Pyrolysis Kinetics of Asphaltite by Thermal Analysis
Petroleum Science and Technology, 2006Abstract Pyrolysis properties and kinetic analysis of asphaltite were investigated by means of thermogravimetry (TG) and derivative thermogravimetry (DTG). Thermal experiments were carried out from ambient temperatures to 1000°C in nitrogen atmosphere at different heating rates.

Obtaining vanadyl porphyrins from asphaltite of sadkinsk deposit
Chemistry and Technology of Fuels and Oils, 1987A method of obtaining vanadyl porphyrins by acetone treatment of asphaltite was proposed. A 1 gram asphaltite sample and 200 ml of acetone were placed in a flask and refluxed by 1 hour. After cooling, the solution was filtered and the content of vanadyl porphyrins in the acetone extract was determined by a spectrophotometer. The product was obtained in

Radiation stable graft copolymers based on petroleum asphaltite
Solid Fuel Chemistry, 2014A new type of the latent reactivity of petroleum asphaltites, which manifested itself under the action of γ-radiation, was determined. γ-Radiation facilitates the conversion of the asphaltites into macromolecular initiators onto which the macromolecular chains of styrene, methyl methacrylate, and acrylic acid are grafted.
