Influences of temperature on flash pyrolysis products of asphaltite

Abstract

Seguruk (Sirnak, Turkey) asphaltite by flash pyrolysis in a fixed bed reactor with a heating rate 40 degrees C min(-1) at 400-800 degrees C (optimum 550 degrees C) under nitrogen atmosphere gave: solid residue (char), 67.68; oil, 13.28; and water, 0.99%. Seguruk asphaltite contained: asphaltene, 28.72; preasphaltene, 10.43; aliphatics, 52.54; aromatics, 5.05; and polar aromatic Compounds, 3.26%. Oil obtained from asphaltite is mainly aliphatic according to FTIR spectrum.
