Abstract

This dataset contains Py-GC-MS data obtained from the pyrolysis of three different biomass in different experimental conditions. Specifically, Py-GC-MS was used to investigate the chemical composition of semivolatile pyrolysates from firwood sawdust, olive stone, and sewage sludge in the presence of molten Li₂CO₃-Na₂CO₃-K₂CO₃ salts. The effects of pyrolysis temperature (400-800 °C) and biomass-to-salt ratios (1:0, 1:2.5, 1:5, and 1:10) were assessed. Pyrolysis products from each biomass under all experimental conditions were identified, and their peak areas were integrated by extracting chromatograms at selected m/z ions. Integrated areas were normalized to the weight of the pyrolyzed biomass to evaluate the effects of temperature and salt on product distribution. Fisher tests were performed to assess the statistical significance of salt effects on pyrolysis product formation for each biomass.
