A method for producing a mixture of short chain carboxylic acids (28) from biomass (10) includes adding biomass (10) to a reactor vessel, heating the biomass to crack it, removing undesired (20) and unreacted (18) materials and light ends (16) from the cracked biomass, and removing a mixture containing carboxylic acids having carbon chain lengths between C2 and C1 6 (24). A composition includes a carboxyl group- containing compound (28) derived by cracking biomass (10) and having a carboxyl carbon chain length between C2 and C 16.
L'invention porte sur un procédé de production d'un mélange d'acides carboxyliques à chaîne courte (28) à partir de la biomasse (10). Ce procédé comprend l'addition de biomasse (10) dans un récipient de réacteur, le chauffage de la biomasse pour la craquer, l'élimination de matières indésirées (20) et n'ayant pas réagi (18) et de fractions légères (16) à partir de la biomasse craquée, et l'élimination d'un mélange contenant des acides carboxyliques ayant des longueurs de chaîne carbonée entre C2 et C16 (24). Une composition comprend un composé à teneur en groupe carboxyle (28) issu d'un craquage de biomasse (10) et ayant une longueur de chaîne carbonée carboxylée entre C2 et C16.
