Title:

PROCESS FOR THE SELECTIVE HYDRODESULFURIZATION OF OLEFINIC NAPHTHA STREAMS

Document Type and Number:

WIPO Patent Application WO2004003112

Kind Code:

A8

Abstract:

A process for the hydrodesulfurization of cracked olefin streams is described, the process aiming at reducing the sulfur content while at the same time minimizing degree of said olefins. In order to dilute the added reaction hydrogen, the process makes use of non-reactive compounds such as N2, CH4, C2H6, C3H8, C4H10, CO2, group VIII noble gases as well as admixtures of same in any amount, in gas or vapor phase.
