Xylitol is a low calorie sweetener that can be produced through bioconversion approach from lignocellulosic biomass requires pretreatment prior to the of xylose xylitol. Steam explosion (SE) an industrially scalable (PT) process with potential liberate monomers, however SE-PT has not been optimised for release multiple feedstock. The effect pressure, substrate weight, phosphoric acid loading concentration and residence time on four feedstock (wheat straw (WS), corn stover (CS), Miscanthus...

The first comparative pre-treatment study of Miscanthus (Mxg) and sugarcane bagasse (SCB) using steam explosion (SE) pressurised disc refining (PDR) pretreatment to optimise xylose xylo-oligosaccharide release is described. current investigation aimed 1) Develop optimised batch-wise parameters for Mxg SCB, 2) Scale from static batch dynamic continuous refining, 3) Identify, understand, circumvent scale-up production hurdles. Optimised SE released 82% 100% the available xylan. Scaling PDR,...
