ΠερίληψηPyrolysis of high acidity olive oil, olive husk oil and animal fat was carried out under different atmospheres (vacuum, N2 and CH4), at constant temperature and different residence times. Bio-oils were the main pyrolysis products, with mass yields from 55.2% to 88.9%. The use of nitrogen or methane atmospheres led to an increase in the formation of gas products (14.1% to 26%), while increasing the residence time resulted in higher yields of gases and solids. The pyrolysis bio-oils contained 54.4% to 88.7% (w/w) of distillable liquids, collected as a light fraction and a heavy fraction. Both fractions were analysed by GC-MS to determine the hydrocarbon profiles and identification of functional groups. Vacuum pyrolysis promoted the formation of low molecular weight liquids while the use of a methane atmosphere increased the relative concentration of aliphatic components in the bio-oil.en
