摘要

"The process flexu00ecvel improved production bases, Oils and middle distillates with a conversion hidroisomerizau00e7u00e3o followed by a dewaxing catalu00ectica".The present invention relates to a process for the simultaneous production of improved base oil of high quality and high quality middle distillates.A process comprising successive steps of hidroisomerizau00e7u00e3o and catalytic dewaxing.The step of hidroisomerizau00e7u00e3o is carried out in the presence of catalysts containing at least one noble metal deposited on an amorphous acid medium, the dispersion of metal being from 20 to 100%.The support is preferably an amorphous silica alumina support.The catalytic dewaxing step is carried out in the presence of catalysts containing at least one element of hydro - desidrogenante (Group VIII) and at least one molecular sieve.Chosen from among warmth - 30, I 2 and I - 11.
