1 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

2 IndianOil 2 Discussion on ……..  Current/future fuel specifications  Status & trends in technology for fuel quality upgradation  R&D’s role  Summary

3 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

4 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

5 IndianOil 5 Gasoline Specification - Trend * Proposed by World Fuel Charter

6 IndianOil 6 Effect of Gasoline Specifications on Major Parameters  Lower Sulfur content  Lower RVP  Lower benzene & aromatics  Lower olefin content  Limited Oxygen content

7 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.

8 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

9 IndianOil 9 Diesel Specifications - Trend * Proposed by World Fuel Charter

10 IndianOil 10 Effect of Diesel Specifications on Major Parameters  Low sulfur  Low aromatics / PAH  High cetane number  Lower density  Lower distillation end point

11 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

12 IndianOil 12 R&D’s role  Technologies For Environ-friendly Fuels  Tailor-made Catalysts / Additives  Technologies For Future  Alternate Fuels

13 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.

14 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

15 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)

16 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

17 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

18 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

19 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.

20 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

21 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
