Demonstrates enhanced aromatic yields in wet-torrefied microalgae using HZSM-5 coated biochar, suggesting improved fuel properties.

Key Points

The research aims to explore the catalytic pyrolysis process of wet-torrefied microalgae to enhance aromatic production while reducing oxygen and nitrogen content.
Wet torrefaction of Chlorella at 200 °C
Synthesis of HZSM-5 coated biochar catalyst
Catalytic pyrolysis at 500 °C with a catalyst-to-feedstock ratio of 20:1
Characterization using XPS and in situ DRIFTS
Six-cycle stability experiments of the catalyst
Up to 96.06% aromatics produced with 83.24% selectivity for benzene, toluene, and xylene (BTX)
Yield of 94.64 mg of aromatics per gram of feedstock
Reduction of oxygenates and nitrogenates from 82.14% to 3.26%
Coke yield from HZSM-5@biochar was 0.33%, significantly lower than HZSM-5's 1.87%
Scanning electron microscopy indicated more amorphous components and coke formation in used HZSM-5.
