The oily sludge treatments catch widespread attention. But, management of sludge is difficult and costly undertaking. The oil recovery pyrolysis temperature, heating rate and carbon wt.% is discussed. The recovered aliphatic, aromatic, elemental components and gases were obtained with respect to the nitrogen flow rate. The present work showed that as the heating rate increases, both the %pyrolysis oil and gases increases up to 600 OC, while the %pyrolysis char decreases. Beyond 600 OC, the pyrolysis gases% increases, the pyrolysis oil% decreases while the %pyrolysis char continuous decreases. Gas chromatography, and calorific value used to examine the hydrocarbon compositions of the virgin, sludge, and pyrolysis oils.
