Abstract
The effect of atmospheric residue as a feedstock to a high-severity fluid catalytic cracking (HS-FCC) process has been investigated using a small-scale HS-FCC pilot plant (0.1 b/d) with a down flow reactor. This novel FCC process has been developed to enhance the yield of light olefins under high severity reaction conditions. Hydrotreated and virgin vacuum gas oils (VGO) as well as hydrotreated and virgin atmospheric residues (AR) were tested in the study. The yield of desired products such as gasoline and light olefins produced from virgin VGO cracking was 79 wt%, much higher than that obtained from a conventional FCC process whereas in case of hydrotreated VGO, the yield of desired products decreased to 76%. On the other hand, AR feeds exhibited performance similar to VGO with a slight increase in coke formation.
