Abstract

The present invention discloses a process for enhancing quality of a hydrocarbon stream. More particularly, the present invention discloses a process for improvement of the combustion quality of a diesel range stream by dissolving an oxygen source in the feed stream before carrying out the oxidation, thereby enhancing the Cetane number, lubricity and reducing emission of the stream. The present invention also discloses a process for enhancing combustion quality of a hydrocarbon stream by carrying out the process in presence of an organometallic catalyst.
