abstract

Bamboo carbon-based solid acid was prepared via sulfuric acid impregnation

carbonization and sulfonation with cellulose-rich bamboo powder as feedstock

and its application in cellulose hydrolysis was studied. Firstly

the results obtained by TG of raw and modified bamboo powders and their main components showed that sulfuric acid had significant effects on breaking the chemical bonds in bamboo power to promote the pyrolysis and carbonization processes at lower temperature. The systematically research was conducted on the impregnation ratio

impregnation concentration

carbonization temperature and sulfonation temperature

which strongly affected the catalytic properties of bamboo carbon-based solid acid. Then

the optimal preparation conditions were obtained. Finally

the bamboo carbon-based solid acid was characterized by XRD

BET

FT-IR and SEM. These results indicated that the bamboo carbon-based solid catalyst had a favourable textile structure and considerable sulfonic acid content

showing that the sulfonic acid content was related to the number of active hydrogen on the aromatic carbon.
