In this study, it was aimed to obtain the conversion of the heavy crude oil with 12.2 degrees API gravity into the liquid fuel-like condensate fractions having different boiling points of gasoline (initial boiling point-180), kerosene (180-240 degrees C), light diesel or distillate (240-290 degrees C), and gas oil (290-360 degrees C). A series of catalytic cracking runs were carried out on the pre-upgraded oil with using the molasses soil catalyst in different ratios of 0.0-10.0wt.%. The catalytic condensate and coke yields were found as 94.81wt.% and 2.42wt.%, respectively, for the optimal catalyst ratio of 2.5wt.%. The optimal cracking condensate and its fractions were characterized via spectroscopic and analytical test methods. The results revealed that the catalytic condensate was more rich in view of n-paraffinic hydrocarbons with lower carbon number of C-10-C-12 found in diesel fuel.
