As part of a research project devoted to the improvement of processes for the elimination of volatile organic compounds in gas phase, the CNRS is recruiting a young researcher with practical experience in the fields of materials chemistry and / or chemical engineering and / or heterogeneous catalysis for a period of 18 months. Research activities will be hosted by the Catalysis and Solid Chemistry Unit, Material and Catalytic Remediation team (head: Jean-François Lamonier).
- Development of experimental know-how linked to the synthesis of catalysts and their physico-chemical characterization. Writing of scientific reports.
- Building of a catalytic setup for the oxidation of VOCs of different natures, validation of the setup, writting of technical note and protocol of use. Training of other researchers/students to the use of the setup.
- Measure of catalytic activity of various materials, results interpretation, and writing of scientific reports.
- Doctoral degree (PhD) in Chemistry or Chemical Engineering (or equivalent)
- Technical know-how in materials chemistry and heterogeneous catalysis
- Good knowledge of French and / or English language, supported by the production of scientific documents in one of these two languages (scientific articles, technical reports)
Manufacturers in the automotive industry are faced with specific problems: (i) a high variety of pollutants (aromatic and oxygenated solvents) in the air; (ii) low contents, for each pollutant, of a few hundred ppb to a few hundred ppm; (iii) high fluctuations in the flow rates to be treated. Trapping the different VOCs on adsorbent is a mature technology with recognized abatement efficiency, for low VOC contents, regardless of the flow rate of industrial gaseous effluents. These adsorbents are finally burned to ensure complete degradation of the pollutants when saturated.
The objective of the study is to develop an economically viable process for the VOCs elimination, flexible of use and adaptable to this particular industrial problem. The development of this process should allow to overcome the constraints linked to the three problems previously identified: treatment of low concentrations, variety of pollutants and simultaneous presence in the feed to be treated, and variable gas effluent flows. The results of this study will therefore be a decision aid for the ultimate choice of the most suitable treatment technologies, proposing viable response for an overall reduction of the VOCs emitted, associated with human and especially industrial activities.
Constraints and risks
Due to the specific nature of the position, the recruited scientist must be formed to the specific risks of implementing gas phase catalytic setup. The chemical risks associated with the use of VOCs are minimized thanks to the presence of continuous air extraction.
