Investigation on the hydrocracking reaction of heavy residues

Two basic investigations wiU be described here. In both experimental series, a batch reactor with a volume of 108 cm was used for the hydrocracking reaction. The first 

The second, more extensive, investigation on nine vacuum residues (VR) and two derived visbreaker residues (VVR) used reactions at three different temperatures (410 °C, 440 °C, and 460 °C), with a constant residence time of 30 minutes, and cold hydrogen pressure of 90 bar. The aim of this experiment was to investigate the influence of the origin of the eleven residues, from five different oil regions, upon their reaction behavior [4-42]. 

The products of the reactions, that is, the gases, high-volatile oil (naphtha), low-volatile heavy oil, and solid residues, were isolated after the reaction (after quenching) for analysis. The isolated heavy oils were investigated using thermoanalytical methods. In addition the kinetics of the pyrolysis reaction were investigated in the second series of experiments.
