Abstract:This work demonstrates an additive and hydrogen‐free 2‐step lignin‐first fractionation in flow‐through. First, solvolytic delignification renders lignin liquors with its native chemical structure largely intact; and second, β‐zeolite catalytic depolymerization of these liquors leads to similar monomer yields as the corresponding 1‐step fractionation process. Higher delignification temperatures lead to slightly lower β‐O‐4 content in the solvated lignin, but does not affect significantly the monomer yield, so a… Show more
