Periodic Reporting for period 4 - MONACAT (Magnetism and Optics for Nanoparticle Catalysis)
Période du rapport: 2020-12-01 au 2021-05-31
MONACAT proposed a novel approach to address the challenge of intermittent energy storage. Specifically, the purpose is to conceive and synthesize novel complex nano-objects displaying both physical and chemical properties that enable catalytic transformations with a fast and optimum energy conversion upon magnetic or optical excitation. In this respect, MONACAT reported first a process of magnetically induced CO2 hydrogenation for chemical storage of intermittent energies which is now developed at the pilot scale with an industrial partner. The applications can however be much broaader since magnetically induced catalysis has further been applied to higher temperature reactions such as propane and methane dry reforming and propane dehydrogenation as well as in solution for biomass molecules transformations.
The new process of magnetically induced catalysis has two main advantages : i) the possibility to trigger a catalytic reaction within a time scale of a second. This is fully adapted to intermittent energies. ii) the energy efficiency, expected to be the highest for heating a ferromagnetic material. The results were excellent in terms of both catalytic activity and selectivity for methane as well as in terms of energy efficiency observed at the lab scale and expected on a large facility. This led to the design and realization of a pilot delivered in july 2021. The first use of this pilot will be to enrich biogas (ca. 1/3 CO2, 2/3 CH4) into pure methane and to inject it into existing gas delivery pipes. This pilot construction and pilot operation are financed by ToulouseTechTransfer and Téréga (https://www.toulouse-tech-transfer.com/wp-content/uploads/2020/12/cp-terega-ttt.pdf(s’ouvre dans une nouvelle fenêtre)).
In addition MONACAT explored a new concept of high temperature catalysis in solution thanks to the "overheating" of the catalyst by magnetic induction. This allows to perform at moderate temperature and pressure reactions traditionally carried out in much more severe conditions such as those involving the transformations of biomass derived molecules. But the concepts resulting from MONACAT also led us to develop in collaboration electrolysis assisted by magnetic induction where significant gains were observed.
Task 6 led to unprecedented reactions such as hydrodeoxygenation of biomass platform molecules in solution. These results were at the origin of two research contracts and to a proposal of collaboration within an international ANR program. Finally the results of Monacat inspired an ANR program on electrochemistry which was funded, a research contract on hydrogen storage and two projects in discussion with two other industrial partners.
Overall the results of Monacat produced so far 32 publications, 2 patents, 7 publications which are directly related to Monacat but do not involve temporary personnel paid by Monacat and over 10 papers in which Monacat will be acknowledged to be published within the next year. Furthermore Monacat raised an academic and industrial interest. Concerning the academic part, proposals of collaborations on magnetic catalysis originated from leading catalysis and nanoscience institutions in Germany, Italy, Spain and france. Concerning the industrial part this led to collaborations and contracts with 4 major industrial companies and two SMEs.
- a catalytic process for enrichment of biogas adapted to intermittency and small and dispersed gas supplies.
- new inductors, more energy efficient
- a collection of complex nano-objects displaying various catalytic properties and Curie temperatures for regulating their activity.
- new methods for measuring the real temperature at the surface of a magnetically activated catalyst; new cadmium free quantum dots and their exploitation for temperature measurements.
- a new concept of "overheating" in solution allowing to perform difficult reactions in mild conditions such as hydrodeoxygenation of biomass platform molecules or hydrogenolysis or aryl ethers, models of lignin derived molecules. Further applications in organic chemistry and in the field of biomass.
- transposition of the concept of magnetic heating / magnetic catalysis to other research areas such as electrochemistry, hydrogen storage and waste plastic treatment
