摘要
An improved method is described for presulfiding and preconditioning a residuum hydrotreating or hydrocracking catalyst as an integrated part of the hydroconversion process in which catalyst is added on-stream intermittently or continuously without interruption of the hydroconversion process. The method is used to condition, activate, or presulfide fresh or regenerated catalyst prior to its addition to the hydroconversion reactor utilizing product streams from the hydroconversion process.
