    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 vapour stream carried upwardly by the hydrogen to produce an overhead vapour 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 vapour stream. The overhead vapour stream from each reactor zone is continuously removed, and the hydrocracked heavy oil slurry from the last of the reaction zones is removed.

    Abstract: This invention relates to the conversion or hydrotreatment of petroleum or coal derived liquids in a novel ebullated-bed reactor system. The novel processing scheme results in a much simpler and less costly (investment and annual operating) ebullated-bed reaction system through the elimination of the high pressure, high temperature separator, hydrogen purification plant, and recycle gas compressor as well as a smaller hydrogen make-up compressor all resulting in substantial operational and construction efficiency.
