Abstract

In order to understand asphaltene reactivity under hydrotreatment conditions, a new strategy is proposed. A cross-flow membrane ultrafiltration method is applied in order to control asphaltene aggregate size polydispersity. At the same time, a feedstock reconstitution method that allows asphaltene dispersion in maltenes is established. Catalytic tests are carried out, showing that the developed feedstock reconstitution method allows one to preserve asphaltenes' natural reactivity under hydrotreatment conditions. In further studies, the developed methodology will allow the study of the effect of asphaltene aggregate size on hydrotreatment activities by the reconstitution of feedstocks containing controlled aggregate size.
