Development of a Catalytic Oxidative Organosolv Process for the Fractionation of Lignocellulosic Biomass

Short Introductive summary

OxiOrganosolv is a technology developed in our laboratory that replaces the soluble acid catalyst typically used in organosolv biomass fractionation with oxygen atmosphere, achieving enhanced lignin removal and 100% cellulose recovery, with minimal formation of inhibitors to downstream microbial processes. In this work, we demonstrated the use of recoverable zeolite catalysts in this process to successfully reduce the severity of the operating conditions and achieve, at the same time, enhanced lignin and hemicellulose depolymerisation. We assessed the saccharification potential of the produced pulps from the new catalytic OxiOrganosolv and observed nearly 100% cellulose conversion and a three-fold increase in glucose yield compared to pulps produced without catalyst at similar conditions.
