  1. The Recent Development of F-T Technology and its Commercialization in China 中国新一代间接液化技术和产业化发展 孙 启 文 Qiwen Sun Presentation

  2. Fischer- Tropsch ketones/ aldehydes Fischer-Tropsch process Presentation

  3. LTFT Technology Development • Catalysts • －Fe-based catalyst • －Co-based catalyst • Reactors －Slurry bed reactor • well mixed, isothermal • high yield • catalyst loading/unloading on line • minimal differential pressure • flexibility, easy to control and low operating cost • simple structure Presentation

  10. LTFT: major products: diesels, naphtha HTFT: major products: gasoline, diesel, olefins and oxygenates Product selectivity comparison of LTFT and HTFT Comparison of end products from LTFT and HTFT processes Presentation

  11. Product Commercialization of CTL Fischer-Tropsch Technology Main process Steps (1) coal gasification and ASU (2) gas purification and sulphur recovery (3) Fischer-Tropsch synthesis (4) light end recovery (5) tail gas H2 recovery (6) product upgrading (7) reaction water treatment (8) gas turbine using tail gas as fuel (9) power generation using reaction heat generated steam Process diagram for a million ton/ year CTL plant using Fischer-Tropsch Technology Presentation

  12. A super CTL complex with a LTFT capacity of 3 million ton/ year, a HTFT capacity of 2 million ton/ year and a power generation capacity of 300MW using tail gas as gas turbine fuel. The productions of different products are： • Diesel 3280 kton/year • Gasoline 300 kton/year • Olefins 1000 kton/year • Solvent oils 120 kton/year • Speciality wax 50 kton/year • Alcohols 180 kton/year (including methanol, ethanol, propanol, ect. ) • Ketones/ aldehydes 20 kton/year • Acids 50 kton/year Presentation

  13. Prediction on Development of Commercial Fischer-Tropsch Synthesis • 2008–2010, 1 million ton/year demonstration facility • 2015, 5 million ton/year • 2020, 30 million ton/year • Enhance efficiency • Utilization and sequestration of CO2 • More environmentally friendly Presentation
