Abstract
This invention is a method for reducing the particulate emissions tendency of diesel fuel. Also the piston ring sticking, and deposit formation tendency of diesel fuel on the injector and combustion chamber of an internal combustion diesel fuel are reduced. The diesel fuel under the method of this invention is fed to at least one adsorbent bed in which the diesel fuel is contacted with one or more adsorbents under suitable process conditions such that there is a reduction in content of impurities in the fuel which cause the particulate emission causing tendency, piston ring sticking, and deposit formation tendency of the diesel fuel on the injector and/or combustion chamber.
