Werkwijze voor het omzetten van was-achtige voedingen in zware basisolie met weinig waasvorming.

摘要

The present invention discloses a process for producing a low haze heavy base oil including the steps of: (a) providing a heavy waxy feed stream having an initial boiling point greater than 900° F. and having a paraffin content of at least 80%; (b) separating the heavy feed stream into a heavy fraction and a light fraction by a deep cut distillation; and (c) hydroisomerizing the light fraction to produce a low haze heavy base oil.
