NOVELTY - A biomass-processing system (1) has a hydrolysis apparatus (12) which produces hydrolysis-processed material containing glucose, fermentation inhibition component and biomass residue by hydrolyzing wood-type biomass, a solid-liquid separator (13) which separates hydrolysis-processed material to saccharide solution containing glucose and fermentation inhibition component, and solid material comprising biomass residue, gas-liquid contact apparatus (14) which removes fermentation inhibition component from saccharide solution, and a fermentation apparatus (15).    USE - System is used for processing biomass (claimed) e.g. wood chips and waste building material.    ADVANTAGE - The system enables efficient processing of biomass, without using adsorption agent for removing fermentation inhibition component, and catalyst.    DETAILED DESCRIPTION - A biomass-processing system has a hydrolysis apparatus which produces hydrolysis-processed material containing glucose, fermentation inhibition component and biomass residue by hydrolyzing wood-type biomass, a solid-liquid separator which separates hydrolysis-processed material to saccharide solution containing glucose and fermentation inhibition component, and solid material comprising biomass residue, gas-liquid contact apparatus which removes fermentation inhibition component from the saccharide solution by gas-liquid contact method, and a fermentation apparatus which produces ethanol obtained by fermenting process liquid, after removing fermentation inhibition component. An INDEPENDENT CLAIM is included for method of processing biomass, which involves producing hydrolysis-processed material containing glucose, fermentation inhibition component and biomass residue by hydrolyzing wood-type biomass, separating hydrolysis-processed material to saccharide solution and solid material, removing fermentation inhibition component from the saccharide solution, and producing ethanol by fermenting process liquid.
