Comparison of the Coking Products from Heavy Petroleum Tars and Heavy Catalytic-Cracking Gas-Oil

Resumo

The slow coking of heavy petroleum tars and heavy catalytic-cracking gas-oil from AO Gazpromneft–Omskii NPZ (AO GPN–OPNZ) is considered. The liquid coking products of heavy oil residues are analyzed by gas chromatography, mass spectrometry, and IR spectroscopy. The variation in composition of the decomposition products in the coking of the two raw materials is described. The quality of the petroleum coke obtained is studied by optical microscopy and X-ray diffraction analysis.
