Title:
炭素酸化物耐性触媒を利用する水素処理方法
Document Type and Number:
Japanese Patent JP2014511914
Kind Code:
A
Abstract:
The invention relates to a hydrotreating method for increased CO content comprising: contacting a first olefinic naphtha feedstream with a first hydrogen-containing treat gas stream in the presence of a first hydrotreating catalyst in a first hydrotreating reactor under first hydrotreating conditions sufficient to at least partially hydrodesulfurize and/or hydrodenitrogenate the first olefinic naphtha feedstream to produce a first hydrotreated olefinic naphtha product stream; and contacting the first hydrotreated olefinic naphtha product stream with a second hydrotreating catalyst, wherein the first hydrotreating catalyst and the second hydrotreating catalyst are in a stacked configuration within the first hydrotreating reactor such that the first hydrotreated olefinic naphtha product stream contacts the second hydrotreating catalyst to produce a second hydrotreated olefinic naphtha product stream which is withdrawn from the first hydrotreating reactor, wherein the first olefinic naphtha feedstream and the first hydrogen-containing treat gas stream collectively have a carbon monoxide content of greater than 10 vppm; and wherein the first hydrotreating catalyst comprises cobalt and molybdenum disposed on a silica-based support.
