Systems and methods for processing hydrocarbons are provided. A hydrocarbon can be distilled to provide a distillate, a gas oil, and a residue. The residue can include, but is not limited to asphaltenes and non-asphaltenes. The residue can be mixed with a solvent to provide a mixture. The asphaltenes can be selectively separated from the mixture to provide a deasphalted oil. At least a portion of the deasphalted oil and at least a portion of the gas oil can be hydroprocessed to provide a hydroprocessed hydrocarbon. At least a portion of the distillate and at least a portion of the hydroprocessed hydrocarbon can be cracked in a first reaction zone to provide a first cracked product comprising C2 hydrocarbons, C3 hydrocarbons, C4 hydrocarbons, and naphtha.
