帮我润色以下段落使其符合科研论文的逻辑注意不要改变意思：Zhao等Zhao et al 2018通过酸碱综合处理从茶叶废料中提取纤维素结果显示经过酸处理去除了无定形区域使纤维素的结晶度指数增加了129。同时在热重曲线中未发现木质素的失重峰表明经过综合化学处理茶废料中的木质素被完全除去。Owolabi等 Owolabi et al 2017从油棕叶中提取微晶纤维素结果显示化学处理有效去除了木质素和半

Zhao et al. (2018) extracted cellulose from tea waste using acid-base combined treatment. The results showed that the amorphous region was removed by acid treatment, which increased the crystallinity index of cellulose by 12.9%. At the same time, no weight loss peak of lignin was found in the thermogravimetric curve, indicating that lignin in tea waste was completely removed by comprehensive chemical treatment. Owolabi et al. (2017) extracted microcrystalline cellulose from oil palm leaves, and the results showed that chemical treatment effectively removed lignin and hemicellulose, and improved the thermal stability of cellulose. Microcrystalline cellulose with a crystallinity index percentage of 62.3% can be used as green filler or reinforcing material in composite materials. The studies of many scholars (Melikoglu et al. 2019, Tarchoun et al. 2019, Azum et al. 2021, Hachaichi et al. 2021, Asif et al. 2022, Zeleke et al. 2022) have shown that high-purity and high-thermal-stability cellulose can be obtained through acid-base combined treatment. However, the extraction process produces some black liquor (which refers to the liquid containing dissolved lignin and hemicellulose in alkaline solution turning into black or brown color), which has a significant impact on the environment. Some scholars have utilized the black liquor produced during the extraction process to extract hemicellulose, which can be applied in the pulp and paper industry (Hasanjanzadeh et al. 2014, Liang et al. 2023) or as an additive in composite films (Chen et al. 2023) to reduce environmental pollution.
