Abstract (en)
[origin: EP1700899A1] 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 an average porous diameter, measured by mercury porosimetry, of 20-140 Å, a total porous volume, measured by mercury and nitrogen porosimetry, at 0.1-0.5 ml/g, a specific Brunauer, Emmett and Teller surface at 200-600 m 2>/g, a porous volume, measured by mercury porosimetry, comprised in the pores of diameter higher than 140 Å, 160 Å, 200 Å and 500 Å, lower than 0.1 ml/g, 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, and a compressed filling density higher than 0.75 g/cm 3>.
