The global supply of high-quality crude is decreasing and, at the same time, the requirement for clean sulfur-free products is increasing. During the last decade, ebullated-bed residue hydrocracking has gained increasing interest due to its capability to produce high-quality, light and middle distillates in an economically effective way from heavy residuum oils.¹ Major economical drivers for ebullated-bed hydrocracker processes are run length, maintenance costs and most important, the achieved conversion. Very often, a compromise is made between unit operations and conversion due to fouling.²
