Abstract:
Processes for desulfurizing a fluid catalytic cracker (FCC) naphtha feedstock, straight run naphtha feedstocks and combinations thereof are provided herein. Naphtha boiling range feed is passed over a silicon trap prior to being hydrodesulfurized in an olefin-retentive, catalytic naphtha hydrodesulfurization process. Processes for removing silicon from FCC naphtha feedstock, straight run naphtha feedstock and combinations thereof are also provided herein.

Claim (Index 14):
The process of  claim 1 , wherein the hydrodesulfurization is performed in a two stage process comprising:\n (i) contacting the naphtha boiling range effluent with hydrogen and a hydrotreating catalyst in a first vapor reaction stage to remove at least about 70 wt % of sulfur present in the naphtha boiling range effluent to produce a first stage effluent comprising a mixture of reduced sulfur naphtha and H 2 S; and separating the reduced sulfur naphtha and H 2 S; and (ii) contacting the reduced sulfur naphtha and hydrogen with a hydrodesulfurization catalyst in a second vapor reaction stage having a temperature at least about 10\u00b0 C. greater than in the first vapor reaction stage and a space velocity at least about 1.5 times greater than in the first vapor reaction stage to remove at least about 80 wt % of remaining sulfur from the reduced sulfur naphtha to form a desulfurized naphtha product.
