Transcription

1 Sustainable production of cellulosic ethanol from agricultural residues Advanced Biofuels Leadership Conference 2012 April 3, 2012 Washington, D.C. U.S.A. Martin A. Mitchell Business Development Manager, Americas Süd-Chemie AG A Clariant Group Company

2 Agenda - Süd-Chemie Introduction - Green Strategy of Süd-Chemie - Technology and Development Status - Cellulosic ethanol and beyond

3 Süd-Chemie: developing future-oriented products for more than 150 years : Founding of BAG (now Süd-Chemie AG) in Heufeld; founding shareholder: Justus von Liebig Fertiliser 1906: Bleaching earth and bentonite products Bleaching earth/bentonite 1962: Start of catalyst business 1970: Production of foundry chemicals based on bentonite Catalysts Foundry chemicals 1996: Entry into pharmaceutical protection packaging and water treatment business Manufacturer of Cleantech products: Biocatalysts Exhaust gas purification catalysts Lithium ion battery materials CTL/GTL catalysts

4 Süd-Chemie Worldwide Sales: USD$1.8 billion Employees: 6,400 Süd-Chemie AG is a worldwide operating company with over 80 sites on all continents and major markets of the world With over 30 research facilities worldwide, Süd-Chemie commits major resources for research and development for new innovative technologies All biotechnology activities are currently based in Germany (Munich and Straubing) Clariant (Basel, Swizerland) a top 50 world chemical company aquired Sud-Chemie in 1Q 2011

5 Rationale for Cellulosic Biofuels and Biorenewable Chemicals Market needs and limitation of fossil resources The world is just at the beginning of a dramatic turn of the petroleum era! Peak-oil predictions:

6 The green strategy of Süd-Chemie Renewable feedstocks are the basis for a bio-based economy Biocatalysis offers sustainable conversion to biofuels and bio-based chemicals Süd-Chemie s technology know how for turn-key bioprocesses for bio-refineries Süd-Chemie is one of the few technology development companies in the industry with process & enzyme development under one roof

7 The way to competitive cellulosic ethanol From one company the customer receives a complete integrated process manufacturing solution from pre-treatment to final product Key Technology Features On-site integrated enzyme production Feedstock specific enzyme development C 6 and C 5 fermentation Energy saving ethanol separation

8 World Class Screening Technology Own enzyme production and own enzyme optimization Enzymes are optimized for specific reaction conditions and feedstock Throughput of several 100,000 samples per day >90% conversion of cellulose by proprietary enzymes

9 Process integrated enzymes production are key for low production costs Off-site, At-Site or Hub-solution: C- source minerals, etc. Cellulase Production Utilities Purification, Stabilization, Storage? Handling, Storage? Feedstock Pretreatment Hydrolysis Fermentation Product Isolation Ethanol Process integrated: minerals, etc. Cellulase Production Feedstock Pretreatment Hydrolysis Fermentation Product Isolation Ethanol

10 Feedstock specific enzymes Advantages: Higher yields with optimized enzymes Feedstock specific enzymes Optimized enzymes Lowest enzyme costs Process integrated enzyme production Independent from third party enzyme suppliers

11 C 6 and C 5 fermentation - conversion of all sugars to ethanol Proprietary yeast developed by Süd-Chemie Simultaneous conversion of all sugars to ethanol One-Pot-Reaction, patented process Cellulose Biogas Rest Ethanol Energie Lignin Hemicellulose 50% higher product yield Cellulosic Ethanol

12 Energy consumption Low energy consumption in DSP 120% 100% 80% 60% 40% New ethanol separation process with very low energy consumption. Based on Süd-Chemie technology Patented process and material 20% 0% Standard DSP 2G SC Technology SC Technology optimized With the innovative Süd-Chemie separation process up to 50% of energy can be saved in DSP.

13 Challenges for Cellulosic Ethanol Production Technology challenges Challenges addressed with High process yields All sugars to ethanol Feedstock specific reaction conditions Feedstock optimized enzymes Low operating costs Low investment costs Sustainable process Integrated enzyme production No external energy required Proprietary ethanol separation process Proven (bio)chemical process technology All scalable to production scale No Food-or-Feed issue Ethanol is nearly Carbon neutral Process is energy self sufficient

14 Commercial development and status Pilot Plant: In operation since 1Q 2009 Demonstration Plant: In commissioning. Begin operation 2Q 2012 (330,000 gal/yr) Production Plant: Partnering is on-going Production Plant Engineering studies completed: process integration in production scale, equipment design & specification, energy integration

15 Business model of Süd-Chemie AG for commercialization Süd-Chemie will offer sunliquid -process licenses to interested parties. A sunliquid license includes: Integrated process technology package including proprietary, energy saving ethanol separation technology Starter cultures for process integrated production of enzymes Starter cultures for the proprietary fermentation organism which converts C 5 and C 6 to ethanol

16 Next steps: There s more! -> C 2 Platform Ethylene Oxide/Ethylene Glycol Technology Awarded ~ 80% of non-captive licenses since 1980 (30 awards since 1990) Licenses other EO derivative technologies Alcohol Dehydration Technology Awarded 2 ethanol-to-ethylene and 6 ethanol to EO/EG licenses since 2006 Expanding technology to butanols

17 Next steps: There s more! Cn-platform concept Hemicellulose Cellulose Lignin Energy Lignocellulose Feedstock C n -Chemistry Process and product examples, conceptual presentation
