Methane Generation form Oil Cracking: Kinetics of 9-Methylphenanthrene Cracking and Comparison with Other Pure Compounds and Oil Fractions

摘要

The aim of the study is to determine the apparent rate constants for methane generation form the 9-methylphenanthrene (9-MPh) thermal cracking in the temperature range 375-450 deg. C under a constant pressure of 120 bar to evaluate by extrapolation the thermal stability of methylated aromatics of crude oils in geological conditions. In the first step, based on the conversion of 9-MPh only, rate constants were determined and the generated products were identified: the overall kinetic scheme was compared to that proposed in the literature for the 1-methylpyrene thermal cracking (Smith, C.M.; Savage, P.E. Energy Fuels 1992, 6, 195-202).
