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.
