A scientific challenge invites teams of 3 to 4 scientists to propose innovative research, new or disruptive topics, to lift identified barriers, but also to promote interdisciplinarity and dissemination of information.
Biogas, derived from anaerobic digestion of organic matter, is a source of renewable energy with high energy and environmental potential. It is a complex mixture that contains different types of trace compounds, in varying amounts depending on the substrates, which can damage the storage and upgrading units (corrosion phenomena, toxic emissions).
Based on the methanization process that generates biogas and digestate, the BioCAD project aims to demonstrate that the carbon from digestate can be pyrolyzed to obtain an adsorbent material called biochar and that this biochar can be used to purify biogas, in particular CO2 or noxious and odorous gases.
The aim is to select new profiles of carbonaceous materials to obtain biochars as adsorbents, for the treatment of biogas and odorous gases, in order to optimize their storage and treatment conditions.
BioCAD focuses on optimizing the pyrolysis and adsorption process, by identifying the best operating parameters, in order to produce biochars best suited to the targeted applications (gas purification and storage).
