“…These techniques include thermal processes, such as in situ combustion and steam-assisted gravity drainage (SAGD) (Cavallaro et al 2008;Moore et al 1999;Greaves et al 2001;Kumar et al 2011;Kapadia et al 2010;Speight 1970;Jiang et al 2005;Fan et al 2004;Maity et al 2010), and cold techniques, such as treatments using diluents like natural gas condensate (Luo et al 2007a, b;James et al 2008;Castro et al 2011;Cavallaro et al 2005). The latter (i.e., cold process) is used to improve the crude oil by dilution or destabilization, and deposition of the asphaltene components in the reservoir by injecting solvents that have a direct impact on viscosity reduction (Luo et al 2007b;Cavallaro et al 2005).…”

“…The latter (i.e., cold process) is used to improve the crude oil by dilution or destabilization, and deposition of the asphaltene components in the reservoir by injecting solvents that have a direct impact on viscosity reduction (Luo et al 2007b;Cavallaro et al 2005). The more frequently employed thermal techniques for heavy oil upgrading address breaking the heavier compounds of oil using combustion processes (Moore et al 1999;Cavallaro et al 2008), low-temperature oxidation (Xu et al 2000;Wichert et al 1995), aquathermolysis (Jiang et al 2005;Fan et al 2004;Maity et al 2010), and pyrolysis, also called thermal cracking or thermolysis (Speight 1970;Kumar et al 2011;Monin and Audibert 1988;Nassar et al 2013a). However, most of these techniques do not exceed 20 %-25 % oil recovery or 50 % for the steam-assisted gravity drainage (SAGD) process (Butler 1998;Nasr et al 2003;Hashemi et al 2013).…”

Kinetics and mechanisms of the catalytic thermal cracking of asphaltenes adsorbed on supported nanoparticles

The production of heavy and extra-heavy oil is challenging because of the rheological properties that crude oil presents due to its high asphaltene content. The upgrading and recovery processes of these unconventional oils are typically water and energy intensive, which makes such processes costly and environmentally unfriendly. Nanoparticle catalysts could be used to enhance the upgrading and recovery of heavy oil under both in situ and ex situ conditions. In this study, the effect of the Ni-Pd nanocatalysts supported on fumed silica nanoparticles on post-adsorption catalytic thermal cracking of n-C 7 asphaltenes was investigated using a thermogravimetric analyzer coupled with FTIR. The performance of catalytic thermal cracking of n-C 7 asphaltenes in the presence of NiO and PdO supported on fumed silica nanoparticles was better than on the fumed silica support alone. For a fixed amount of adsorbed n-C 7 asphaltenes (0.2 mg/m 2 ), bimetallic nanoparticles showed better catalytic behavior than monometallic nanoparticles, confirming their synergistic effects. The corrected OzawaFlynn-Wall equation (OFW) was used to estimate the effective activation energies of the catalytic process. The mechanism function, kinetic parameters, and transition state thermodynamic functions for the thermal cracking process of n-C 7 asphaltenes in the presence and absence of nanoparticles are investigated.

“…The portion of the oil burnt as fuel is the heavy residue and contains the unwanted products. This type of catalytic process appears to be especially valid for heavy oils (Moore et al, 1999). Reservoir definition is the process of using data from a variety of length scales (pore-corereservoir) and sources (laboratory-field) to improve our understanding of reservoirs and their petrophysical properties.…”
