In this work, the link between asphaltene stability and sediment formation in hydroprocessing of residua is evaluated using a couple of new techniques developed for asphaltene characterization. Several feeds as well as products coming from commercial units and pilot plants are examined in terms of asphaltene content and asphaltene stability. The results obtained confirm the relationship between stability, structural asphaltene characteristics and sediment formation in products. Correlations between stability and sediment formation were successfully used to predict sediment content.
