Abstract (en)
[origin: EP1700900A1] Improved process of hydrocracking with recycling, having an elimination of polyaromatic compounds of at least a part of the fraction, which is recycled by adsorption on an adsorbent, containing alumina-silica (comprising alumina and silica) by mass content in silica (SiO 2) higher than 5 wt.% and =95 wt.%. Improved process of hydrocracking with recycling, having an elimination of polyaromatic compounds of at least a part of the fraction, which is recycled by adsorption on an adsorbent, containing alumina-silica (comprising alumina and silica) by mass content in silica (SiO 2) higher than 5 wt.% and =95 wt.% with: a sodium content of lower than 0.03 wt.%; a total porous volume, measured by mercury porosimetry, of 0.45-1.2 ml/g; a porosity such as, the volume of the mesovoids with a diameter of 40-150Å and an average porous diameter of 80-140Å at 30-80% of the total porous volume and the volume of the macropores with a diameter higher than 500Å at 20-80% of total porous volume, both measured by mercury porosimetry; a specific Brunauer, Emmett and Teller surface at 200-550 m 2>/g; and a X-rays diffraction diagram, which contains at least the principal lines characteristic of at least one of the transition aluminas comprised in the group composed by aluminas of rho, khi, kappa, eta, gamma, theta and delta.
