A process of making a fuel or chemical from a biomass hydrolyzate is provided which comprises the steps of providing a biomass hydrolyzate, adjusting the pH of the hydrolyzate, contacting a metal oxide having an affinity for guaiacyl or syringyl functional groups, or both and the hydrolyzate for a time sufficient to form an adsorption complex; removing the complex wherein a sugar fraction is provided, and converting the sugar fraction to fuels or chemicals using a microorganism.
L'invention concerne un procédé de fabrication d'un carburant ou d'un produit chimique à partir d'un hydrolysat de biomasse, qui consiste à produire un hydrolysat de biomasse, à régler le pH de l'hydrolysat, à mettre en contact un oxyde métallique présentant une affinité avec l'un ou l'autre, ou avec le deux groupes fonctionnels de guaiacyle ou syringyle, et l'hydrolysat suffisamment longtemps pour former un complexe d'adsorption; à évacuer ledit complexe dans lequel on met une fraction de sucre, et à convertir ladite fraction en carburants ou en produits chimiques à l'aide d'un micro-organisme.
