“…In conjunction with IMO-adopted lower sulfur emissions at 0.5% sulfur equivalent and also decreasing worldwide fuel oil demand, many attempts for bitumen production from these conversion vacuum residues have been made. Some researchers , declare the suitability of visbreaking residue for bitumen production and others , point deficiency of visbreaking residue related to thermo-oxidative stability and adhesion. Process severity also influences visbreaking residue bitumen-related properties. , There is scarce information about hydrocracking-originated vacuum residue suitability for bitumen production.…”

In relation to the constant requirement for reduction of sulfur level and low demand for fuel oil, this study presents an approach for utilization of unconverted vacuum tower bottom (UVTB) from the ebullated bed hydrocracking process, H-Oil technology, in bitumen production. The kinetic study shows a slower softening point increase for crude blend 70% Urals and 30% Middle Eastern than other feeds in the air-blowing process. Also, penetration values for straight run vacuum residue feeds decrease quicker than the increase in their softening point values. UVTB softening point increase at high temperature is faster and penetration decrease is slower than LNB SRVR. Air blowing is shown to improve the penetration index of UVTB to a greater extent than the SRVR one. The bottleneck of this new application of UVTB is its low resistance to hardening, determined by using a rolling thin film oven (RTFO), which limits its quantity up to 20−30% in blends.

“…It is known that bitumen may be produced from the raw material of definite composition [1][2][3]. Moreover, tars from naphthenic-aromatic oils may be used for the production of bitumen of various types and tars from highly paraffinic oils -for the production of only some building types [4].…”

The oxidation process of the paraffin gas condensate residual has been studied to obtain road bitumen. The investigation results concerning the residual joint oxidation with extract of oil selective treatment and low-paraffin tars are presented. It has been determined that bitumen obtained from the residual of paraffin gas condensate treatment does not meet the requirements setting for road bitumen. It is recommended to use the residuals for the production of building or covering bitumen.

Vacuum residuum was upgraded in an ultrasonic reactor of our own design. We found that during sonication in the absence of a hydrogen donor, the viscosity of the vacuum residuum is reduced by 10.98%; without sonication but in the presence of tetralin, it is reduced by 30.9%; and with combined tetralin treatment and sonication, the viscosity is reduced by 39.27%. The synergistic effect of ultrasound and tetralin results in a product with more stable viscosity, higher percentage of light components, lower density and lower pour point than obtained by separate application of these technologies.The amount of vacuum residuum that can be produced in oil refineries is steadily increasing, and may reach 50% of the crude oil [1][2][3][4]. Vacuum residuum is characterized by high density, viscosity, molecular weight, and ash content plus low H:C ratio [5-7], which is an obstacle to refining it on catalytic cracking apparatus for residual crude. Thus there is a need to develop a cost-effective technology for refining vacuum residuum that does not have the limitations of catalytic cracking.Many publications devoted to study of ultrasonic cavitation energy (including [8][9][10][11]) suggest that cavitation technology may be effectively applied to viscosity reduction in vacuum residuum. An ultrasonic generator converts electrical energy to mechanical vibrations, which are propagated within the vacuum residuum as ultrasonic waves [9,12]. The pressure fluctuation leads to generation of microscopic cavities within the vacuum residuum, which expand and violently implode, creating shock waves and thermal energy. The thermal energy and the vigorous
