摘要： Methods and systems for producing olefins and aromatics are provided. Methods can include removing silica from the coker naphtha feedstock to produce a first effluent, hydrogenating the first effluent to produce a second effluent, reacting the second effluent to produce a third effluent comprising aromatics, a fourth effluent comprising olefins, and a fifth effluent, separating the fourth effluent to produce a propylene product stream, an ethylene product stream, and a sixth effluent, recycling the sixth effluent by combining it with the second effluent.

摘要： The presently disclosed subject matter provides methods for producing olefins and/or aromatics from coker naphtha. In a non-limiting embodiment, a method for producing aromatics includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to aromatization in the presence of a second catalyst to produce an aromatic-rich stream that includes benzene, toluene and xylene. In certain embodiments, a method for producing olefins includes hydrogenating the coker naphtha stream in the presence of a first catalyst to remove diolefins and sulfur, if any, to obtain a hydrogenated stream and subjecting the hydrogenated stream to catalytic cracking in the presence of a second catalyst to produce an olefin-rich stream that includes ethylene, propylene and aromatics.
