This work aims to evaluate the impact of bentonite content on the structural, textural and mechanical properties of SBA-15 beads prepared by shearing using an Eirich mixer. X-Ray Diffraction analysis (XRD) of conventional and sheared SBA-15 powders and bentonite–containing beads confirms the attainment of hexagonal structure. According to the nitrogen adsorption–desorption isotherms, the bentonite content has a significant impact on mesoporous volume. SBA-15 beads containing 9.1 wt% of bentonite (B-SBA-Be9), 16.7 wt% of bentonite (B-SBA-Be17) and 33.3 wt% of bentonite (B-SBA-Be33) showed an increase in mesoporous volume of 15, 25 and 20%, respectively. Indeed, the presence of the basic bentonite-water solution during the preparation stage of the beads generates a chemical attack of the SBA-15 walls that leads to the increase in the mesopores size. Beads containing 16.7 wt% of bentonite present more promising result in relation to their good balance between textural properties and mechanical strength. Thus, this sample could be used for a future application as a catalyst support for desulfurization process. Therefore, these results confirm that porosity and mechanical resistance are strongly dependent on the bentonite content and beads preparation process, in comparison to literature data.

这项工作旨在评估膨润土含量对通过使用Eirich混合机剪切制备的SBA-15珠的结构，组织和力学性能的影响。传统的和剪切的SBA-15粉末以及含有膨润土的珠粒的X射线衍射分析（XRD）证实了六边形结构的实现。根据氮吸附-解吸等温线，膨润土的含量对介孔体积有重大影响。含有9.1 wt％的膨润土（B-SBA-Be9），16.7 wt％的膨润土（B-SBA-Be17）和33.3 wt％的膨润土（B-SBA-Be33）的SBA-15珠粒的介孔体积增加了15％，25％和20％。实际上，在珠粒的制备阶段碱性膨润土-水溶液的存在会产生SBA-15壁的化学腐蚀，从而导致中孔尺寸的增加。含有16.7重量％的膨润土的珠粒由于其在质地性能和机械强度之间的良好平衡而呈现出更有希望的结果。因此，该样品可作为脱硫工艺的催化剂载体用于未来的应用。因此，这些结果证实，与文献数据相比，孔隙率和机械强度在很大程度上取决于膨润土的含量和珠粒的制备过程。
