Title
(EN) HIGH TEMPERATURE LIGNIN SEPARATION PROCESS
(FR) PROCÉDÉ DE SÉPARATION DE LIGNINE À HAUTE TEMPÉRATURE
Abstract
(EN)
This specification describes a process to separate lignin from an aqueous mixture derived from a biomass feedstock, wherein the separation is done at or above critical temperature, usually above 60°C.
(FR)
Cette invention porte sur un procédé pour séparer la lignine d'un mélange aqueux issu d'une charge d'alimentation de type biomasse, la séparation étant effectuée à la température critique ou au-dessus de celle-ci, habituellement au-dessus de 60°C.
