METHOD OF UPGRADING RESIDUA |
摘要 |
Residua comprises upgraded by first partitioning a hydrocracked residua into a vapor fraction and a liquid fraction. The vapor fraction is hydrotreated forming a first hydrotreated product. The liquid fraction is partitioned into a residua fraction and a light liquid fraction. The light liquid fraction can be hydrotreated or hydrocracked to form a hydroprocessed product. The hydrotreated product and the hydroprocessed product are then combined forming a substantially upgraded synthetic crude product refinable as a routine crude in a refinery into products that meet stringent specifications. In particular, residua can be upgraded to make a quality jet fuel fraction and a naphtha fraction containing less than 1 ppmw sulfur and nitrogen.
