HYDROCONVERSION OF HEAVY CRUDES WITH HIGH METAL AND ASPHALTENE CONTENT IN THE PRESENCE OF SOLUBE METALLIC COMPOUNDS AND WATER VAPOR

摘要

The present invention relates to a method of improvement of heavy crudes by hydro conversion at high temperatures in the presence of low cost metallic compounds, soluble in the heavy crude and water, as inhibitors of the formation of coke, followed by a deasphaltization phase for the recovery of the organometallics and its subsequent recirculation in the hydro conversion phase. The method is applicable particularly to batches with high metal and asphaltene contents, like a heavy crude or its vacuum residue.
