TGA-Based Thermokinetics of High-Viscosity Oil Decomposition in the Presence of Nanocatalysts, Catalytic Additives, and Polymers

Abstract

The paper provides experimentally determined thermokinetics of the thermal decomposition of highviscosity oil (HVO) from the Karazhanbas fi eld, the Republic of Kazakhstan, in the presence of a Fe3O4 nanocatalyst, catalytic additives (nickel catalytic additives in microspheres prepared from coal ash), and polymers (such as polyethylene glycol and polystyrene) as hydrogen donors. The HVO decomposition thermokinetics (activation energy, pre-exponential factor, and rate constants), depending on the presence of nanocatalysts, catalytic additives, and/or polymers, were estimated by thermogravimetry methods in an inert nitrogen atmosphere. The experimental data (including HVO weight loss and weight loss rate vs. temperature) and the estimated thermokinetics of HVO decomposition can be used to create a database appropriate for mathematical modeling of the processing of HVO and heavy oil residues.
