Asphaltene Cross-flow Membrane Ultrafiltration on a Preparative Scale and Feedstock Reconstitution Method
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.
