The aim of this paper is to study the kinetic effect of hydronaphthalenics on the thermal cracking of alkanes and to demonstrate that tetralin can be employed as a model compound of the hydronaphthalenic fraction derived from a specific resinite (Dammar resin) present as structural subunits of asphaltenes in petroleum of southeast Asia and Australia. Indeed, Dammar resin and tetralin were pyrolyzed in the presence of n-hexadecane (nC16), at 330 °C under 70 MPa for time periods from 72 h to 1 week. In both cases, significant inhibition of the cracking of the nC16 was observed. A previous reactive network model for the nC16−tetralin mixture [from Bounaceur et al., Ind. Eng. Chem. Res. 2002, 41 (19), 4689−4701] was adapted and improved on the basis of our new experimental data. It includes 226 free-radical reactions and 1 molecular reaction (retroene reaction). The formation of the main productsnamely, alkanes, alkenes, 1-methylindane, and butylbenzeneis correctly described by the model. The kinetic model al...
