UPGRADING INFERIOR RESIDUE TO PRODUCE LIGHT OIL IN A PRE-TREATING PROCESS

摘要

Pretreating inferior residues to provide feedstock with trace metals and a few asphaltenes for downstream processes is important for refineries to process heavier crude oils. Toward this end, the upgrading of vacuum residue (VR) by fluid thermo-cata-contacting conversion (FTC) was investigated on a technical pilot scale riser apparatus.
