PhD project

“Catalytic valorization of Hemicelluloses in an Innovative Compartmented Heterogeneous Reactor”

My PhD is part of the CHICHE project. The objective of this work is the design of a continuous process for hemicelluloses valorization, integrating several steps of reaction and separation in one compartmented reactor. The hemicelluloses valorization path chosen is the synthesis of polyols from hemicelluloses. Polyols are high value-added molecules primarily known because of food industry applications as substitutes to classic sweeteners, although these substances are also applied in cosmetic industries as moisturizing agents. In this project, the synthesis happens in three steps:

- Catalytic hydrolysis of hemicelluloses in sugars

- Separation of ex-hemicellulose sugars from the hydrolysis medium

- Catalytic hydrogenation of sugars into polyols.

 

My work consists in:

- Implement the reaction steps in continuous mode

- Optimize all three steps separately

- Modeling the synthesis steps

- Integrate all the steps in one continuous compartmented reactor
