Abstract (en)
[origin: EP1312661A1] Petroleum feedstocks are treated by ebulliated-bed hydroconversion using a hydroconversion catalyst that is least partly amorphous, and operates with an upward flow of liquid and gas at 30-550 degrees C at 2-35 MPa, an hourly space velocity of 0.1-10 per hour and in the presence of 20-5000 Mn<3> of hydrogen per m<3> feedstock. <??>Treatment of petroleum feedstocks involves ebulliated-bed hydroconversion using a hydroconversion catalyst that is least partly amorphous, and operates with an upward flow of liquid and gas at 30-550 degrees C at 2-35 MPa, an hourly space velocity of 0.1-10 per hour and in the presence of 20-5000 Nm<3> of hydrogen per m<3> feedstock, where the net conversion of products boil below 360 degrees C is 1-80 wt.%; separation from the effluent of a gas that contains hydrogen, hydrogen sulfide and a heavier fraction than the gas soil; hydrotreatment by contact with a catalyst(s) of a distillate fraction(s) and that includes a gas oil fraction at 30-500 degrees C at 2-12 MPa, an hourly space velocity of 0.1-10 per hr and in the presence of 20-5000 Nm<3> of hydrogen per m<3> feedstock; separation of hydrogen, gasses and the gas-oil fraction with a 50 ppm sulfur. The make-up hydrogen is brought to hydrotreatment. At least 80 wt.% of the feedstocks boil above 340 degrees C and contain ≥ 0.005 wt.% sulfur for producing a gas oil fraction with a sulfur of ≤ 50 ppm. <??>An Independent claim is also included for an installation for treatment of petroleum feedstocks comprising a zone (I) for ebulliated-bed hydroconversion of a hydroconversion catalyst and with a pipe (1) for introducing the feedstock to be treated, a pipe (11) for the output of the hydroconverted effluent, a pipe (31) for drawing off catalyst and/or a pipe (32) for supplying fresh catalyst, as well as a pipe (29) for introducing hydrogen where the zone is operated with an upward flow of feedstock and gas; a zone (II) for separation having a separator(s) (3, 6) for separating the hydrogen-rich gas via a pipe (4) for separating the hydrogen sulfide in pipe (7) and obtaining a liquid fraction in pipe (8) and also includes a distillation column (9) for separating a distillate fraction(s) that includes a gas-oil fraction in pipe (11) and a heavy fraction in pipe (10); hydrotreatment zone (III) that contains a fixed bed hydrotreatment catalyst for treating a gas oil with a pipe (30) for introducing make-up hydrogen and a pipe (12) for the output of the hydrotreated effluent; and a separation zone (IV) that includes a separator (13, 16) for separating hydrogen via pipe (14) for separating the hydrogen sulfide in pipe (17) and for separating a gas-oil that has less than 50 ppm via pipe (18).
