Bi-functional and bi-metallic catalytic solvo-hydrothermal liquefaction for upgrading hydrocarbon of phenol-rich oil from kraft black liquor lignin

Process Safety and Environmental Protection, Journal Year: 2024, Volume and Issue: 189, P. 867 - 881

Published: June 17, 2024

This study primarily aimed to enhance the hydrocarbon of a solvo-hydrothermal liquefaction (S-HTL) process initially extracting phenolic-rich oil. To catalyze current process, HZSM-5 zeolite with its modifications were applied S-HTL. Ni2P was first introduced forming bifunctional catalyst and further coating it either Co, Mo, or Zn create bimetallic catalyst. The analysis showed that structure did not change after modifications. acid sites on found be principally responsible for hydrodeoxygenation upgrading oil yield, biomass conversion, generation. Catalytic HTL also produced compounds detected in non-catalytic which appeared largely promoted by Ni2P. Additionally, output, yield all substantially increased (supplemented Mo) about 20%, 5%, 15%, respectively. Moreover, Mo-supplemented pre-treatment could used 5 more cycles insignificant conversion reduction. Overall, synthesized bi-functional bi-metallic catalysts S-HTL improving generated increasing production.

Bio-Oil Production by Depolymerization and Hydrodeoxygenation of Lignins over Mg–Ni–Mo/Activated Charcoal in Supercritical Ethanol

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(21), P. 20747 - 20761

Published: Oct. 24, 2024

The depolymerization and hydrodeoxygenation (HDO) of kraft, sulfuric acid, organosolv lignins were investigated over an Mg–Ni–Mo/activated charcoal (AC) catalyst in supercritical ethanol for the production upgraded bio-oils. Supercritical served both as a solvent hydrogen source HDO. Three different types used feedstocks, their characterization was accomplished by elemental analysis, gel-permeation chromatographic (GPC), Fourier transform infrared spectroscopy (FTIR), NMR. Mg–Ni–Mo/AC also carried out N2 adsorption/desorption, temperature-programmed reduction using (H2-TPR), X-ray diffraction (XRD), scanning electron microscopy-energy-dispersive (SEM-EDS). bio-oil yield significantly enhanced employing catalyst. experiment with acid lignin resulted 75.4 wt % catalyst, which exceeded more than twice that obtained without at 350 °C, 1 h reaction time, to ratio 90:10 (w/w). optimal conditions kraft determined be 3 (w/w) ratio, 4 loading, formation 83.0 35.44 MJ/kg higher heating value (HHV).
