Abstract
The present invention relates to a process for the pretreatment of heavy oils using a catalytic hydrotreating process prior to introduction to a refinery. More specifically, the invention relates to the use of an HDM reactor and an HDS reactor in order to improve the characteristics of the heavy oil, such that when the oil is introduced into the refinery, the refinery can achieve improved throughputs, increased catalysts life, increased life cycles, and a reduction in overall operation costs.
