Heavy crude oil was upgraded into a lighter oil by means of hydrocracking on an acidic Mo–Ni liquid catalyst. Upgrading was measured in terms of specific gravity, viscosity, and distillates yield. The experimental results show that heavy crude oil was upgraded to an extent that depends on the severity of the reaction conditions; in all cases the hydrocracked oil was lighter, less viscous, and richer in valuable distillates (up to 60 wt % more) and contained less contaminants (sulfur and nitrogen) than the heavy crude oil. Hydrocracking experiments were carried out in a batch reactor that was operated at typical hydrocracking conditions, and the conversion was varied by modifying the reaction time over a range from 30 to 90 min or the reaction temperature from 350 to 450 °C. The formation of sediments and toluene-insoluble hydrocarbons increased as the reaction severity and conversion were higher; however, the values obtained were small and lower than those obtained with a commercial heterogeneous catalyst...

Heavy crude oil hydrocracking was carried out in a continuous reactor using a liquid acid catalyst. Experiments were conducted at 100 kg/cm2 pressure, a low to moderate reaction temperature (350 and 370 °C), and a hydrogen/hydrocarbon ratio of 10 m3/barrel for 180 h. The reaction temperature was below typical industrial hydrocracking reactors to avoid coke or sediment formation. Experimental results demonstrated that heavy oil was importantly upgraded, hydrocracked oil was less viscous, lighter, and with a higher content of valuable distillates than the original heavy crude oil. Kinetics of the process based on a five lump reaction scheme was determined using a modified Marquard–Levenberg optimization technique. The experimental and calculated yield comparison for each of the lumps is in close agreement.

To evaluate the effect of decanted oil (DO) from fluid catalytic cracking (FCC) units on product sediments in the ebullated bed hydrocracking process (EBHP), an experimental investigation was carried out, in which the reduction of sediments was evaluated by injecting DO into different points of the EBHP. This study was carried out in a H-Oil pilot plant, in which the operation of the industrial EBHP was simulated. To evaluate the effect on the reaction system, DO was injected into the feedstock drum, and to evaluate the effect on the product recovery section, DO was injected into different points of this section. The amount of oil injected was 5 and 10 vol % based on the fresh feed. Experimental results indicate that, when DO is injected together with the feedstock, its effect on sediment reduction is marginal. However, when DO was injected into the product recovery section, sediments were reduced up to 40%. The effect on the reaction system was marginal because the aromatic hydrocarbons of the DO, which ...

The appeal of individual mobility provided today by automobiles and light trucks with internal combustion engines, makes transportation the sector most resilient to a fuel substitution away from its dependence on oil. While the number of vehicles per capita and the distance traveled per vehicle are approaching saturation levels in the industrialized countries (IEA 2002), increases in population and income per capita, economic reforms and industry globalization can result in an off-trend accelerated growth of vehicles in the economies in transition (FSU and EE) and in the developing world (China, India and Latin America, mainly). The corresponding world road use energy consumption could reach a 200 percent increase from present levels by the year 2020, instead of an already worrisome “business as usual” projection of 75 percent (BAUER 2003, 2004). This paper analyses the mitigation effect on world oil demand and on its environmental impact that a policy of leapfrogging towards energy efficient internal combustion technologies and/or alternative vehicles – hybrid or fully electric – could have.
