Abstract

La presente invención se refiere a un procedimiento para redepurar aceites usados, de manera de producir un aceite de material de base esencialmente equivalente en calidad al material de base virgen, cuyo procedimiento comprende las etapas de a) impregnar termicamente el aceite usado a una temperatura de aproximadamente 259 a 340 grados C durante un tiempo suficiente para llevar al máximo la remoción de fósforo, haluros y precursores de cieno; b) separar el aceite impregnado térmicamente bajo condicones y empleando procedimientos suficientes para eliminar los productos de congerción de baja ebullición a partir del aceite termicamente impregnado, c) destilar el aceite usado termicamente impregnado, separado para producir un destilado y un residuo d) hacer pasar el destinado a través de un lecho de protección de material activaod e) hidrotratar el destilado tratado en lecho de protección bajo condiciones de hidrotratamiento, produciendo de esta manera un material de base redepurado.The present invention relates to a process for re-purifying used oils, so as to produce a base material oil essentially equivalent in quality to the virgin base material, the process comprising the steps of a) thermally impregnating the used oil at a temperature of approximately 259 to 340 degrees C for a time sufficient to maximize removal of phosphorous, halides, and silt precursors; b) separate the thermally impregnated oil under conditions and using sufficient procedures to remove the low boiling freezing products from the thermally impregnated oil, c) distill the separated thermally impregnated used oil to produce a distillate and residue d) pass The one destined through an active material protection bed or e) hydrotreating the treated distillate in a protection bed under hydrotreating conditions, thus producing a re-purified base material.
