Parallel reactor system for screening of heterogeneous catalysts

一个平行反应器系统，用于高通量筛选粉状或球团状的多相催化剂，有8至16个平行反应器（优选16个，但不是强制性的），在气相流反应中，可能会添加液体反应物。优先考虑高度灵活的系统，以处理TUC化学技术部当前和未来的项目，如萨巴蒂尔反应（二氧化碳的甲烷化），CSCDRM（甲烷的蒸汽和二氧化碳联合重整），氨- scr（选择性催化还原）氮氧化物与氨或CO2-FTS（使用二氧化碳的费托合成）合成燃料的生产。采购的系统应具有高无因次比l/d bbb50（反应器长度，内径）的反应器或可替换的反应器，以实现上述放热反应的l/d；反应器材料应允许在高反应性甚至腐蚀性气体混合物（例如H2S）中进行测试。用于测试的催化剂体积为0.1 - 4ml。平行化通过在多相催化中复制和更广泛地筛选复杂参数空间，增加了测量结果的可重复性。在开姆尼茨工业大学，以及据我们所知的自由萨克森州，还没有商业化的平行反应器系统来开发和测试具有较高催化活性的高档多相催化剂。在这种并联反应器系统中有效进行的催化剂筛选，以及寻找催化活性更高的高档催化剂和相应的动力学研究，是开发、设计和建造新的创新和可持续的装置和合成工艺的重要设计基础。用于在平行反应器中高通量筛选多相催化剂的平行反应器系统是建立技术知识库的基础，以提高测试程序的效率及其在当前和进一步发展的研究项目中的可重复性，最好具有当前面向应用的工业背景。

A parallel reactor system for high-throughput screening of heterogeneous catalysts in pulverized or pelletized form with 8 to 16 parallel reactors (16 preferred but not mandatory) in gas-phase flow reactions with the possibility of dosing liquid reactants is to be procured. Preference is given to a highly flexible system for handling current and future projects of the Chemical Technology department of TUC, such as Sabatier reaction (methanisation of carbon dioxide), CSCDRM (combined steam and carbon dioxide reforming of methane), ammonia-SCR (selective catalytic reduction) of nitrogen oxides with ammonia or CO2-FTS (Fischer-Tropsch synthesis using carbon dioxide) for the production of synthetic fuels. The system to be procured should have either reactors with a high dimensionless ratio l/d > 50 (l reactor length, d inner diameter) or replaceable reactors to realize the above mentioned l/d for exothermic reactions; the reactor materials should allow testing in highly reactive or even corrosive gas mixtures (e.g. H2S). The catalyst volumes targeted for testing are 0,1 - 4 mL. Parallelisation increases the reproducibility of the measurement results by replication and wider screening of the complex parameter space in heterogeneous catalysis. At the TU Chemnitz, and as far as known in the Free State of Saxony, there is no commercial parallel reactor system for the development and testing of upscale-capable heterogeneous catalysts with higher catalytic activity in fluid phase reactions. The catalyst screening that can be efficiently carried out in such a parallel reactor system as well as the finding of catalytically higher active upscale-capable catalysts and corresponding kinetic investigations are important design fundamentals for the development, design and construction of new innovative and sustainable apparatus and synthesis processes. The parallel reactor system for the high-throughput screening of heterogeneous catalysts in parallel reactors is fundamental for the creation of the technological knowledge base in order to increase the efficiency of the test procedures and their reproducibility for the current and further developing research projects, preferably with a current application-oriented industrial background.
