Non-Hydro Refining of Coker Diesel Oil

Abstract

Coker diesel oil is refined by extraction of furfural adding assistant in this study. The influences of different operating conditions, such as the amount of assistant, the solvent/oil ratio, the refining temperature, the refining time, and the settlement time, on the quality of refined oil were investigated in batch experiments, and suitable operating conditions under which coker diesel oil refined can meet product qualify specifications of 0# diesel oil were given out. These had been verified in continuous experiments, i.e., the amount of additive was 8 g/kg, the refining temperature was 70°C, the solvent/oil ratio (v) was 1.0, the settlement time was 30 min, and refining time was 30 min. The experimental results show that the influence of basic nitride on the stability of coker diesel oil is predominant.
