Name : Victor Nichanian

Function : intern at the CIRAD, in the BioWooEb research unit.

Description : Victor Nichanian, 22, is student at the University of Technology of Compiègne (UTC), in process engineering. From September 2014 to February 2015, he will be on an internship at the CIRAD, in the BioWooEb research unit. In the context of the INVERTO project (innovation in vegetal chemistry through torrefaction), it consists in an environmental assessment of the chemical valorization of condensable species produced by the biomass torrefaction.  After the torrefaction’s thermodynamic study of 4 biomasses (pine, ashthree, miscanthus and wheatstraw) at 3 temperatures has been made, he will have to define the energetic needs of a new system, composed of the torrefactor and the extraction process of condensable species. With the help of the software SimaPro, he’ll finally make a life-cycle assessment of the system, in order to evaluate its environmental aspect and to minimize its impact.

Themes : biomass, torrefaction, thermochemistry, thermodynamics, life-cycle assessment, environmental impacts
