Improvement of Ebullated-Bed Effluent Stability at High Conversion Operation Jo~ao Marques,* Simon Maget, and Jan J. Verstraete IFP Energies nouvelles, Rond-point de l’echangeur de Solaize, BP 3, 69360 Solaize, France ABSTRACT: This work concerns the study of sediment formation in ebullated-bed hydroconversion of vacuum residues and investigates ways to avoid their formation at high conversion operation. Tests were carried out in a bench-scale unit at high temperature using a vacuum residue feedstock. Feeds and effluents were characterized to follow sediment formation, as well as conversion, yield structure, and hydrotreating performances. It was found that co-processing a vacuum residue feedstock with low amounts (
