Title
(EN) A METHOD FOR RECOVERY OF OIL FROM BIOMASS
(FR) PROCÉDÉ POUR EXTRAIRE DE L'HUILE À PARTIR D'UNE BIOMASSE
Abstract
(EN)
The present invention relates to a method and apparatus for recovery of lipids from microbial biomass. The method comprises providing wet microbial biomass to thermal pretreatment of at least 100 ° C in a pressure vessel, subjecting the thermally pretreated microbial biomass to extraction using a liquid hydrocarbon as an extractant, and subsequently, recovering a product containing lipids.
(FR)
La présente invention concerne un procédé et un appareil pour l'extraction de lipides à partir d'une biomasse microbienne. Le procédé consiste à soumettre une biomasse microbienne humide à un prétraitement thermique d'au moins 100°C dans une cuve sous pression, puis à soumettre la biomasse prétraitée thermiquement à une extraction en utilisant un hydrocarbure liquide en tant qu'agent d'extraction, et subséquemment, à extraire un produit contenant des lipides.
