IndianOil 1 R&D in Refinery Processes for Fuel Quality Upgradation R.P. Verma Executive Director Indian Oil Corporation Limited R&D Centre, Faridabad National Workshop Auto Fuel Policy – Way Forward
IndianOil 2 Discussion on …….. Current/future fuel specifications Status & trends in technology for fuel quality upgradation R&D’s role Summary
IndianOil 3 Technologies used in Indian refineries for fuel quality upgradation SULPHUR PLANT TAIL GAS TREATING ACID GAS ISOMERIZATION JET/DIESEL HT JET/DIESEL HT GASOLINE REFORMER GASOLINE JET/DIESEL LN HN JET DIESEL HGO ATMTOWERATMTOWER GASOLINE SR Coker / Visbreaker REFORMER JET/DIESEL HT HCU/FCC LSFO LVGO VACTOWERVACTOWER HCU LCO HVGO VGO HT FCCU FCCG HDT Crude
IndianOil 4 Environmental Regulations Rapid changes in combustion technologies & fuel specifications induced by Legislative bodies Recommendation of Euro / BS specifications for India by Mashelkar Committee
IndianOil 5 Gasoline Specification - Trend * Proposed by World Fuel Charter
IndianOil 6 Effect of Gasoline Specifications on Major Parameters Lower Sulfur content Lower RVP Lower benzene & aromatics Lower olefin content Limited Oxygen content
IndianOil 7 Technologies for Gasoline Reformer (Major technology for MS) Technological / operational change Low pressure operation Change to CCR from SR Pre-fractionation for Benzene Spec Integration with Isomerisation unit FCC (Major technology for MS) Technological / operational change Use of low ‘S’ crude, Hydrocracker bottom/ Hydrotreated feed for ‘S’ spec Use of desulfurisation additives Selective desulfurisation of FCCG Treatment of heart-cut of FCCG in reformer Contd.
IndianOil 8 Technologies for Gasoline (Contd.) Isomerisation Ideal choice for upgrading light naphtha Used for saturation of benzene also Pt on Chlorinated alumina – most active catalyst Zeolite catalyst based technology to be improved (more activity required) Alkylation No unit in India (High LPG demand) Proven technology based upon HF / H2SO4 hazardous Solid acid based process at development / demonstration stage
IndianOil 9 Diesel Specifications - Trend * Proposed by World Fuel Charter
IndianOil 10 Effect of Diesel Specifications on Major Parameters Low sulfur Low aromatics / PAH High cetane number Lower density Lower distillation end point
IndianOil 11 Technologies to meet Diesel specifications DHDS for meeting sulfur specifications Intensive research on DHDS catalyst for improving activity Development of high performance internals High Pressure DHDT/MHC for Cetane improvement Single stage units based upon non-noble metal catalysts MHC an attractive option along with FCC Hydrocracking process for best quality diesel
IndianOil 12 R&D’s role Technologies For Environ-friendly Fuels Tailor-made Catalysts / Additives Technologies For Future Alternate Fuels
IndianOil 13 Technologies For Environ-friendly Fuels Conversion of Naphtha to LPG & MS: Hydrocracking Low pressure process of conversion of naphtha to auto-LPG and high octane, very low S MS component Indalin + Catalytic cracking process for conversion of naphtha to LPG and high-aromatics, low S MS component Treating Process: IndeTreat/IndeSweet Non-dispersive extractive process for desulfurisation of LPG and Naphtha Contd.
IndianOil 14 Technologies For Environ-friendly Fuels (Contd.) DHDS / DHDT Development of Hydroprocessing technology for production of ultra low sulfur and high Cetane diesel Commercialisation at BRPL (with EIL) and at Paradip (with EIL and Shell) Development of high performance DHDS catalyst Hydrodynamic studies & development of reactor internals (with EIL) Adsorptive desulfurisation Reactive adsorption based process for desulfruisation Most suitable as a finishing reactor Isomerisation Development of zeolyte based catalyst (jointly with IIP) Process development
IndianOil 15 Tailor-Made Catalysts / Additives FCC catalysts & additives – Developed & commercialized by Indian Oil Lotus-24 (Catalyst with higher LPG yield) i-Max / Super i-Max (ZSM-5 additive) Hydrocracking catalyst – Developed by Indian Oil IZV (Along with M/s Zeolyst International) – For increase in LPG make (Commercialised) IZN (Naphtha hydrocracking to LPG)
IndianOil 16 Technologies for future Coal/residue/biomass gasification - Production of premium liquid fuels, hydrogen and / or power Reactivity studies for Indian coal, petroleum residue, biomass and combination Pilot plants for feasibility data generation Gas to liquid technologies - High quality middle distillates Development of catalysts Pilot plant studies
IndianOil 17 Technologies for future Bio-oil refining Thermochemical Routes from Biomass to H2 Gasification/Water-Gas Shift Supercritical Steam/Water Conversion Pyrolysis/Steam Reforming Does not require tricky gas clean-up step Processing biomass has nearly zero net CO 2 impact
IndianOil 18 Technologies for future Pyrolysis/Steam Reforming Liquid bio-oil can be pumped and has higher energy volumetric density than biomass Can be processed in distributed systems or at locations with existing hydrogen infrastructure in large-scale centralized reformers (earlier concept) Can be co-processed with traditional fossil feedstocks Biorefinery Integration Produce from residues
IndianOil 19 Alternate Fuels Alternate fuels currently in use CNG LPG Ethanol & Biodiesel Emerging fuels & engine technologies Bio-fuels Hydrogen Electric vehicles Fuel cells Considerable R&D activities in progress on bio-fuels, H2, HCNG, Fuel cells etc.
IndianOil 20 Hydrogen Developments in H2 production from various sources – renewable & non-renewable Environmental benefits realizable with use of H2 as neat fuel or in admixture with CNG in existing IC engines High-energy conversion efficiencies & associated environmental benefits of emerging fuel cell technology National Hydrogen Energy Board prepared an extensive report IOC-R&D the nodal agency for research on Hydrogen fuel
IndianOil 21 Summary Environmental regulations have led to Development in new processes / catalysts Significant enhancement of catalyst performance Re-orientation of technologies Prominence of hydroprocessing Innovative approach & new technologies and willingness to look beyond fossil fuels would sustain the industry in longer term
