Abstract
One exemplary embodiment can be a process for producing a chemical feedstock. The process can include passing a feed to a hydrotreatment zone, passing an effluent from the hydrotreatment zone to a fractionation zone, passing a stream including one or more C5-C25 hydrocarbons from the fractionation zone to a fluid catalytic cracking zone to obtain an another stream including one or more C6-C10 hydrocarbons, and passing the another stream to an adsorption zone for removing at least one heteroatom compound having a sulfur or a nitrogen atom.

A process for producing a chemical feedstock, comprising:
- A) passing a feed to a hydrotreatment zone;
- B) passing an effluent from the hydrotreatment zone to a fractionation zone;
- C) passing a stream comprising one or more C5-C25 hydrocarbons from the fractionation zone to a fluid catalytic cracking zone to obtain an another stream comprising one or more C6-C 10 hydrocarbons;
- and
- D) passing the another stream to an adsorption zone for removing at least one heteroatom compound having a sulfur or a nitrogen atom.
An apparatus for producing a chemical feedstock, comprising:
- A) a fluid catalytic cracking zone;
- B) a gasoline hydrotreatment zone communicating via a line with the fluid catalytic cracking zone for receiving one or more C6-C10 hydrocarbons;
- and
- C) an adsorption zone communicating via another line with the gasoline hydrotreatment zone for receiving a hydrotreated effluent.
A process for producing a chemical feedstock, comprising:
- A) passing a feed to a hydrotreatment zone;
- B) passing an effluent from the hydrotreatment zone to a fractionation zone;
- C) passing a stream comprising one or more C5-C25 hydrocarbons to a fluid catalytic cracking zone;
- D) passing a stream comprising one or more C22+ hydrocarbons to an another fluid catalytic cracking zone to obtain a first stream comprising one or more C6-C10 hydrocarbons and a second stream comprising one or more C13-C18 hydrocarbons;
- E) passing the first stream to a riser in the fluid catalytic cracking zone;
- and
- F) passing the second stream to a hydrocracking zone.
