项目摘要
Realization of the "Energiewende" in Germany relies on efficient energy storage by conversion of electrical energy particularly into hydrogen generated by water electrolysis. For that purpose, hydrogen can directly be converted into synthetic methane via hydrogenation of CO2. Methane is a key substance not only for energy storage, but also for the value chain of the chemical industry.In view of the fluctuating supply of hydrogen, it would be desirable to perform the CO2 methanation reaction in catalytic reactors able to cope with dynamically changing feed streams. However, little is known so far about the design principles of dynamically operating catalytic reactors and stable catalyst systems able to withstand temporal changes of the gas composition and temperature. A consistent multiscale analysis of the system dynamics, covering the involved reaction and transport processes on a broad spectrum of time and length scales, is largely missing.The proposed research project considers the heterogeneously catalyzed gas phase hydrogenation of CO2 to methane using supported Ni- and Ru-catalysts. It has two main objectives: 1) dynamic multiscale analysis of the catalytic reaction coupled with mass and energy transport phenomena, i.e. from the active site over the catalyst particle to the reactor scale,2) rational design of a novel integrated catalyst-reactor system able to deal with dynamic operating conditions, under consideration of all design variables available on microscale (active catalyst phase), mesoscale (porous catalyst particle) and macroscale (catalytic reactor).For attaining these objectives, the project consortium combines interdisciplinary expertise in: a) catalytic material design and characterization (Prof. Roger Gläser, Leipzig), b) spatially-resolved monitoring of catalysts via ex situ, in situ and operando methods (Dr. Thomas Sheppard, Karlsruhe), and c) dynamic modeling, simulation and optimization of catalytic systems (Prof. Kai Sundmacher, Magdeburg).
在德国实现“Energiewende”有赖于电能的有效储存,特别是将电能转化为水电解产生的氢气。为此,氢气可以通过二氧化碳加氢直接转化为合成甲烷。甲烷不仅是储存能量的关键物质,也是化学工业价值链的关键物质。鉴于氢气供应的波动,在能够应对动态变化的进料流的催化反应器中进行二氧化碳甲烷化反应是可取的。然而,到目前为止,人们对动态运行的催化反应器和能够承受气体组成和温度的时间变化的稳定催化剂系统的设计原理知之甚少。对系统动力学的一致多尺度分析,涵盖了广泛的时间和长度尺度上涉及的反应和传输过程,在很大程度上是缺乏的。拟议的研究项目考虑了负载型Ni和Ru催化剂的多相催化CO2气相加氢制甲烷。它有两个主要目标:1)结合质量和能量传输现象的催化反应的动态多尺度分析,即从催化剂颗粒上的活性中心到反应器尺度的动态多尺度分析;2)合理地设计能够处理动态操作条件的新型催化剂-反应器系统,同时考虑到微尺度(活性催化剂相)、中尺度(多孔催化剂颗粒)和宏观尺度(催化反应器)的所有设计变量。为了实现这些目标,该项目联合体结合了以下跨学科的专业知识:a)催化材料设计和表征(Roger Gläser,Leipzig教授),b)通过非原位对催化剂进行空间分辨监测,C)催化系统的动态建模、模拟和优化(马格德堡的凯·桑德马赫教授)。
