A process for upgrading a hydrocarbon feed, such as crude oil or other heavy oils, may include hydrotreating a hydrocarbon feed in a hydrotreating unit to produce a hydrotreated effluent that includes asphaltenes, coke precursors, or both. The process further includes hydrocracking the hydrotreated effluent in a hydrocracking unit to produce a hydrocracked effluent, adsorbing at least a portion of the asphaltenes, coke precursors, or both, from the hydrotreated effluent, the hydrocracked effluent, or both, separating the hydrocracked effluent into at least an upgraded lesser-boiling effluent and a greater-boiling effluent in a hydrocracked effluent separation system, and steam cracking the upgraded lesser-boiling effluent to produce olefins, aromatic compounds, or combinations of these. The process may further include recycling the greater boiling effluent back to the hydrotreating unit and hydrocracking a middle distillate effluent from the hydrocracked effluent separation system. Systems for conducting the processes are also disclosed.

Systems and methods of production for consistently sized and shaped optically anisotropic mesophase pitch from vacuum residue, one method including supplying processed vacuum residue to an extruder; heating the processed vacuum residue throughout a horizontal profile of the extruder from an inlet to an outlet of the extruder; venting hydrocarbon off-gases from the extruder along the horizontal profile of the extruder from the inlet to the outlet of the extruder; and physically shaping the consistently sized and shaped mesophase pitch at the outlet of the extruder for production of carbon fibers.

A method is provided for forming composite of nano-sized zeolite beta and hierarchical zeolite Y. The method includes synthesizing a hierarchical zeolite Y, synthesizing a gel of a nano-sized zeolite beta, forming a slurry of the nano-sized zeolite beta from the gel, and mixing the hierarchical zeolite Y with the slurry to form a composite. The composite is dried and an extrudable paste is formed from the dried composite. The extrudable paste is extruded to form extrudates, which are calcined to form calcined extrudates.

According to one or more embodiments presently described, a feedstock oil may be processed by a method which may include hydrotreating the feedstock oil to reduce or remove one or more of sulfur content, metals content, nitrogen content, or aromatics content to produce a hydrotreated oil stream; separating at least a portion of the hydrotreated oil stream into a at least a lesser boiling point oil fraction stream and a greater boiling point oil fraction stream in a first separator; hydrocracking the greater boiling point oil fraction stream; and steam cracking the lesser boiling point oil fraction stream.
