摘要: A delayed coking process for use in a unit that includes at least one drum (12), the producing coke product (16) is retained and stream (14) introduced into fractionator (20) to produce bottoms fraction (22), an intermediate (24) light (28), including steps of: a. introducing fresh hydrocarbon feedstock (18) containing undesirable sulfur and/or nitrogen compounds preheating lower portion of (20); b. (24b) adsorbent material (32) selectively adsorbs nitrogen-containing mixing zone (30) form slurry (34); c. discharging (22) from d. adding all or (34) mixed feedstream (38); e. (38) furnace (40) heating predetermined temperature; f. passing heated (42) (12) depositing (44) having adsorbed with on interior (12).
