Description
Increasing the yield of Gasoline has been the desire of every crude oil refining process in the oil industry. The
principal unit that has significantly contributed to increasing the yield of Gasoline is the Fluid Catalytic Cracking
(FCC) unit. The performance of the FCC unit is dependent on many parameters, substantively the catalyst-to-oil
ratio (COR) and the temperature of the catalyst (tcat) when entering the riser reactor. To understand the effect of
COR and tcat, a five-lump kinetics model was developed, and the simulated result was further plugged into
MINITAB 7.0 software in order to generate a set of empirical equation models. The empirical equation models
predicted the optimal yield of gasoline to be 56.83%, with corresponding optimal parameters of COR and
temperature of catalyst as 3.35 and 900 K, respectively. The actual yield of gasoline at 3.35 COR and 900 K
catalyst temperature was 56.78%, with a 0.09% error compared to the predicted yield of gasoline. The two
parameters were varied with the values from previous studies, and the predicted result compared to the actual is
7.8648 root mean square error (RMSE). Therefore, the empirical equation model is reliable in predicting the
yield of gasoline with respect to the COR and temperature of catalyst.
