Abstract

ABSTRACT: 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 4.0 MPa, and solvent/VR ratio of 5 conformed to GB/T 15180–2010 and its asphalt mixture had excellent rutting resistance and water stability performance; meanwhile, DAO yield reached 42.7% and good quality DAO satisfied the feedstock requirement for catalytic cracking process.
