Abstract Enhancement of the main physicochemical properties of a natural bentonite was carried out by means of modifications using surfactant, reflux, microwave treatment and, subsequently, the incorporation of AlZr and AlCe species. The evolution of the main changes in each modification stage was evaluated by means of X-ray diffraction, N2 sortometry, scanning microscopy (SEM), NH3-TPD, NH3-DRIFTS and CO adsorption at low temperature. For the evaluation of the catalytic behavior, the dehydration-dehydrogenation reactions of 2-propanol and hydro-conversion of decane were used; both of which generate, in addition, information regarding the acidic properties of the materials. The correlation of the number, type and acid strength with the catalytic behavior, allowed establishing the effect produced by both the delamination method and the nature of the incorporated cation. This generated tools that allow controlling the physicochemical properties, and more specifically, the enhancement of the acidity of new supports based on this type of natural clay mineral.

膨润土作为酸催化剂载体的潜力

摘要 通过使用表面活性剂、回流、微波处理以及随后掺入 AlZr 和 AlCe 物质进行改性，可以增强天然膨润土的主要理化性质。通过X射线衍射、N2分选法、扫描显微镜（SEM）、NH3-TPD、NH3-DRIFTS和CO低温吸附等手段评估了各改性阶段主要变化的演变。对于催化行为的评价，使用了2-丙醇的脱水-脱氢反应和癸烷的加氢转化；此外，这两者都会产生有关材料酸性特性的信息。数量、类型和酸强度与催化行为的相关性，允许建立由分层方法和结合的阳离子的性质产生的效果。这产生了允许控制物理化学性质的工具，更具体地说，可以增强基于这种天然粘土矿物的新载体的酸度。
