Abstract

The gasoline hydrogenating catalyst includes the components of carrier with TiO2 in 20-90 wt%; active component A of VIII metal oxide in 0.1-8 wt%; active component B of VIB metal oxide in 1-13 wt%; and adhesive in the rest content. After being pre-sulfurized, the catalyst of the present invention is used to process FCC gasoline in condition of mild hydrogenation and exhibits very high hydrodesulfurization activity and selectivity. Compared with traditional hydrogenation catalyst, the catalyst of the present invention has less loss of gasoline octane number and higher liquid product yield, up to 99 wt%, in the condition of same hydrodesulfurization level.

Description

Technical field

[0001] The invention relates to a catalyst used in the process of hydrotreating gasoline containing sulfur and olefins and a preparation method thereof. In particular, it relates to a gasoline hydrogenation catalyst and preparation method and its application in desulfurization and olefin reduction. Background technique

[0002] Traditional hydrodesulfurization, olefin saturation and denitrification catalysts are usually porous alumina or contain a small amount of SiO 2 Or B 2 O 3 The alumina is the carrier, and the metal elements of group VIII and VIB are the active components. Another type of hydrodesulfurization, olefin saturation and denitrification catalysts are bifunctional catalysts based on molecular sieves.

[0003] FCC (catalytic cracking) gasoline can reduce the content of organic sulfur and olefins through selective hydroprocessing, so as to meet environmental protection requirements. However, the octane number-barrel loss rate of gasoline after treatme...
