Search for optimum conditions of Paulownia autohydrolysis process and influence in pulping process

In this study, we evaluated the potential of a species trihybrid Paulownia fortunei, tormentosa, and elongata as an industrial crop in terms of its contents in holocellulose, lignin, xylo-oligomers, monomers, and other glucan and its use for making cellulose pulp. Well-optimized biomass autohydrolys...
