10 Coal to Liquids Fischer-Tropsch Technology GTL.F1 AG The Company A Limited Company Under Swiss Jurisdiction Founded in 2005 Shareholders PetroSA and Lurgi GmbH Works With Air Liquide Global Engineering & Construction Solutions The Technologies GTL.F1 Owns the Fisher-Tropsch Slurry Bubble Column Technology and Catalyst IP An Advanced Slurry Bubble Column Reactor Concept With Proprietary Cobalt Catalyst Focus To Market The Entire F-T Concept Based on: All Syngas Production Technologies (Gas or Coal or Biomass Based) Proprietary F-T Technology Integrating Upgrading Technology From a Third Party Link to Air Liquide Global E&C Solutions Technologies Air Separation Units, Hydrogen Units and Purification Technologies Such as Cold Boxes, Membranes, PSAs and Tail Gas Recovery

11 Coal to Liquids GTL.F1 AG Services Offered Studies Usually the First Stage of an Project Development Process Licensing of Technology (i.e.) Licensor Design Package Supply of Proprietary Equipment Supply of Proprietary Cobalt Catalyst Engineering Plant Commissioning, Training, Start-Up Support Technology Support Dissemination of Improvements Development of Processes World s Largest Demomstration Plant for Cobalt Slurry Bubble Column Reactor Operation Plant Operations Support Services (Through PetroSA)

12 Coal to Liquids Product Slate Dictates Technology Choice! Technology Choice is Dictated by the Product Slate What Market is Desired? Regional Product Demand and Pricing? What Are the Product Specifications for the Product Slate? Company Focus? Low Temperature Process Benchmark - Cobalt or Iron Catalyst Based Three Reactor Configurations Exist - Fixed Bed, Slurry Bubble Column and Micro-channel LPG ~ 5% Naphtha 15 20% Middle Distillates 75 80% 12

13 Coal to Liquids Reactor Technologies GTL.F1 (Slurry Bubble Column) Tubular Fixed Bed Reactor Small Maximum Capacity Lower Productivity / Volume Construction PoorerHeat Transfer / Temp. Gradients Pressure Drop Scale Up Slurry Bubble Column Reactor Higher Maximum Capacity Higher Productivity / Volume Easier Construction Good Heat Transfer Pressure Drop Scale Up Catalyst / Wax Separation Espinoza 13

14 Fischer-Tropsch Development Activities - Invested Largest Semi-Commercial Unit in the World Mossel Bay, South Africa, With PetroSA and Statoil Semi-Commercial Operational Between 2004 and Testing Programs With Six Month Runs Obtained Reactor Diameter Structural Height Foot Print Operation 2.7 Meters 40 Meters 25 X 40 Meters Up to 1000 B/D What Was Developed Development of SU and SD Procedures Handling of Catalyst Slurry Determination of Hydrodynamic Parameters Verification of Product Yields Verification of Long Term Catalyst Activity Optimization of the Product Recovery System (Oil and Water)

16 Coal to Liquids Process Integration Benefits Process Integration is Important for Optimizing Plant CAPEX, OPEX and Product Slate Most Capital Intensive Process Gasification and Syngas Treatment Required to Deal With Feedstock. Considerable Integration Potential Between Units Reduces CAPEX Improved Reliability / Availability Can be Designed With Appropriate Buffers and Storage Units Product Slate Can Also Include: Power, Steam, CO2, Sulphur, and Industrial Gases CTL Plant % of Total CAPEX Gasification Gas Treat F-T Upgrading 20 30% 10 15% 15 25% Offsites and Utilities 30 40% 10 15%

17 Coal to Liquids Project and Market Issues Unknowns? Technology Application Operations? Customer(s) Environmental CO2 and Water Pollution Execution High Crude & Product Pricing Low Feedstock Cost (Coal) CAPEX Significant Project Uncertainties Financing Terms & Conditions Feedstock / Natural Gas Competition Government Support Energy Diversification Feedstock Reserves Uncertainty Syndication, Pricing 17

18 Coal to Liquids F-T Overview F-T Technology Based on Slurry Reactor and Cobalt Catalyst is the Benchmark Suitable for GTL, BTL, and CTL Based Projects Slurry Bubble Column Technology Demonstration in a Large Scale is Essential Air Liquide Global Engineering & Construction Solutions and GTL.F1 Can Provide Performance Guarantees, Facilitating Bankability Our Semi-Commercial Demonstration Plant Many Challenges Solved During Testing Programs Lessons Learned Incorporated Within Commercial Designs Process Suitable for Medium and Large Projects Modularization - To Meet Project Constraints Usually a Construction Issue Optimization of Different Processes Required CAPEX and OPEX Reduction Results Air Liquide Global Engineering & Construction Solutions With GTL.F1 : Provides One Interface for All Required Technologies - Improving Design, Process Guarantees and Ensuring Project Viability 18

19 Coal to Liquids Conclusion Coal to Liquids Projects Are Technologically Feasible. Are Complex Require Significant CAPEX Operational Experience is Needed on the Whole Plant and. We Have Not Discussed Carbon Dioxide Emission Issues Fixed Bed Dry Bottom Gasification is Proven and Operating Fischer Tropsch Slurry Bubble Bed Technology Is Available Integration Within the Units and Within the Gasification Process is a Top Priority Will Work With FBDB Technology and With All Other Gasification Processes Air Liquide Can Provide a One Stop Shop for All Technologies Required Integration of Processes and Utilities and Offsites (Water, Etc.) Important. CTL Projects Can be Strategic and Profitable - Opportunities Exist, Especially for Medium to Large Capacities 19
