Catalytic conversion of lignocellulosic biomass to high-valued
transportation petrol, jet and diesel fuels is of great importance to develop versatile
renewable energy and boost rural economy, thus receiving worldwide attention. However,
the state-of-the-art processes still suffer from low efficiency in yield and productivity,
which hinders the progress of its commercialization. Thus, it is essential to explore the
consolidated catalytic reaction and refinery process. Here we report an advanced
approach/process that could continuously produce long-chain (C5-C15) ketones from
lignocellulosic biomass in a cascade mode by integrating several bio- and chemical
catalysis reactions, which exhibits high efficiency and stable conversion rate (>70 %) in
alkylation reaction. This technology consolidated the acetone-butanol-ethanol (ABE)
fermentation, palladium catalyzed alkylation and in situproduct recovery, allowing the
catalytic reaction to proceed consistently and smoothly. The remarkable conversion
property is mainly attributed to excellent compatible linkage of chemical catalysis with
biosynthesis and process design to stabilize the activity of Pd catalyst. This validated
strategy for rational process design and integration of chemical- and bio-catalysis offers
great demonstration in producing high-valued transportation biofuels derived from
agricultural residues.
