Cleaner Coal Technologies Theo L.K. Lee Hydrocarbon Technologies, Inc. (A Wholly Owned Subsidy of Headwaters Corporation) June 10, 2003 Woodrow Wilson International Center
Headwaters Corporation • Utah based alternate fuels company • NASDAQ: symbol “HDWR”; • 28 million shares @ $19.50/share • Subsidies: • Covol Fuel: alternate fuels • ISG: bottom and fly ash • Headwaters Technology Innovation Group • Hydrocarbon Technologies, Inc.: energy • Headwaters NanoKinetix: nano-catalysis
R &D Directions • Improving chemical synthesis/reactions via nano-catalysis • Developing cost effect technologies for processing low grade feedstocks, for example • coal • Petroleum residuum (bottom of the barrel)
Nano-catalysis • Nano-dispersion and atomic alignment techniques • Significant saving in precious metals usage • Breakthrough applications • Much simplified and energy efficient process • Examples: • Highly selective catalyst for direct synthesis of H2O2 • Efficient & stable catalysts for fuel cells (DMFC), catalytic converters, etc..
Crystal Phase Controlled Catalyst • Nano-scale deposition technology: • Aligning, spacing and adhering precious metal atoms on support materials. • Controlled spacing between lines of Pd atoms to consistently expose the preferred crystal face (110). • Nearly 100% selectivity for H2O2 ; no byproduct (H2O) H/O = 1/1 3/1 4/1
Alignment of Pd Particles • Princeton University Materials Institute high resolution transmission electron microscope image. • Illustrates highly organized and efficient structure of HTI nano-catalyst. • Parallel lines are rows of palladium atoms on support material. • Verifies consistent exposure of (110) crystal face and spacing between lines of atoms necessary to achieve 100% selectivity for H2O2. 3 nm
World Proved Recoverable Coal Reserves World Energy Council (Jan 2001) – million short tons
Coal to Liquids • Direct Coal Liquefaction (DCL) products: • Higher diesel to gasoline ratio than petroleum derived • Use existing refining techniques • Meet all current & projected specifications for sulfur and aromatics required • Indirect Coal Liquefaction (IDCL) products: • Less energy efficient • Ultra clean diesels with no sulfur or nitrogen • No aromatic; high cetane number ( over 75) • Integrated DCL and IDCL plant
Direct Coal Liquefaction • A clean coal technology • US DOE funded development between mid-70s & late 90s. • Japanese DCL program completed in late 90s • Significant technology improvements and cost reduction • China is constructing a pioneer commercial plant in Inner Mongolia; utilizing HTI’s COAL PROCESS • Feasibility study for an India client • Other potential sites under consideration: • Indonesia, Yunnan & Shaanxi (China), Australia, etc..
The Shenhua Project (Inner Mongolia) • China imported 500 million barrels of crude oils in 2001. • Energy security and self sufficiency • Huge coal resources ; Shenhua coalfield (236 billion metric tons proven reserves) • Estimated 10 plants to be constructed in the next 20 years in China • Shenhua’s Pioneer Plant: • Direct Coal Liquefaction technology • 60,000 BPD or 20 million BPY (15,000 TPD or 4.5 million tons/y) • Investment cost: US$2.0 to 2.2 billion • ROI of 12 to 15% • 1st Q 2006 Startup
Concluding Remarks • U.S. recoverable coal reserve is 273 billion short tons • 90 billion tons minable by surface mining • Coal conversion technologies are matured for commercial consideration • Coal liquefaction technologies produce clean fuels • Low or no S, N, & aromatics; no ash • Carbon dioxide can be effectively recovered at the coal conversion facilities • Lesser reliance on foreign oils and addressing energy security issue.
