Abstract:
1. A process for the hydrodesulfurization of gasoline, the process comprising: feeding (1) a cracked naphtha containing mercaptans and other organic sulfur compounds and (2) hydrogen to a hydrodesulfurization reactor containing one or more beds of a hydrodesulfurization catalyst; contacting sulfur compounds comprising the other organic sulfur compounds in the cracked naphtha with hydrogen in the presence of a hydrodesulfurization catalyst to convert a portion of the other organic sulfur compounds to hydrogen sulfide; withdrawing from the hydrodesulfurization reactor an effluent comprising hydrocarbons, hydrogen sulfide, and optionally hydrogen; feeding the effluent to a membrane separation system containing a membrane for separating at least a portion of the hydrogen sulfide from the hydrocarbons to recover a hydrocarbon fraction having a reduced hydrogen sulfide content.
