More Information
Summary:Recycle of slurry hydrocracked product to a subsequent slurry hydrocracking reactor downstream of a lead slurry hydrocracking reactor produces reduced mesophase and provides better reactor stability as opposed to recycle to the lead slurry hydrocracking reactor. The recycle stream may be a vacuum bottoms stream and/or a slop wax stream from a fractionation column.
