Selective preparation of jet fuels from low carbon alcohols and ABE at atmospheric pressure

Developing efficient jet-fuel synthesis route using bio-based low carbon alcohols or ABE (acetone/butanol/ethanol) is of great significance in reducing carbon emission. The objective of this work is to demonstrate that jet fuels can be selectively prepared from ABE and low carbon alcohols under atmospheric pressure condition. This controllable synthetic strategy was based on the two-step processes: selective dehydration of ABE (or low-carbon alcohols) into light olefins over the [email protected]@SAPO-34 catalyst and olefin polymerization into jet fuels over the ionic liquid catalyst ([bmim]Cl–2AlCl3). The optimizations of the catalysts and reaction conditions were investigated in detail. Under the atmospheric pressure, high ABE conversion (89.3%) and high jet fuel yield (71.5%) were achieved through coupling the two-step process.
