1 Crude property
Tahe heavy crude blending appears thin black, flow property is good at room temperature, the normal property is shown in table 1. From which the properties are: low density(783.2kg/m3), low Conradson carbon residue(0.22m%),It is very good light crude.
From the narrow distillation yield, 350℃fraction is very good residuum FCC feed.
