1. A process for catalytically cracking hydrocarbons comprising:
feeding a hydrocarbon feed stream to an FCC reactor and contacting said hydrocarbon feed stream with catalyst to catalytically crack said hydrocarbon feed stream to provide a cracked stream;
disengaging said catalyst from said cracked stream;
fractionating said cracked stream into products including a slurry oil stream from a bottom of a main fractionation column;
heating said slurry oil stream;
separating said heated slurry oil stream into a cycle oil stream and a heavy stream under vacuum pressure.
