Postdoctoral fellowship/position: New strategies to manage inorganic compounds in efficient steam waste gasification

RESEARCHER PROFILE: Postdoc / R2: PhD holders
RESEARCH FIELD(S): Engineering
MAIN SUB RESEARCH FIELD OR DISCIPLINES: Chemical Engineering
JOB /OFFER DESCRIPTION

Context: The position is in the frame of a national work program funded by the French National Research Agency. Consortium is made up of an academic laboratory (M2P2, Aix-Marseille Université) and ENGIE Lab CRIGEN (Centre de Recherche et Innovation Gaz et Energies Nouvelles), the ENGIE Group's center for research and operational expertise dedicated to gas, new energies and emerging technologies. The aim of the TIGRE project is to develop effective methods for full-scale modelling of the behavior of inorganic compounds in gasification reactors, considering the hydrodynamics of the system, heat transfer and the chemical nature of the various phases. You will be in charge to lead experimental work on a continuous gasifier. You will be integrated in a multidisciplinary team of experts in the field of gasification.

Scientific issues: The thermal gasification of waste represents a promising avenue for sustainable energy production and waste valorisation. However, the formation of unwanted by-products coming from the inorganic elements originally present in feedstock constitutes a significant hurdle for process design and optimization. Addressing these scientific bottlenecks requires a combination of experimental research and advanced modelling techniques to enhance gasification efficiency and improve the quality of the resulting syngas. It is in this context that an experimental setup was developed to study the performance of a bubbling fluidized bed at low fluidization velocity. The experimental setup is a continuous pilot of some kg/hours with gas cleaning and sampling facilities (gas and solids) allowing gasification to be performed under a vast set of atmospheres. This experimental procedure provides complete temperature, gas composition and flow rate data for balance and efficiency calculation. Experimental tests and associated analyses are conducted to establish possible synergy between different feedstocks to expand the possible applicable feedstocks. The final objective is to develop a comprehensive modelling of inorganics behaviour.

The innovation of this work is then the application of different feedstock management strategies and controlled operating conditions and the consequence of those strategies on the resulting outflows of the process. In the first six months, you ‘ll work on several biomass and waste such as received to collect data and trained on the experimental pilot by exploring a range of operating conditions. The study of the physico-chemical interactions of raw materials with the fluidizing medium and the gasification atmosphere is a key point for this period. In a second time, in collaboration with the team, you’ll contribute to the design of a dedicated experimental plan and tests specifications to optimize inorganics recovery. The team is composed of 10 researchers. Among them you will have to specifically work daily with two PhD students.

You may contribute to the development and comparison of gas sampling and analysis methods. Depending on experimental results, you may also contribute to the Improvement of the experimental pilot design. The project fits perfectly with the need to reduce dependence on fossil fuels and thus to the decrease of the environmental footprint of energy sector which is of major importance to meet the objectives of the European Union.
