Process for the catalytic dewaxing of more than one precursor derived lubricating base oil refinery.

摘要

PROCEDURE FOR dewaxing Catalytic base oil precursor LUBRICANTS DERIVED FROM MORE THAN ONE REFINERY INCLUDING CONTACT IN A FIRST REACTION ZONE IN THE PRESENCE OF A GAS CONTAINING HYDROGEN CONDITIONS dewaxing, a first feed stream comprising YOUR ONCE A base oil precursor LUBRICANT REFINED DERIVED FROM A FIRST rEFINERY CONTAINING WAX FIRST CONTAINING straight chain paraffins with a first CATALYST DESHIDROPARAFINACION SELECTIVE FOR cONVERSION OF FIRST CERA CITED AND CONTACT IN THE PRESENCE OF A GAS It CONTAINS HYDROGEN IN TERMS OF DESHIDROPARAFINACION IN A second reaction zone PARALLEL PLACED A base oil precursor LUBRICANTS DERIVED FROM A SECOND rEFINERY containing a second WAX COMPOUND OIL branched and / or cyclic with a second CATALYST hydrodewaxing SELECTIVE FOR CONVERSION THE SECOND CERA CIT ADAY OPTIONAL AREAS AND ONE OR MORE OTHER SUBSEQUENT REACTION forerunners like the aforementioned. FINALLY SPLIT END PARALLEL CURRENTS IN TWO EFFLUENT LUBRICANT OILS dewaxed BASES OF THE REFINERY, REACTION ZONES CITED.
