Project description

Scientific objectives: A plasma works on a different principle than thermal processes. It is very efficient in it activate and dissociate molecules, but lacks selectivity in molecule recombining. In addition, the physical influence of materials on the properties of the plasma plays a role important role. This is a new concept for packing / catalyst development material, adapted to the plasma, necessary for selective plasma catalytic conversion to maximize technology.

Therefore, the following scientific objectives are intended:
1) Unraveling the material-activity relationships to create breakthroughs in structured (activated) packing materials that increase the selectivity towards specific products. Purpose: it defining the physical and chemical / catalytic effects to improve plasma performance to increase.
2) Improving plasma-based CO2 conversion processes. The goal is the product send selectivity to specific products by changing the (catalytic) packing materials with an increase in energy efficiency and space time yield at the same time. Purpose: "space increase time yield "by at least a factor of 6 over the plasma process without packing. An energy cost less than 15 eV / converted molecule CO2 or similar or better than thermal processes. 80% selectivity is proposed, although this is highly product dependent.
3) Demonstration of the benefits and limitations of using non-equilibrium plasma reactions towards selective formation of Cl to C3 platform chemicals.
4) Innovative methods for the development of (activated) materials, as improvement on the current technologies
5) To demonstrate the feasibility of the selective plasma catalytic production of inorganic amines from nitrogen and water. Purpose: to demonstrate feasibility for the formation of hydroxylamine. Fallback option: N0 / N02 with a minimum conversion of 2% to allow easy separation and an energy cost comparable to the Haber-Bosch process (0.48 MJ / mol or ~ 5 eV / molecule).
6) Compatibility of plasma conversion with dilute, mixed and / or crude CO2 streams demonstrate. Explore the benefits and limitations for the valorization of different types of CO2 waste streams. We aim for the synergistic advantage (or at worst the insensitivity) of plasma catalytic conversion, selectivity and efficiency at specific percentages of demonstrate impurities in CO2 streams other than the hydrogen sources.
7) Provide information on the impact of plasma catalytic processes on the supply chain by identifying techno-economic and environmental benefits.
8) Demonstrate how the profitability of plasma catalytic processes is affected by different forms of uncertainty for both CO2 conversion and N-fixation. Goal: the crucial R&D identify steps to address these uncertainties.
