This study dealt with a systematic investigation on the fluid catalytic cracking (FCC) performances of two bitumen samplesa partially deasphalted bitumen from a froth treatment process using a paraffinic solvent and a dry bitumen extracted using an aromatic solvent (the regular bitumen). Each bitumen sample was characterized and diluted with a heavy gas oil (an FCC feed) derived from Alberta conventional crude Rainbow Zama to produce two series of blends in 0, 10, 25, 50, 75, and 100 wt % bitumen concentrations. All samples were catalytically cracked in a microactivity test (MAT) reactor loaded with a wide-pore FCC catalyst at 540 degrees C. Liquid products from selected runs were characterized for hydrocarbon type and distribution of sulfur by boiling point. The improvement in cracking yields and product quality of bitumen after froth treatment with paraffinic solvent was assessed. The economic level of bitumen addition to heavy gas oil in FCC operation was also established.
