ABSTRACT
The introduction of solvent deasphalting (SDA), on different refining schemes, bring to the refineries a verypromising solution for desulfurization problems and/or catalytic cracking processes in recent years. In this work,some effective parameters of SDA process such as temperature and solvent and residues nature have beenstudied on the different residues of an Iranian crude oil mixture (ÂșAPI 19.5) in a bench unit. All produceddeasphalted oils (DAOs) were almost free of asphaltene (
