US 11,859,140 B2 · Integrated hydrotreating and hydrocracking with continuous hydrotreating catalyst regeneration

Abstract

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.

Dependent claims

An integrated hydrotreating and hydrocracking process comprising:

contacting a hydrocarbon oil stream with a hydrogen stream and a hydrotreating catalyst in a moving-bed hydrotreating reactor to hydrotreat the hydrocarbon oil stream, thereby producing a hydrotreated hydrocarbon product stream and a spent hydrotreating catalyst;
contacting the hydrotreated hydrocarbon product stream with a second hydrogen stream and a hydrocracking catalyst in a hydrocracking reactor to crack the hydrotreated hydrocarbon oil stream, 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.

2 more elements

A system for hydrotreating and hydrocracking a hydrocarbon oil stream, the system comprising:

a moving-bed hydrotreating reactor configured to hydrotreat the hydrocarbon oil stream and a hydrogen stream with a hydrotreating catalyst to hydrotreat the hydrocarbon oil stream and form a hydrotreated hydrocarbon product stream and spent hydrotreating catalyst;
a hydrocracking reactor fluidly connected to the moving-bed hydrotreating reactor and configured to crack the hydrotreated hydrocarbon product stream and a second hydrogen stream to form a hydrocracked hydrocarbon product stream;
a stripper fluidly connected to the moving-bed hydrotreating reactor and configured to strip the spent hydrotreating catalyst to form a stripped hydrotreating catalyst;
and
a catalyst regenerator fluidly connected to the stripper and the moving-bed hydrotreating reactor and configured to regenerate the stripped hydrotreating catalyst to form a regenerated hydrotreating catalyst.
