In this study, the pyrolysis properties of asphaltite samples taken from Şırnak and Hakkari regions in a fluidized bed reactor under catalyst and non-catalyst conditions were determined by rapid and batch pyrolysis. Basic analysis, FTIR and XRF analyses were performed for the raw material. GC-MS analysis methods were used for liquid pyrolysis products and FTIR were used for solids. In order to acquire the condition of the highest liquid product yield in pyrolysis, several effective variables such as particle diameter, vacuum, nitrogen flow rate, temperature, raw material feed rate, catalyst type, raw material type and duration were experimented and the results were evaluated. In general, the vacuum effect has led to an increase in liquid product yield and a decrease in gas product yield. Liquid product yield increased at 700°C pyrolysis temperature in continuous feed system and 550 - 650°C in batch system. In the pyrolysis studies carried out, a maximum liquid product yield of 16.5% was achieved in the continuous fed reactor at 700°C temperature, 400 mmHg vacuum, 2 g/min feed rate and 500 µm particle size.
