Abstract
Undesirable components of traditional coking processes are selectively cracked or coked in the coking vessel by injecting an additive into the vapors in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack (or coke) these undesirable components that typically have a high propensity to coke, and are often precursors to coke in the coking process. These undesirable components can also be very problematic in downstream catalytic cracking processes, significantly contributing to coke on catalyst and catalyst deactivation. Exemplary embodiments of the present invention also provide methods to (1) decrease coke production, (2) increase liquid transportation fuels, (3) control the coke crystalline structure, and (4) control the quantity and quality of volatile combustible materials (VCMs) in the resulting coke. Pet coke from this process may have unique characteristics with substantial utility.
