N2 can be found as a component besides CO2 in possible feed gases like mine gas, weak gas, or steel mill gas. To determine whether there is an effect on the biological methanation of CO2 and H2 from renewable sources or not, the process was investigated using feed gases containing CO2, H2, and N2 in different ratios, depending on the CO2 content. A possible effect can be a lowered conversion rate of CO2 and H2 to CH4. Feed gases containing up to 47N2 were investigated. The conversion of hydrogen and carbon dioxide was possible with a conversion rate of up to 91 but was limited by the amount of H2 when feeding a stoichiometric ratio of 4:1 and not by adding N2 to the feed gas.}}, author = {{Hoffarth, Marc Philippe and Broeker, Timo and Schneider, Jan}}, issn = {{2311-5637}}, journal = {{Fermentation}}, keywords = {{biological methanation, CSTR, Methanothermobacter marburgensis, methane, carbon dioxide, dinitrogen, hydrogen, power-to-gas}}, number = {{3}}, publisher = {{MDPI }}, title = {{{Effect of N2 on Biological Methanation in a Continuous Stirred-Tank Reactor with Methanothermobacter marburgensis}}}, doi = {{10.3390/fermentation5030056}}, volume = {{5}}, year = {{2019}}, } @article{5435, abstract = {{Towards renewable energy systems, the coupling of multiple sectors is important and incorporates novel technologies where currently no models exist that correctly represent all transient effects. Therefore, we present a method that incorporates Hardware-in-the-Loop simulations where virtual components as models are coupled to real and experimental facilities in real time. By including experimental components, a higher validity can be obtained and the practical applicability of renewable energy scenario can be discussed more profoundly. In this paper, the considered energy system consists of an experimental biocatalytic methanation reactor, a real photovoltaic park, a regenerative fuel cell and short-term storage units to supply a residential district. A representative control sequence of the methanator is obtained by modeling the scenario as an optimal control problem. A first HIL simulation highlights that modifications of the instrumentation are required for a grid injection of the generated methane. The scientific approach can be applied to any energy system where some of the considered components are available as experimental or real facilities. Non-exisiting components are simply replaced by models. The presented approach helps to determine which parts or process parameters are crucial for the planed operation before the overall energy system is realized on a larger scale. (C) 2019 Elsevier Ltd.

The method is a variant of the Hardware-in-the-Loop (HIL) simulation where virtual components are combined with real experimental components of the evaluated system. In order to integrate the real components with minimal instrumentation efforts, measured quantities are included as information flows, only, while the physical power flows are connected to local supply structures, like the electric grid or gas distribution system. This contribution incorporates a biocatalytic methanation reactor as an experimental component to convert hydrogen and carbon dioxide into methane. Compared to the well-known Sabatier process, this reactor operates at lower temperature levels and does not need pure carbon dioxide. This allows a dynamic operation and makes it more flexible regarding the carbon dioxide source whose availability is often critically discussed. The virtual energy components are represented by real-time capable models describing their physical behavior. In a test scenario, the electrical energy supply of residential quarters is investigated where photovoltaic data and a modeled fuel cell system are included beside the real experimental methanation process. For the dynamical management of energy and operating gases, electrical and chemical storage units are considered as virtual components, as well. The previous described energy system allows various strategies regarding the operation of the components, especially the storage units. Therefore an optimized energy management is reasonable, based on a designated criterion, e.g. minimal operating costs or maximum energy efficiency. In order to find the global optimum, the method of dynamic programming is used to determine the optimal control sequence for an assumed operation case, e.g. given by the photovoltaic yield of the considered day. Finally, the found solution is tested in real-time by the proposed HIL simulation.}}, author = {{Griese, Martin and Hoffrath, M. and Broeker, Timo and Schneider, J. and Schulte, Thomas}}, journal = {{ECOS}}, title = {{{HIL simulation of an optimized energy management incorporating an experimental biocatalytic methanation reactor}}}, year = {{2018}}, } @article{5632, author = {{Broeker, Timo and Schneider, Jan}}, journal = {{Brauwelt }}, number = {{19}}, pages = {{530 --532}}, publisher = {{Carl Hanser Verlag}}, title = {{{Oxidativer Aufschluss von Biertreber}}}, volume = {{2018}}, year = {{2018}}, } @inproceedings{5636, author = {{Broeker, Timo}}, location = {{Essen}}, title = {{{Implementierung eines bedarfsgerechten Power-to-Gas-Konzeptes in CO2 emittierende Fermentationsanlagen}}}, year = {{2018}}, } @inproceedings{5644, author = {{Broeker, Timo}}, location = {{Essen}}, title = {{{Implementierung eines bedarfsgerechten Power-to-Gas-Konzeptes in CO2 emittierende Fermentationsanlagen}}}, year = {{2018}}, } @article{5576, author = {{Broeker, Timo and Hoffarth, Marc and Oppermann, L. and Wolff, V. and Neubauer, Pia Rebecca and Schneider, Jan}}, journal = {{BrewingScience}}, number = {{3-4}}, pages = {{74--84}}, title = {{{Oxidation of Brewers Spent Grain for the Release of Fermentable Sugars by Direct Pretreatment in an Electrolysis Reactor}}}, volume = {{70}}, year = {{2017}}, } @inproceedings{5579, author = {{Schneider, Jan and Hoffarth, Marc and Broeker, Timo}}, location = {{Ljubljana (Slovenia)}}, title = {{{Wet oxidation of spent grains from breweries for the production of fermentable sugars}}}, year = {{2017}}, } @inproceedings{5580, author = {{Broeker, Timo and Hoffarth, Marc and Heikrodt, Klaus and Schneider, Jan}}, location = {{Ljubljana (Slovenia)}}, title = {{{Study on the implementation of a biocatalytic power-to-gas reactor in a brewery}}}, year = {{2017}}, } @inproceedings{5583, author = {{Broeker, Timo}}, location = {{Lemgo}}, title = {{{Bioraffinerie und Sektorenkopplung – biokatalytische Methanisierung als Schlüsseltechnologie zur Implementierung von Power-to-Gas}}}, year = {{2017}}, } @inproceedings{5584, author = {{Broeker, Timo}}, location = {{Gelsenkirchen}}, title = {{{bioCONNECT - Wasserstoff und biogenes CO2 im Verbund}}}, year = {{2017}}, } @inproceedings{5585, author = {{Broeker, Timo and Hoffarth, Marc and Heikrodt, Klaus and Schneider, Jan}}, location = {{Barcelona/Katalonia}}, title = {{{Study on the implementation of a biocatalytic power-to-gas reactor in a brewery}}}, year = {{2017}}, } @inproceedings{5545, author = {{Hoffarth, Marc and Broeker, Timo and Wolff, V. and Mengedoth, C. and Heikrodt, Klaus and Schneider, Jan}}, booktitle = {{2.
