Two-temperature stage biphasic CO2-H2O pretreatment of lignocellulosic biomass at high solid loadings

Jeremy Luterbacher

Most biomass pretreatment processes for monosaccharide production are run at low-solid concentration (<10wt%) and use significant amounts of chemical catalysts. Biphasic CO 2-H 2O mixtures could provide a more sustainable pretreatment medium while using ...
