Three distinct catalysts were prepared and examined through a multitude of methodologies including FT-IR, BET, XRD and SEM/EDX/EDS. The HTL were made at temperatures ranging from 275 to 350 degrees C for a duration of 0 to 60 minutes. The liquid products obtained were subjected to elemental, GC-MS, FT-IR, and(1)H NMR analyses. The findings of this study demonstrate that NaF/Al2O3 catalysts effectively enhance the yield of liquid products. The liquid products that were obtained displayed an exceptionally elevated carbon content, with a maximum value of 80.97% achieved at a temperature of 350 degrees C. These liquid products exhibit superior heating values (HHV), which vary between 37.64 and 29.31 MJ/kg. The catalysts demonstrated efficacy in enhancing the liquid product yield, characterized by a heightened proportion of aliphatic compounds and a diminished ratio of oxygen constituents. It was determined that the obtained catalysts may have the potential to obtain liquid products with high carbon content and energy values.eninfo:eu-repo/semantics/closedAccessHeterogeneous CatalystSodium FluorideAluminaCrambe OrientalisHydrothermal LiquefactionArticle461Q3Q237483759WOS:001184677100001
