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.
When using shape-selective zeolite-based active ingredient propylene prolific production of highly active additives, curing and FCC FCC primary catalyst in combination, can increase the yield of LPG and propylene. The catalytic additives have a higher selective catalytic activity. It has good abrasion resistance and particle size distributi
