Abstract: A system and method for processing a treated feed slurry produced by a slurry reactor. The method and system include mixing a chemical separation feed with the treated feed slurry produced by the slurry reactor to chemically separate solid catalyst particles in the treated feed slurry by dissolving the solid catalyst particles using an acid or base in the chemical separation feed. A heavy oil upgrading process that includes the system and method is also described.

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.

Abstract: In some embodiments, an apparatus includes a first catheter movably disposed within a first lumen of a second catheter. The first catheter has a first occlusion member disposed at a distal end portion and the second catheter has a second occlusion member disposed at a distal end portion. A third catheter has a third occlusion member disposed at a distal end portion and is moveably disposable within a second lumen of the second catheter. The second catheter has a side port in fluid communication with the second lumen and the third catheter can be extended out of the second lumen through the side port. The first occlusion member, second occlusion member and third occlusion member can collectively isolate a target region including a portion of a first body lumen (e.g., a main vessel) and a portion of a second body lumen (e.g., a branch of the main vessel).
