Brief

Hydrodesulfurization Catalyst: 1).low reaction pressure , 2). high space velocity, 3). low hydrogen consumption , 4). small octane ratio.

Detail Description

1. Application

FCC gasoline selective Hydrodesulfurization Catalyst is developed according to FCC gasoline features of high sulfur and high olefin, basis on urgent demand of car oil quality, which make sulfur content in FCC gasoline meet standard of Europe III, Europe IV and Europe V, olefins saturation rate 5%~15%, Octane (RON) 0.3~1.5 unit.

2. Technology Features

We recommend our new developed loading method; under suitable technological condition, low reaction pressure and high space velocity, this Hydrodesulfurization Catalyst works with outstanding sulfur removal capacity, low hydrogen consumption and small octane ratio.
