Fast-growing Paulownia wood fractionation by microwave-assisted hydrothermal treatment: A kinetic assessment

Microwave hydrothermal treatment (MHT), a novel advanced technology, was proposed for the fractionation of Paulownia wood (PW) at temperatures ranging 200–230 °C and residence times 0–50 min, corresponding to severities 2.93–4.70. This procedure allowed 80% xylan recovery as xylooligosaccharides an average 95% cellulose in pretreated PW biomass, showing selectivity treatment, that also compared conduction–convection heating autohydrolysis. Finally, kinetic model prediction using MHT, with ultimate goal being applied wide range feedstocks minimizing number parameters used. For that, two strategies were approached, allowing reduction 80 34 parameters, without significant influence fitting. To best our knowledge, this is first modelization MHT PW, taking into account all lignocellulosic fractions.
