Mise au point et caractérisation d'un liant alternatif au bitume pétrolier, produit à partir de résidus des microalgues

Autor: Borghol, Ilef

The aim of this work is to produce an alternative road binder from a renewable biomass with high potential: microalgae residues. The chosen thermochemical transformation process is hydrothermal liquefaction (HTL). First, this requires a deep understa
