Trametes versicolor (L.) mushrooms liquefaction in supercritical solvents: Effects of operating conditions on product yields and chromatographic characterization

- Trametes versicolor were converted to liquid and gas products.
- 44, 24 and 25, 32 different types of compounds were identified by GC-MS obtained in acetone and isopropanol respectively.
- The produced bio-oil had higher heating values than the raw material.

In this study, the effect of reaction temperature, solvent and catalyst were examined on conversion of Trametes versicolor mushroom. Supercritical liquefaction experiments were made in a cylindrical reactor in acetone and isopropanol under supercritical circumstances with (Aluminium oxide, calcium hydroxide) and without catalyst at the temperatures of 250, 270, 290 °C. The bio-oils obtained at 250 and 290 °C in liquefaction were analyzed and characterized by chromatographic and spectroscopic techniques containing GC-MS, FT-IR and elemental analysis.
