Effects on the yield of isolated cellulose in a scale-up model

This study focuses on fabricating a cellulose aerogel for efficient oil spill cleanup, using common reed (Phragmites australis) as the cellulose source. The process involves isolating cellulose from reed via traditional Kraft pulping, considering the effects of key factors on isolated cellulose content. After a two-stage HP bleaching sequence, the highest cellulose content achieved 27.2%, with 80% ISO brightness and 1% ash content under mild Kraft pulping conditions of 30% sulfidity, 20% active alkali, sustained cooking at 165 °C for 3 hours, and a liquor-to-reed ratio of 8:1. Subsequently, reed-based cellulose aerogel was fabricated via freeze-dried method using eco-friendly NaOH/PEG aqeous solvent system, which was then modified with (methyltrimethoxysilane) MTMS. The resulting aerogel exhibited remarkable characteristics, including a low density of 0.04 g/cm³, high porosity of 96%, superhydrophobicity with a water contact angle of 141°, and a superior crude oil adsorption capacity of..., Experiment methods at laboratory (scale up model) using the one-factor-at-a-time approach, , # Effects on the yield of isolated cellulose in a scale-up model

### Description of the data and file structure:

The Data_Tables.zip file contains four Excel files documenting the entire Kraft pulping of reed feedstock. The results are presented in the following files:

* **Effect of sulfidity on isolated cellulose.xlsx**: Sulfidity is a key variable in Kraft pulping that influences the efficiency of the pulping process and the quality of the isolated cellulose; 

- **Effect of active alkali on isolated cellulose.xlsx**: Active alkali (AA), consisting of NaOH and Na₂S, serves as the active agent in Kraft pulping; 
- **Effect of L:Q ratio on isolated cellulose.xlsx**: The liquid-to-solid ratio needs to be carefully controlled as it affects the diffusion of chemicals into materials containing cellulose, lignin, hemicellulose, and other components; 
- **Effect of cooking time on isolated cellulose.xlsx**: Cooking time affects cellulose degradation, influencing the yield and quality of th...

本研究以普通芦苇（Phragmites australis）为纤维素来源，旨在制备用于高效溢油清理的纤维素气凝胶。工艺过程包括通过传统硫酸盐制浆法（Kraft pulping）从芦苇中分离纤维素，并考察关键因素对分离纤维素含量的影响。在硫化度30%、活性碱20%、165℃恒温蒸煮3小时、液苇比8:1的温和硫酸盐制浆条件下，经两阶段HP漂白序列处理后，纤维素含量最高达27.2%，ISO白度为80%，灰分含量为1%。随后，采用环保型NaOH/PEG水溶液体系，通过冷冻干燥法制备芦苇基纤维素气凝胶，并使用甲基三甲氧基硅烷（methyltrimethoxysilane，MTMS）对其进行改性。所得气凝胶具有优异性能，包括0.04 g/cm³的低密度、96%的高孔隙率、141°水接触角的超疏水性，以及卓越的原油吸附能力……实验室规模（放大模型）实验采用单因素变量法，# 放大模型中分离纤维素产率的影响因素
