Principles For Selection Of Cationic Adsorbents For The Selective Removal Of Sulfur-Containing Compounds From Diesel

Patent Status

Brief Description

A major challenge facing petroleum refiners is the desulfurization of diesel where sulfur levels must be reduced to less than 10 ppm.  This is difficult because alkyl groups inhibit access to the sulfur atom.  Furthermore, it requires high hydrogenation under great pressures.

 This invention provides an alternative to hydrodesulfurization by the adsorption of thiophene derivatives on a solid adsorbent.  It is a method for predicting selective performance of an adsorbent from a list of metals or cations for use in removing contaminants as thiophene derivatives in a hydrocarbon feed.

Suggested uses

Removal of thiophene derivatives from hydro-carbon products, e.g., vacuum gas oils, kerosene and diesel fuels.

Advantages

Cheaper and more efficient.
