Abstract
|
This work investigated the effect of different conditions of Pyrolysis Fuel Oil (PFO) thermal cracking of two PFO samples on liquid, solid and gas product yields and asphaltene removal efficiency in a newly designed experimental setup. There is no need to use a catalyst, simple operating system and experiment conditions. The ability to use water as a cheap carrier gas and high asphaltene extraction efficiency without the use of solvents are outstanding benefits of this method in upgrading PFO. The yields of liquid, solid and gas products were compared in various operating conditions and the optimum experimental conditions were obtained. The results revealed the best thermal cracking condition of PFO in terms of liquid yield and asphaltene removal in this setup for samples. The optimum conditions were 390 and 380°C for the reactor temperature of PFO-1 and PFO-2, respectively; 150°C for the temperature of carrier gas and 100 ml/min for carrier gas flow rate. In these circumstances about 70 and 53 wt% of the liquid product, 25 wt% of the solid products, and 5 wt% of the gas product are generated and the asphaltene separation was reached about 95 and 96.5%.
