Figure 1From: The influence of solid/liquid separation techniques on the sugar yield in two-step dilute acid hydrolysis of softwood followed by enzymatic hydrolysisSchematic illustration of the experimental designs for the evaluation of different acid hydrolysis processes. a) Without washing the solids, (using Material I as feedstock), and b) with washing of the solids between the two acid hydrolysis steps and (using Material II).Back to article page
