Title: Cleaner Coal Technologies


1
Cleaner Coal Technologies Theo L.K.
Lee Hydrocarbon Technologies, Inc. (A Wholly
Owned Subsidy of Headwaters Corporation) June
10, 2003 Woodrow Wilson International Center
2
Headwaters Corporation
  • Utah based alternate fuels company
  • NASDAQ symbol HDWR
  • 28 million shares _at_ 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

3
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)

4
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..

5
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

6
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.

World Proved Recoverable Coal Reserves World
Energy Council (Jan 2001) million short tons
8
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

9
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 HTIs COAL PROCESS
  • Feasibility study for an India client
  • Other potential sites under consideration
  • Indonesia, Yunnan Shaanxi (China), Australia,
    etc..

10
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
  • Shenhuas Pioneer Plant
  • Direct Coal Liquefaction technology
  • 60,000 BPD or 20 million BPY (15,000 TPD or 4.5
    million tons/y)
  • Investment cost US2.0 to 2.2 billion
  • ROI of 12 to 15
  • 1st Q 2006 Startup

11
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.
