A naphtha hydrotreating process containing a first step in the presence of the first catalyst containing a support; a second step in the presence of the second catalyst containing a support and an active phase, which active phase contains a Group 9 or 10 metal and a Group 6 metal; a third step in the presence of the third catalyst containing a support and an active phase, which active phase contains a Group 6 metal; wherein the content of Group 6 metal of the third catalyst is less than the content of Group 6 metal of the second catalyst; the ratio of the loaded specific surface area of the first catalyst to that of the second catalyst is greater than or equal to 1.20; the ratio of the loaded specific surface area of the third catalyst to that of the second catalyst is greater than 1.07.

Naphtha hydrotreating process

A process for desulfurizing a cracked naphtha containing organic sulfur compounds: The process further includes providing heat to the distillation column by an intermediate reboiler powered with a heat source having a temperature lower than that one of the bottom reboiler.
