Characteristics of slurry-phase hydrocracking for vacuum residue with reaction temperature and concentrations of MoS2 dispersed catalysts
TL;DR: In this article, the authors investigated the characteristics of slurry-phase hydrocracking of vacuum residue at a high conversion with a change of reaction temperatures and concentrations of the dispersed molybdenum (Mo Conc. 100-2000-ppm) catalyst.

TL;DR: In this paper, a kinetic model for the slurry-phase hydrocracking of vacuum residue was proposed under conditions of: 410 −450 −°C, 0.25 −1 hr−1, 160 −bar, 1500 Nm3/m3 of H2 to oil ratio, and 500 −ppm catalyst (Mo-octoate).

Investigation of asphaltene dispersion stability in slurry-phase hydrocracking reaction
TL;DR: In this paper, asphaltene dispersion stability and sediment formation for a slurry phase hydrocracking reaction of vacuum residue was investigated with changes of temperatures (405 −435 °C), LHSV (0.20 −0.45 ǫ h r - 1 ), pressures (80 −180 ǔ ) and superficial gas velocities ( 0.4 −2.2 ) in a bench-scale continuous system.

Effect of Alkyl Chain Length of Ionic Surfactants on Selective Removal of Asphaltene from Oil Sand Bitumen
TL;DR: In an attempt to find a more effective way to separate asphaltene from bitumen froth or bitumen emulsion by utilizing solvents, this paper added four different types of cationic (pyridinium series) and anionic (sulfate series) surfactants having different alkyl chain lengths and compared the results.

Reaction characteristics and sediment formation of slurry phase hydrocracking with vacuum residue in a bench-scale bubble column reactor
TL;DR: In this paper, the authors investigated the hydrocracking reaction performance of Mo-dispersed catalysts in relation to operating conditions in a bench scale slurry bubble column reactor and found that the VR conversion had a strong dependence on the product yield and properties.
