BioCAD: Study of BioChar derived from methanisation for biogas and air treatment by ADsorption

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).

From the processes of biogas generation by pyrolysis, BioCAD aims at demonstrating that the carbon obtained can be used as a material of adsorption of biogas and odorous gas associated with these processes of green energy generation, i.e. allowing to purify them.

The objective is to select new carbon profiles derived from biochars (bio-charcoal) and adsorbents for the treatment of biogas and odorous gas from anaerobic digestion, in order to optimize the storage and treatment conditions of these gases.

BioCAD will focus on the optimization of the pyrolysis process, by identifying the best operating parameters, in order to produce the most adapte biochars-derived carbon for the targett applications (gas cleaning and storage).
