Abstract

The main focus of this work was to investigate the thermal behavior of heavy oil and its low temperature oxidized products. The distributed activation energy method (DAEM) calculation results indicated that coke as fuel deposited from static low temperature oxidation (LTO) experiments can significantly reduce the activation energy of oxidized oil in high temperature oxidation (HTO) period, which brought the possibility for application of Tahe ISC technique without artificial ignition devices. The activation energy of the samples during the HTO period showed that after the conversion rate attained roughly 0.3, the remaining reactions became much more likely to occur.
