Removal of sulfur compounds from hydrocarbon feedstreams using cobalt containing adsorbents in the substantial absence of hydrogen

The process of claim 12 wherein said hydrocarbon stream is contacted with said adsorbent at a temperature from about 10° C. to about 100° C.

A process for removing sulfur compounds from sulfur compound-containing naphtha streams, which process comprises contacting the sulfur compound-containing naphtha stream, in the substantial absence of added hydrogen, with an adsorbent comprised of Co and at least one Group VI metal selected from Mo and W on an inorganic refractory support under conditions that include temperatures from about 10° C. to about 150° C.

A process for removing sulfur compounds from sulfur compound-containing naphtha streams, which process comprises contacting the sulfur compound-containing naphtha stream, in the substantial absence of added hydrogen, with an adsorbent comprised of Co and at least one Group VI metal selected from Mo and W on an inorganic refractory support under conditions that include temperatures from about 10° C. to about 150° C., wherein said adsorbent was preconditioned with hydrogen.

A process for removing sulfur from sulfur compound-containing naphtha streams, which process comprises:

• (a) hydrodesulfurizing said naphtha stream, which contains olefins and sulfur in the form of organic sulfur compounds, to form a hydrodesulfurization effluent at an initial temperature, the hydrodesulfurization effluent comprising a hot mixture of sulfur reduced naphtha at an initial pressure, H2S and mercaptans, and then
• (b) contacting said mixture with an adsorbent comprised of Co and at least one Group VI metal selected from Mo and W on an inorganic support under conditions that include temperatures up to about 150° C., in the substantial absence of added hydrogen.
