Solvent deasphalting of Saudi residue to produce 30# hard ...
30 # asphalts produced directly by de-oiled asphalt (DOA) showed poor ductility at low temperature and deasphalted oil (DAO) yield was below 17.6%. Combination technology of solvent deasphalting and blending was investigated to produce 30 # asphalt and results demonstrated that the 30 # blended asphalt with Saudi residue and DOA prepared under conditions of temperature of 105°C, pressure of …
