Denver, CO, August 19, 2024
FEWLS research is present at the ACS FALL 2024 Conference in Denver, Colorado! Dr. Morais was invited to present her group's work titled "Unlocking the potential of zeolite-based catalysis for converting lignocellulosic biomass into sustainable aviation fuels". This work is part of her graduate student Odiri Siakpebru doctoral research, and aims the development of zeolite-based catalytic system to directly convert lignocellulosic biomass into sustainable aviation fuel (SAF)-range alkanes!

Presentation Abstract:
Sustainable Aviation Fuels (SAF) Grand Challenge was launched in 2021 aiming to supply enough SAFs to meet 100% aviation fuel demand by 2050. Although some biomass-to-jet fuel strategies (e.g., gasification followed by Fischer-Tropsch) have been approved by ATSM International, they often require multi-step approaches and are energy intensive. Also, the development of additional technologies is required to allow fuel supply chain resilience. In this work, we report the conversion of raw poplar into liquid alkanes (carbon yield of 25.0 ± 0.92 wt%) with high selectivity toward C7-C15 cycloalkanes (15.9 ± 0.37 wt%) and low level of oxygenated compounds (<2.7 wt%) at 270 °C, 3 MPa initial H2 pressure for 6 h using 10% Ni/H-β zeolite as a catalyst. The effect of temperature (250-270 °C), Ni loading (0-10%) and type of zeolite support (H-β, ZSM-5 and USY) on process performance was investigated. Finally, the role of mesoporous diameters of hierarchical HY and H-β zeolites for promoting C-C coupling reactions, which is critical for producing SAFs from biomass, will be discussed. The results from this work show that the presented technology has the potential to simplify the production of SAFs from lignocellulosic biomass in the future.
