Some particular aspects such as the improvement methods of technological parameters for hot bitumen storage in a pipeline transport system, transportation and dosed supply to batch asphalt mixing plan...
Catalytic cracking of bitumen with steam was examined. The heavy oil fraction of bitumen reacted with active oxygen species generated from steam with the iron oxide catalyst, producing significant amo...
Middle distillates obtained by pyrolysis of oil shale and oil sands bitumen were denitrogenated by complex formation with CuCl2·2H2O, which reduced the nitrogen contents from 9900 to 2700 wtppm and fr...
In this work, the efficiency of 20 kHz frequency ultrasounds versus the classical stirring procedure was investigated on the solvent extraction of Jordanian El-Lajjun oil shale by employing a horn typ...
This paper presents results of the research and development of the process for preheating bitumen using solar energy obtained at the Polytechnic University of Timi?oara. The aim of the research was ex...
This paper deals with bitumen and bituminous mixes, using suitable mathematical models that take into account the parameters a ecting their elastic and plastic sti nesses. These parameters are stress ...
Pavement failure can be manifested by excessive cracking due to fatigue. Highway pavements are subjected to a repeated passage of wheel loading of varying magnitude and intensity. Fatigue has been def...
Canadian oil sands bitumen contains no naphtha, about 44% gas oils, and 56% vacuum bottoms, as well as many "nasty" materials such as sulfur, nitrogen, aromatics, carbon residue, metals, and asphalte...
Light (LGO) and heavy or vacuum gas oil (VGO) fractions from mixed Middle East crudes and respective fractions from a typical Canadian oil sands bitumen-derived synthetic crude oil (SCO) were blended...
Hydrothermal desulfurization was evaluated for the upgrading of bitumen in supercritical water with alkali, based on the formation and decomposition of thiophene derivatives. In the alkaline hydrothe...
This study aimed to clarify the characteristics of the upgrading reaction of bitumen in supercritical water with alkali compared to pyrolysis, and to obtain more information about desulfurization in ...
