    Presentation Presentation Presentation Transcript

      • Latest Axens catalysts- Their advantages 
      •   Advances in Hydro treating technology.
      • Properties of Catalyst-
      • Selectivity
      • Stability
      • Specific Surface area
      • Activity
      • Components of Catalyst-
      • Active sites
      • Support/Carrier
      • Promoter
    • Name Application Type Key Features HR 526 Very High Activity HDS for ULSD and VGO Co, Mo, Al2O3
      • Longer cycle length life
      • Minimum hydrogen requirement
      • Specially suited for replacement catalyst for SRGO Hydrotreating units
      HR 538 Ultra Deep HDS & HDN from Naphtha to VGO Ni, Mo, Al2O3
      • Very high Denitrification and Hydrogenation activity
      • Superior Desulfurization activity
      • Used for treating feedstock from Thermal and catalytic cracking
    • Name Application Type Key Features HR 548 Very High Activity for ultra deep HDS and HDN for Diesel and VGO Ni, Mo, Al2O3
      • exceptionally high desulfurization and excellent denitrogenation activities
      • designed to deal troublesome feedstock having
      • high end points
      • high levels of nitrogen
      • cracked materials
      • ideal for cetane and density improvement.
      HR 568 Ultra Deep HDS & HDN from Diesel to VGO Co, Mo Al2O3 with Ni as promoter
      • High HDS and superior HDN activity
      • provides operational feedstock flexibility
      • wide range of operating pressures
      • Limited impact on hydrogen consumption
    • Name Application Type Key Features HR 626 Ultra Deep hydrodesulfurization of distillates Co,Mo oxides on very high purity alumina
      • higher HDN and HDS activity with unique stability
      • Higher HDS activity for ULSD demand
      • SOR conditions better than HR series with superior stability
      • High stability and cost effective life cycle
      • Regeneration by classic ex-situ technique
      HR 945 Hydrogenation of Olefins and Diolefins Ni, Mo, Special Al2O3
      • limits the polymerization of olefins and diolefins
      • Longer cycle operation
    •  
    •  
      • Purpose of Hydrotreatment Process-
      • Diminish air pollution emission
      • Removal of S and N compounds
      • Avoid poisoning of Nobel metal
      • Improve Fuel Quality
      • Various Hydrotreatment processes-
      • Hydrodesulfurization(HDS)
      • Hydrodenitrification(HDN)
      • Hydrodeoxygenation(HDO)
    •   HYDROGEN PARTIAL PRESSURE TEMPERATURE LHSV HYDRODESULFURI-ZATION DENITROGENATION DEOXYGENATION HYDROGENATION OF AROMATICS HYDROCRACKING COKING
      • Deep HDS-
      • Primary goal is to reduce ‘S’ content in finished product
      • Pollution problem.
      • Advances in HDS
      • Catalyst support/carrier
      • carbon, silica-alumina, titania, zirconia,ASA
      • Catalyst active species
      • C0-Mo,Ni-Mo.Pt and Pt-Pd are very active in Deep HDS(sulfur upto 6 ppm) .
      • Mo sulfide has a much higher activity than Co or Ni sulfide. Sulfided CoMo/Al2O3 and NiMo/Al2O3 catalysts have higher catalytic activities than Mo/Al2O3. Co,Ni are referred as promoters.
      • New Reactor system
      • Conventional fixed bed
      • Gas oil and H2 are co currently added.H2S concentration profile
      • is not uniform.
      • Counter current operation
      • Gasoil from top,H2 from bottom.H2S removed from top
      • Commercial is SynSat Technology (Scheme 1.2)
