摘要

"The process flexu00ecvel improved production of oils and distillates by a base conversion in a catalyst hidroisomerizau00e7u00e3o little scattered followed by a dewaxing catalu00ectica".The invention relates to a process, improved production of base oils of very high quality and of simultaneous production of middle distillates with high quality.That includes the successive steps of hidroisomerizau00e7u00e3o and catalytic dewaxing.The hidroisomerizau00e7u00e3o unfolds in the presence of a catalyst which contains at least one noble metal deposited on an amorphous acid medium, the dispersion in the noble metal being less than 20%.Preferably the carrier is an amorphous silica alumina.The catalytic dewaxing unfolds in the presence of a catalyst which contains at least one element hidrodesidrogenante (Group VIII) and at least one molecular sieve selected among ZBM - 30.I 2 and I - 11.
