“…delayed coking and breaking with cleavage. The thermal conversion mechanism becomes complicated due to the complexity of heavy oil components (Xiao et al 2002). The factors affecting the heavy oil upgrading are catalyst management, heavy oil features, process design and financial aspects (Akhavan et al 2014).…”

“…37 The activation energies listed in Table 3 fall within the range reported in the literature. [21][22][23]44,45 It is generally accepted that the condensation behavior of oil components depends on their group composition. The heavier the oil component, the higher the activation energy for condensation.…”

By tracking the transfer of vanadium and nickel in pyrolysis products, a seven‐lump reaction kinetic model for pyrolysis‐based demetallization of heavy oil was established. During pyrolysis, the demetallization of heavy oil is achieved by condensing metal‐rich resins and asphaltenes to coke. The condensation of oil components originally contained in heavy oil differs greatly in reaction behavior, having the activation energy between 167 and 361 kJ/mol. As the pyrolysis progresses, the newly formed heavy components show a condensation behavior close to that of the light components. Limited by high activation energy and low initial fraction, the condensation of asphaltenes to coke and the resulting removal of metals contained in asphaltenes are hindered. Meanwhile, the condensation of light components has a major contribution to coke formation. An increase in reaction temperature accelerates the demetallization, but hardly changes the yield and component distribution of liquid products at the same metal removal rate.

“…The content of carbon (C) and hydrogen (H 2 ) are more than 95 % in most heavy crude oil . The thermal conversion mechanism becomes complicated due to the complexity of heavy oil components (Xiao et al 2002). According to Stratiev et al, heavy oils contain different fractions, which cannot be separated at atmospheric distillation and remain as residue.…”
