Catalytic cracking of raw and hydrotreated petroleum residua
Heavy residual oils can be converted to lighter transportation fuels with high yields by catalytic cracking. With high sulfur and high metals resids, hydrodesulfurization should be considered. In addition to decreasing the sulfur, hydrotreating will reduce the metals to a manageable level and also improve the yields significantly. Even with the lower metals content of the hydrotreated feed, metals passivation with an antimony containing compound will give a significant decrease in the yields of hydrogen and coke and an increase in the yield of gasoline. Hydrodesulfurization plus metals passivation of the Arabian Heavy feedstock decreased the yield of hydrogen by 54%, decreased the yield of coke by 68% and increased the yield of gasoline by 46%. A summary of these benefits is presented.
