摘要

With the initial wave of ULSD production well established in many areas of the world,rnattention has turned toward maximizing the use of these new assets as well as lookingrnforward to anticipate future requirements. ULSD is an ideal platform for providingrnopportunities to further upgrade diesel quality, since the chemistry/catalysis for cetanernimprovement, aromatics reduction, cold flow improvement, density reduction, biodieselrnprocessing, and conversion can be achieved by applying the right catalyst and processrnsystem. This paper discusses a range of commercially proven options for achievingrnone or more of these additional diesel-upgrading objectives. These solutions canrnsignificantly improve overall refinery economics by leveraging this critical ULSD asset,rnproviding flexibility to upgrade heavier feeds to make more diesel, maximize LCO intornthe on-road diesel pool, and provide capability to process more difficult crudes.
