    Abstract: Systems and methods for upgrading a hydrocarbon stream to a lower boiling point hydrocarbon feed material are disclosed. The system includes a feeding device to transport a hydrocarbon stream that includes an alternative feedstock. The hydrocarbon stream is partially cracked in a first cracking unit producing a lower boiling point hydrocarbon feed material, a catalyst rich heavy hydrocarbon stream, and coke. A slurry settler receives the catalyst rich heavy hydrocarbon stream and coke and separates the catalyst from the catalyst rich heavy hydrocarbon stream thereby defining a catalyst rich stream and a heavy hydrocarbon stream. A coking vessel receives the heavy hydrocarbon stream and coke and separates the heavy hydrocarbons from the coke thereby defining a heavy hydrocarbon stream. Finally, a second cracking unit that receives the lower boiling point feed material from the first cracking unit and produces olefins and aromatics.

    Abstract: A process is provided to partially upgrade heavy oil using two or more reaction zones connected in series, each reaction zone being a continuous stirred tank maintained at hydrocracking conditions. The heavy oil feedstock and a solid particulate catalyst are stirred to form pumpable slurry which is heated to a target hydrocracking temperature and then continuously fed to the first reaction zone. Hydrogen is continuously introduced to the reaction zone to achieve hydrocracking and to produce a volatile vapor stream carried upwardly by the hydrogen to produce an overhead vapor stream. The hydrocracked heavy oil slurry from one reaction zone is fed to a next reaction zone also maintained under hydrocracking conditions with a continuous hydrogen feed to produce a volatile vapor stream. The overhead vapor stream from each reactor zone is continuously removed, and the hydrocracked heavy oil slurry from the last of the reaction zones is removed.
