This paper summarizes the experience gained over seven years of operating an H-Oil ebullated-bed vacuum residue hydrocracking unit. The following key factors in improving the performance of H-Oil process were identified, including feedstock quality, catalyst condition, as well as loading and utilization of the unconverted vacuum residue. The optimum combination of these four factors allowed a vacuum residue conversion rate of about 90% to be achieved. The challenge still remains to determine optimal approaches to using the unconverted vacuum residue produced at higher conversion rates.
