Parallel reactor system for screening of heterogeneous catalysts

将购置一个用于高通量筛选粉末状或颗粒状多相催化剂的平行反应器系统，该系统在气相流动反应中有8至16个平行反应器(16个优先但不是强制的)，可能会添加液体反应物。我们优先选择高度灵活的系统来处理TUC化学技术部当前和未来的项目，例如用于生产合成燃料的Sabatier反应(二氧化碳甲烷化)、CSCDRM(甲烷蒸汽和二氧化碳联合重整)、氨-SCR(氨选择性催化还原)氮氧化物或CO2-FTS(使用二氧化碳的费托合成)。拟采购的系统应具有高无量纲比L/d&gt；50(L反应堆长度，d内径)的反应堆或可更换的反应堆，以实现放热反应的上述L/d；反应堆材料应允许在高活性甚至腐蚀性气体混合物(如硫化氢)中进行试验。测试催化剂的目标体积为0.1-4毫升。并行化通过复制和更广泛地筛选多相催化中的复杂参数空间来增加测量结果的重复性。在工业大学开姆尼茨，据所知，在自由州萨克森，没有商业平行反应器系统，以开发和测试高档能力的多相催化剂，在液体相反应中具有更高的催化活性。能够在这种平行反应器系统中高效地进行催化剂筛选，以及找到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。在平行反应器中高通量筛选非均相催化剂的平行反应器系统是建立技术知识库的基础，以便提高测试程序的效率及其对当前和今后开发的研究项目的重复性，最好是具有当前以应用为导向的工业背景。

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.
