Optimization of the Stabilization Step within Hydrotreatment of Fast Pyrolysis Bio-Oil for Sustainable Production of Marine Fuels

Short Introductive summary

In response to the global demand for sustainable energy, this study addresses the challenges of upgrading Fast Pyrolysis Bio-Oil (FPBO) for marine fuel production. With the shift towards alternative fuels, FPBO, derived from sustainable biomass, emerges as a promising intermediary due to its unique specifications suitable for marine fuels. However, challenges like low heating value and high oxygenation necessitate efficient upgrading, a process often achieved through hydrotreatment (HDT). This research strategically focuses on catalytic optimization of the Stabilization step in FPBO conversion, employing a sequential approach involving low-temperature HDT followed by high-temperature hydrodeoxygenation (HDO). By utilizing two distinct FPBOs from different biomass sources, the study investigates the efficiency of Single-batch and Dual-batch conversion processes using commercial catalysts (Ru/C and Pd/C). Results indicate limitations in meeting marine fuel standards in the Single-batch process, while the Dual-batch process, specifically stabilizing FPBO2, shows a remarkable improvement in deoxygenation efficiency. Ongoing optimization efforts at higher temperatures and with newly dev
