An integrated hydrotreating and hydrocracking process includes contacting a hydrocarbon oil stream with a hydrogen stream and a hydrotreating catalyst in a moving-bed hydrotreating reactor, thereby producing a hydrocarbon product stream and a spent hydrotreating catalyst; contacting the hydrocarbon product stream with a second hydrogen stream and a hydrocracking catalyst in a hydrocracking reactor, thereby producing a hydrocracked hydrocarbon product stream; processing the spent hydrotreating catalyst to produce regenerated hydrotreating catalyst; and recycling the regenerated hydrotreating catalyst to the moving-bed hydrotreating reactor.

Integrated hydrotreating and hydrocracking with continuous hydrotreating catalyst regeneration

This disclosure relates to methods of upgrading hydrocarbon feed stream, which can include separating the hydrocarbon feed stream into a heavy fraction and a light fraction, hydrotreating an aromatic feed stream with at least a first catalyst in a first reactor comprising hydrogen to produce a first product effluent, combining the heavy fraction with at least a portion of the first product effluent to form a mixed stream, and hydrotreating the mixed stream with one or more second catalysts in a second reactor comprising hydrogen to produce a second product effluent.

Methods of upgrading hydrocarbon feed streams

Methods for operating a system having two downflow high-severity FCC units for producing products from a hydrocarbon feed includes introducing the hydrocarbon feed to a feed separator and separating it into a lesser boiling point fraction and a greater boiling point fraction. The greater boiling point fraction is passed to the first FCC unit and cracked in the presence of a first catalyst at 500&#xb0; C. to 700&#xb0; C. to produce a first cracking reaction product and a spent first catalyst. The lesser boiling point fraction is passed to the second FCC unit and cracked in the presence of a second catalyst at 500&#xb0; C. to 700&#xb0; C. to produce a second cracking reaction product and a spent second catalyst. At least a portion of the spent first catalyst or the spent second catalyst is passed back to the first FCC unit, the second FCC unit or both.
