HYDROCRACKING RESIDUES--THE POTENTIAL SOURCE OF ROAD BINDERS? (WITH DISCUSSION)

In this study, an attempt was made to compare the composition and properties of the 540 C+ distillation residue obtained from H-Oil hydrocracking process (65% conversion) with those of distillation asphalts, and to evaluate the behavior of their blends from the point of view of their performance as road binders. The following methods were used to evaluate the composition of hydrocracking residue: elemental analysis, measurement of molecular weight, heavy metal content, group composition by liquid chromatography, gel permeation chromatography, infrared spectroscopy, nuclear magnetic resonance, and simulated distillation by gas chromatography. The tests were performed on "virgin" materials and on different fractions obtained by liquid chromatography. Besides the above mentioned tests, the acid number, bromine number, Conradson carbon residue, trichloroethylene insolubles, tetrachloromethane insolubles, toluene insolubles, heptane/xylene equivalent, density and flash point were all measured. To evaluate the rheological properties of the hydrocracking residue and its blends with asphalt, common conventional tests were employed. Besides these, viscosity measurements at elevated temperatures and the creep test at low temperatures were utilized.
