PROCESS FOR QUALITY ENHANCEMENT IN HYDROCARBON STREAM

摘要

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.

主权项

1. A process for increasing cetane number of a diesel range stream, the process comprising:
(a) providing a feed diesel range stream, with a sulfur content of less than 350 ppmw and a cetane number, (b) saturating said diesel range stream with an oxygen source, and (c) subjecting said oxygen source saturated diesel range stream to oxidation at a pressure of about 1 to 50 barg, to obtain oxidized diesel range stream with increased cetane number relative to the feed diesel range stream, wherein the saturated diesel range stream contains at least a portion of oxygen source in dissolved form during oxidation.
