Multi-functional 4-fold parallel reactor systems for catalyst research

对于克里斯蒂安-阿尔布雷希茨大学无机化学研究所未来的催化剂研究，需要一个大型设备来进行具有足够测量能力的催化研究，并补充已经装备齐全的催化剂合成和表征领域。为此，需要一个多功能四重平行反应器来进行动力学测试，特别是关于COX和N_2的加氢反应，分别用于醇合成(甲醇和高级醇)和在例如30bar和80bar的加压下的氨合成。这些反应不仅对生产基础化学品非常重要，因此需要进行基础和应用研究，而且目前在化学氢和能量储存方面也得到了新的关注。基础研究问题涉及动态条件下的反应和失活机理以及新催化剂材料的开发。对于这两个研究方向，将进行快速催化试验，以及全面的动力学研究，以支持机理阐明和研究催化剂的稳定性。4折并行配置确保了研究方向范围内有足够的测量能力。对于蒸汽和酒精的联合投加，必须实施液体进料。为了对膨胀样品进行必要的连接表征，设备必须具有在测试后在惰性气体中移除催化剂的能力。所要求的装置是我们未来在结构/组成活性/选择性关系领域活动的重要组成部分，也是通过达到新的操作条件(高压)、建立新的测量方法(基于液体投加和惰性去除)以及通过提供迫切需要的测量能力来进一步发展我们的催化剂研究的先决条件。

For future catalyst research at the Institute of Inorganic Chemistry at Christian-Albrechts-Universität zu Kiel, a large-scale device is needed to perform catalytic studies with sufficient measurement capacity and to complement the already well-equipped areas of catalyst synthesis and characterization. For this purpose, a multifunctional 4-fold parallel reactor is requested to carry out kinetic tests, in particular on hydrogenation reactions of COx and N2 for alcohol synthesis (methanol and higher alcohols) and ammonia synthesis at elevated pressure of e.g. 30 bar and 80 bar, respectively. These reactions are not only of great importance for the production of basic chemicals and therefore subject to basic and applied research, but are currently gaining new attention in the context of chemical hydrogen and energy storage. Fundamental research questions address e.g. reaction and deactivation mechanisms under dynamic conditions as well as the development of new catalyst materials. For both research directions, rapid catalytic tests will be performed, as well as comprehensive kinetic studies to support mechanism elucidation and to study catalyst stability. The 4-fold parallel configuration ensures sufficient measurement capacity for the scope of the research direction. A liquid feed must be implemented for co-dosing of steam and alcohols. For the necessary connection characterization of the expansion samples, it is essential that the equipment has the capability to remove the catalysts under inert gas after the tests. The requested device is an essential building block of our future activities in the field of structure/composition activity/selectivity relationships and a prerequisite for further development of our catalyst research by reaching new operating conditions (high pressure), by establishing new measurement methods (based on liquid dosing and by inert removal), as well as by providing urgently needed measurement capacity.
