PROCESS FOR RECYCLING AN ACTIVE SLURRY CATALYST COMPOSITION IN HEAVY OIL UPGRADING

摘要

The instant invention is directed to a process employing slurry catalyst compositions in the upgrading of heavy oils. The slurry catalyst composition is not permitted to settle, which would result in possible deactivation. The slurry is recycled to an upgrading reactor for repeated use and products require no further separation procedures for catalyst removal.
