1. Application and performance
FCC naphtha hydrogenation catalysts can be used for the selective
hydro desulfurization of catalytic cracking full fraction or heavy
fraction of naphtha/gasoline. For the hydrogenation of heavy
fraction, the first process in fractional distillation, cut it into
light and heavy two fractions. The full fraction or heavy component
processing to selective hydro desulfurization, then the heavy
component separated with Hydrogen gas by condensation and cooling,
liquid phase product processing to steam stripping of non-alkali
deodorization process, turn out to gasoline component in low sulfur
content, and produce finished gasoline product after blended with
other gas components, FCC gasoline selective hydro desulfurization
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.

3. Technology Features
We have developed a new filling technology apply to selective
hydro-desulfurization special catalyst and Catalyst Combination,
select the suitable selective hydro desulfurization process
conditions, under low reaction pressure and high space velocity,
this catalyst works with outstanding sulfur removal capacity, with
low hydrogen consumption and small octane loss ratio.
4. Performance Index
For the sulfur content of FCC gasoline raw material
>450µg/g,olefin content 24~29%, the product sulfur content
<20µg/g,the saturation of olefin <15%,the loss of RON <1.5
unit.
