Abstract

In this work, we studied the thermal cracking of atmospheric residue from Tamsagbulag crude oil in the presence of hydrogen donor-decalin. The oil is highly paraffinic and has high a viscosity and low yield of distillate fraction. Therefore, deep processing is necessary to increase the yield of distillate fractions. The cracking experiments were carried out using decalin at two different concentrations (5% and 10 wt.% of feed) under a hydrogen pressure of 5 MPa. Additionally, a control experiment was conducted without the use of decalin under a nitrogen pressure of 0.4 MPa. The experimental temperature was 450°C and the duration varied from 60 to 180 minutes. The cracking process resulted in the formation of gaseous, liquid products, and coke from the atmospheric residue. The yield of liquid products was found to be two times less without decalin (49.0%) compared to decalin at 5% (82.42 wt.%) and 10% (86.67 wt.%) for 120 minutes. From these results, we have concluded that the optimal condition of the cracking process to obtain higher fuel fraction and lower gaseous and coke is the cracking process with 10% decalin for 120 min under a hydrogen pressure of 5 Mpa at 450°C.
