A fixed‐bed platinum or rhodium–cerium catalytic reactor is shown to effect a high carbon selectivity to pyrolysis oil from cellulosic feedstock. Heat is generated in situ by the sacrificial oxidation of pyrolysis vapors. High heat transfer rates within the catalyst bed allow for 100 % conversion of the cellulose feed while maintaining char‐free and autothermal operation. Variations in support geometry, catalyst, and H 2 addition are investigated to manipulate the yield of pyrolysis products.
