Abstract
ABSTRACT In this study, the effect of temperature and catalyst on the conversion of lactuca scariola stems into liquid and solid products with catalyst (H3BO3, NaOH, Na2B4O7.10H2O, ZnCl2, K2CO3) and without catalyst at temperatures of 350, 450 and 550 °C was investigated by a method of pyrolysis, a method of thermochemical conversion. The highest liquid product yield was obtained in the presence of ZnCl2 (33.97%). The obtained liquid and solid products were examined by GC-MS, Elemental, FT-IR, SEM and 1H NMR analysis methods. While the temperature in the experiments with catalyst and without catalyst was 350 °C, 98 different compounds, consisting of aromatics, aliphatics, oxygenated, nitrogenated and polycyclic compounds are obtained in general; at 450 °C, 92 different compounds, and for 550 °C, 88 different compounds were obtained.
