## Abstract

The present invention describes a process for the production of carbon black starting from a 360+ cut known as a slurry cut obtained from a FCC or RFCC unit, to which a vacuum residue type cut may be added, said process using a specific hydrotreatment unit.

## Claims

### Claim 1

A process for the production of carbon black with a sulphur content of less than 0.3% and preferably less than 0.1%, starting from at least one feed which is the slurry cut obtained from a catalytic cracking unit (FCC or RFCC), the process involving the following steps:
a step (FILT) for filtering fine solid particles contained in the slurry cut, resulting in a clarified slurry cut, i.e. containing less than 300 ppm and preferably less than 100 ppm of fine particles (less than 10 microns);
a step (RDS) for hydrotreatment of the clarified slurry cut, operating under the following conditions:
a) a pressure in the range 50 to 200 bars, and preferably in the range 80 to 120 bar;
b) a temperature in the range 300° C. to 420° C., preferably in the range 340° C. to 390° C.;
c) an HSV in the range 0.1 to 2.5 h−1, preferably in the range 0.4 to 1.0 h−1;
the catalyst used being a succession of at least two distinct hydrotreatment catalysts, and said hydrotreatment step producing an effluent with a BMCI value of more than 110;
a step (DIST) for distillation of the effluent from the hydrotreatment step, resulting in a “light” portion used as a cut in the fuel pool, and a distillation residue with a sulphur content of less than 0.3% and preferably <0.1%, and having a BMCI of more than 80, preferably more than 100, and with a density of more than 0.97 g·cm−3, preferably more than 1.0 g·cm−3, said distillation residue being introduced into the carbon black unit (CBU),
a step (CBU) for producing carbon black in the unit, which results in a final product with a specifications in accordance with the ASTM standard (grade 110 to 990).

### Claim 2 (depends on 1)

The process for the production of carbon black according to claim 1, in which the two catalysts used in the hydrotreatment unit (RDS) are, in succession (i.e. in the direction of flow of the feed to be treated):
a catalyst primarily ensuring hydrodemetallization (denoted HDM);
a catalyst primarily ensuring hydrodesulphurization (denoted HDS), the volumetric ratio of the HDM catalyst to the HDS catalyst being in the range 0.05 to 1, preferably in the range 0.1 to 0.5.

### Claim 3 (depends on 1)

The process for the production of carbon black according to claim 1, in which a feed selected from the following is added to the clarified slurry feed upstream of the hydrotreatment unit (RDS):
a vacuum residue obtained from the vacuum distillation column, preferably hydrotreated,
an atmospheric residue obtained from the atmospheric distillation column, preferably not hydrotreated,
a vacuum distillate obtained from the vacuum distillation column, preferably not hydrotreated;
the feed thus produced after mixing having a BMCI of more than 130 before hydrotreatment, and preferably more than 135.

### Claim 4 (depends on 1)

The process for the production of carbon black according to claim 1 in which, when a RSV feed is added to the clarified slurry feed upstream of the hydrotreatment unit (RDS), the RSV feed is hydrotreated in an ebullated bed unit (HYC) under the following operating conditions:
a pressure in the range 50 to 250 bars, and preferably in the range 60 to 200 bar;
a temperature in the range 300° C. to 550° C., preferably in the range 350° C. to 500° C.;
an HSV in the range 0.1 to 10 h−1, preferably in the range 0.15 to 5.0 h−1;
the catalysts being selected from catalysts comprising an alumina support and at least one metal from group VIII selected from nickel and cobalt, said element from group VIII being used in association with at least one metal from group VIB selected from molybdenum and tungsten.

### Claim 5 (depends on 1)

The process for the production of carbon black according to claim 1, in which a 360+ fraction obtained from coal liquefaction is added to the clarified slurry feed upstream of the hydrotreatment unit (RDS).

### Claim 6 (depends on 1)

The process for the production of carbon black according to claim 1, in which a feed known as steam cracking tar is added to the clarified slurry feed upstream of the hydrotreatment unit (RDS).
