摘要： The invention relates to naphtha hydrodesulfurization incorporating either high temperature depressurization or controlled heating for mercaptan removal. More particularly, the invention relates to a naphtha hydrodesulfurization process, wherein the hot naphtha exiting the desulfurization reactor (12) contains mercaptans, most of which are removed without olefin loss, by depressurizing the hot naphtha (14), thermally treating the hot naphtha, or some combination thereof. The desulfurized naphtha may be cooled and condensed to a liquid, separated (16) from the gaseous H2S, stripped and sent to a mogas pool.

摘要： A gasoline blendstock is produced having a decreased amount of sulfur by first selectively hydrodesulfurizing a cracked naphtha that contains both non-mercaptan and mercaptan sulfur to produce a first product having a decreased amount of non-mercaptan sulfur. The mercaptan sulfur in the first product is then converted or removed to obtain a second product having a decreased amount of mercaptan sulfur.

摘要： The invention relates to a method and dual reactor system for hydrotreating a wide cut cat naphtha stream comprising heavy cat naphtha (HCN) and intermediate cat naphtha (ICN). Accordingly, a HCN fraction is hydrotreated under non-selective hydrotreating conditions and an ICN fraction is hydrotreated under selective hydrotreating conditions. The hydrotreated HCN and ICN effluents may be conducted to heat exchangers to pre-heat the ICN feed, obviating the need for a furnace.

摘要： The invention includes a hydrotreating method for increased CO content comprising: contacting an olefinic naphtha feedstream with a hydrogen-containing treat gas stream and a hydrotreating catalyst in a reactor under hydrotreating conditions sufficient to at least partially hydrodesulfurize and/or hydrodenitrogenate the feedstream, wherein the feedstream and the hydrogen-containing treat gas stream collectively have greater than 10 vppm CO content and/or wherein the reactor inlet sees an average CO concentration of greater than 10 vppm, wherein the hydrotreating catalyst comprises a catalyst having cobalt and molybdenum disposed on a silica-based support, and wherein the hydrotreating conditions are selected such that the catalyst has a relative HDS activity at least 10% greater than an identical catalyst under identical conditions except for a collective CO content of the feedstream and/or hydrogen-containing treat gas being

摘要： A high temperature naphtha desulfurization process with reduced olefin saturation employs a partially spent and low metals content hydrodesulfurization catalyst having from 2-40 % the activity of a new catalyst. The catalytic metals preferably include Co and Mo in an atomic ratio of from 0.1 to 1. The catalyst is preferably at least partially regenerable, has less than 500 wppm of a total of one or more of nickel, iron and vanadium and preferably has no more than 12 wt. % catalytic metal calculated as the oxide. This permits selective deep desulfurization, with reduced olefin saturation, low product mercaptan levels and little or need for downstream mercaptan removal.
