In the present work, a hydrogen-free one-step catalytic fractionation of woody biomass using commercial β-zeolite as catalyst in a flow-through reactor was carried out. Birch, spruce, and walnut shells were compared as lignocellulosic feedstocks. β-Zeolite acted as a bifunctional catalyst, preventing lignin repolymerization due to its size-selective properties and also cleaving β-O-4 lignin intralinkages while stabilizing reactive intermediates. A rate-limiting step analysis using different reactor configurations revealed a mixed
