  • Maximizing products of high value and minimizing incineration of side-streams is key to realize future biorefineries. In current textile production from forestry, hemicellulose is removed by prehydrolysis before delignification. The resulting prehydrolysis liquor is incinerated in the recovery boiler at low efficiency. This additional burden on the limiting recovery boiler reduces the pulp production. In this study, we demonstrate that prehydrolysis liquor can be upgraded, in 5 steps, to yield aviation fuels. Prehydrolysis liquors were dehydrated to furfural by zeolite catalysis. Furfural was selecitvely reduced to furfuryl alcohol by homogeneous catalysis. Rhenium-catalyzed Achmatowicz rearrangement gave a C5 intermediate susceptable to self [2+2] cycloaddition to give the C10 oxygenated precursor. By using a combination of Ru/C and zeolites, full hydrodeoxygenation was achieved. The resulting hydrocarbons, containing a strained four-membered ring, are preferred  aviation fuel components. This is an important step to show that aviation fuels can be produced sustainably from existing industrial side-streams.
