摘要：
Processes are provided for using employing lower activity hydrodesulfurization catalysts while achieving a desired product sulfur content. After determining effective reaction conditions for hydrodesulfurization using a reference catalyst system, an upstream portion of the catalyst system can be replaced with a lower activity upstream portion. The process allows tailored product sulfur levels to be achieved using reaction conditions similar to those for the reference catalyst system.
