METHODS FOR PRODUCING BIO-OIL

Methods for producing bio-oil from a feedstock (e.g., lignocellulosic) involving (1) pyrolyzing the feedstock in an inert atmosphere in a reactor to produce bio-oil, bio-char and non- condensable gases; (2) recycling about 10 to about 99% of the non-condensable gases to the reactor to produce deoxyg...

Zusammenfassung:	Methods for producing bio-oil from a feedstock (e.g., lignocellulosic) involving (1) pyrolyzing the feedstock in an inert atmosphere in a reactor to produce bio-oil, bio-char and non- condensable gases; (2) recycling about 10 to about 99% of the non-condensable gases to the reactor to produce deoxygenated bio-oil; wherein the method is conducted in the absence of oxygen and wherein the method does not utilize externally added catalysts. L'invention concerne des procédés pour produire de la bio-huile à partir de matière première (par exemple lignocellulosique) comprenant (1) la pyrolyse de la matière première sous une atmosphère inerte dans un réacteur pour produire de la bio-huile, du charbon de biomasse et des gaz non condensables ; (2) le recyclage d'environ 10 à environ 99 % des gaz non condensables dans le réacteur pour produire de la bio-huile désoxygénée ; le procédé étant réalisé en l'absence d'oxygène et le procédé n'utilisant pas de catalyseurs ajoutés de manière externe.
