“…The higher temperature within this zone and the existence of heavy metals such as vanadium and nickel (see Table 2 for oil composition and elemental analysis) catalyzed the liquid-phase oxidation. 41 The catalytic effect of the metals explained the steep decrease in the mass of the sample observed in the FD region. In this region, the DTG plots revealed sharp fluctuations (up and down) corresponding to a breakdown of the skinlike shape by the volatile fractions formed in the LTO region.…”

“…During the FD phase, the oxidation reaction between the gases generated from the previous step (LTO region) continued with the liquid hydrocarbon phase. The higher temperature within this zone and the existence of heavy metals such as vanadium and nickel (see Table for oil composition and elemental analysis) catalyzed the liquid-phase oxidation . The catalytic effect of the metals explained the steep decrease in the mass of the sample observed in the FD region.…”

“…The higher temperatures necessary are now attained and the presence of heavy metals like Vanadium, Nickel, Copper etc. catalyze liquid phase oxidation reactions [36,37]. Also, oxidative desulfurization (ODS) method used to reduce the sulfur content in HFO is carried out in the liquid phase in the presence of metal catalysts [38].…”
