Prehydrotreating Catalyst for Reforming Feedstocks
h@hydrogenationcatalyst.com
-1. Introduction
Pre-hydrotreating catalyst (PH-1) is used for processing catalytic reforming feedstock, etc. The catalyst can be used for hydrofining light distillates that are from straight-run or secondary processing phases
-2. Product Characteristics
Pre-hydrotreating catalyst (PH-1) is high in activity for desulfurization and denitrogenation and low in activity for olefin saturation, has high crushing strength and thermal stability, and can be regenerated easily.
-3. Chemical Composition
NiO, MoO3, CoO, alumina.
