In this section, the project results are presented in brief with respekt to the project's objectives.
1) Benefits of integrated catalytic membrane reactors (CMR) demonstrated at TRL7
The demo plants for BOC and HYFO cases were running successfully for 2500 hours and 13000 hours, respectively. Highly relevant data were obtained in order to judge the economical and sustainability potential of the technology. Due to budget constraints caused by extremely high inflation some modifications concerning plant sizes and duration of operation had to be made for H2 and PDH cases. Demonstration phase for these cases started in Q4/2024. Except for the implementation at TU/e the PDH-case demonstrators ran at TRL 5 and TRL 6 at UNISA and TUPRAS for 500 hours at their expected operational range. For the H2-case, good progress could be achieved with the natural gas demonstrator implementation at CNH2/H2-Site. The biogas demonstrator could not be run at BioValo/ENGIE site as intended because the approval of the French authorities to operate the demonstrator was not available in due time. As a replacement, the demonstrator was operated at ICI premises for a limited amount of time in January and February 2025.
2) Improved and scaled up building blocks (TRL7) implemented in CMR
RKV delivered more than 300 alumina porous supports to TEC for membrane production. 195 finished membranes were delivered for installing two hydrogen production demo plants and 20 membranes were delivered for equipping 3 propane dehydrogenation demo plants. For the HYFO-case, 56 SiC-based, coated monoliths were provided for installation into the membrane reactor. Later on, another 52 -Al2O3 based coated monoliths provided by Rauschert/Hereon were installed into the HYFO-CMR-plant to perform a 2nd phase of demonstration for approx. 2000 hours. Membranes for the BOC case were chosen from commercially available types. Catalysts were developed, manufactured and provided for all the cases in sufficient quantities to run the demonstrators. The amounts of rhodium catalysts for hydrogen production needed to be adjusted as Rhodium has seen a unprecedented price increase.
3) Modelling for building blocks (micro) and system (macro) established for four application sectors
At building blocks level specific permeation models for each type of membrane (DS Pd and polymeric membranes) and for each type of catalyst have been developed. The building blocks models have been integrated within 4 different membrane reactor models, subsequently used in the system analyses against the identified benchmark technologies to assess the potential techno-economic advantages of the MACBETH solutions. All MR models have been implemented in Aspen Custom Modeler (ACM). One customized model for each family of reactions and processes similar to the ones studied in MACBETH was developed.
4) Business case for Lighthouse Catalytic Membrane Reactors (LCMR) developed
With the help of professors of TU/e and Polimi as well as the MACBETH consortium, this small team conducted market research and rebranded itself as Modelta B.V. which was officially registered at the Dutch Chamber of Commerce in October 2022. The team has expanded since 2024 to 4 people, now on top of the CEO and CTO having a market analyst and computational scientist. Modelta B.V. aims to specialize on modelling services and consultancy on membrane and membrane reactor technology for the manufacturing industry in the short and medium term, aiming to become a knowledge single-entry point on membrane reactor technology in the long term.
5) Education tools for disseminating project results to wide audience applied
A first Webinar on “Introduction to membrane reactors” was held on November 5th 2021. The webinar has been well received with 87 participants online. A winter school took place at TUE premises in January 2024. The knowledge generated in Macbeth is being integrated in different courses of academic Macbeth partners. Various doctoral and master theses have been carried out on Macbeth relevant research activities.
General disemination activities included 35 publications in public media, 31 scientific publications, 351 Social Media posts, 144 posts on project website, 13 project videos published as well as numerous press releases.
