Catalysts for hydrotreating and hydrocracking processes ensure the removal of sulfur, nitrogen, and aromatic compounds, while improving diesel fuel quality (cetane number, cold flow properties) and converting heavy fractions into lighter cuts, thereby increasing clean product yields and overall refining efficiency.
Hydrotreating Catalysts
- For catalytic reforming and isomerization unit feedstocks (NHT)
- For fluid catalytic cracking (FCC) gasoline (NHT)
- For kerosene (KHT)
- For diesel fuel (DHT)
- For vacuum gas oil (VGO HT)
- Guard bed catalysts
Hydrocracking Catalysts (HCC)
- Fixed-bed (single-stage and two-stage processes)
- Moving-bed processes
Dewaxing Catalysts
- Catalytic dewaxing (DWX)
- Isodewaxing (Iso-DWX)
Key Tasks
- Hydrodesulfurization — HDS
- Hydrodenitrogenation — HDN
- Hydrodearomatization — HDA
- Density reduction / Volume swell
- Upgrade of diesel fuel cetane number
- Conversion of heavy cuts into clean products (improving refinery economics)
- Improvement of diesel fuel cold flow properties
Selection Specifics
We design the system based on the client’s specifications (objectives, raw materials, equipment configuration, operating mode).
