Abstract
This invention relates to systems and methods for catalytic steam cracking of non-asphaltene containing heavy hydrocarbon fractions. The method enables upgrading heavy hydrocarbons to hydrocarbons capable of being transported through pipelines and/or a pretreated step before further treatment in an upgrading refinery, including the steps of separating the heavy hydrocarbon mixture into a light fraction, a full gasoil fraction and a vacuum residue fraction with or without at least partial reduction or asphaltenes; adding a catalyst to the full gasoil and/or to the blend of this with a reduced asphaltenes fraction and subjecting the catalyst-full gasoil and/or deasphalted oil fraction to catalytic steam cracking to form an effluent stream; separating the effluent stream into a gas stream and a liquid stream; and mixing the liquid stream with the light fraction and the vacuum residue fraction to form an upgraded oil. The system includes hardware capable of performing the method.
