Thermal destruction of asphaltites in supercritical fluids

Russian Journal of Physical Chemistry B, 2010
The processes of thermal destruction of asphaltites recovered from the Rafaelita and Toribia deposits in the presence of water, benzene, tetralin, and ethanol in the supercritical state are studied. The solvent nature plays an important role in the thermal destruction, with the maximum conversion (99 wt %) of both asphaltites into liquid products being

Obtaining vanadyl porphyrins from asphaltite of sadkinsk deposit

Chemistry and Technology of Fuels and Oils, 1987
A 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, 2014
A 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.
