Revamping Fluid Catalytic Cracking Unit, and Optimizing Catalyst to Process Heavier Feeds

open access: yesApplied Sciences, 2023
H-Oil gas oils have a higher density and higher nitrogen content, and consequently much lower reactivity than straight-run vacuum gas oils during fluid catalytic cracking (FCC). The conversion of H-Oil gas oils observed in a laboratory catalytic cracking
