Coal21st: Economic Benefits High value chemicals produced: primarily benzene with some toluene and xylene (BTX) for chemical processing facilities. Benzene is a raw material for production of phenol, malic acid, caprolactam, alkylbenzene, styrene, and dye stuff intermediates. Toluene (Methylbenzene) is a Solvent for paint and rubber, and Raw material for toluene di-isocyanate, benzoic acid, and dye stuff intermediate. Xylene is solvent for paint and insecticide, and raw material for paraxylene, orthoxylene, and ethylbenzene Naphtha as N-dodecane with boiling point (bp) of F Fuel Oil as N-pentadecane with bp of F Other oils like thiophene with some sulfur (bp F) pyrrole with some nitrogen (bp F), heavy oils like chrysene (bp F) Low sulfur diesel, methanol, or other chemicals from residue syngas. Low sulfur, low nitrogen, high Btu solid fuel-Char
Why ACTs Coal 21 st Coal Refining Process? Highest throughput (lowest residence time 0.1 to 3.0 seconds) of all synfuels process resulting in lowest capital cost (HDP should be factor of >10 times cheaper than equivalent sized gasifier with residence times in the minutes). Coal 21 st maximizes yield of high value aromatics as BTX plus naphtha and fuel oils (can be used directly or refined further into diesel fuel, gasoline) Low emissions of CO2 as BTX when converted primarily into paint and plastics traps about 8% of the carbon. Low emission diesel (LED) has a Cetane number of 78, twice that of conventional diesel. This increases miles per gallon and reduces CO2 another 0.7%. The result is a total potential reduction of about 8.7% over burning the coal for electricity. Potential to be a more flexible and robust design with possible recycle of aromatics, steam reforming of aromatics into syngas, conversion of syngas into multiple products Low sulfur solid fuel (char) produced as compliance solid fuel for existing and new coal fired power plants High Return on Equity (24% for 100 tpd to 232% for 30,000 tpd) is possible due to the low cost of the HDP, high throughput. (assuming $30 per ton for coal and > $250 per ton for products).
Coal21st Societal & Environmental Benefits Twenty 30,000 tpd Coal21st Coal Refineries would generate char for 25,000 MW of clean power and produce 640,000 bbl/day of very low sulfur liquids thereby decreasing dependence on imported or domestic oil. Burning char instead of coal reduces SOx (>85%) and NOx (65%), toxics (mercury, chlorine, etc. total), particulates ( microns) without flue gas desulfurization for SOx or SCR for NOx Low emissions of CO2 as BTX when converted primarily into paint and plastics traps about 8% of the carbon. Low emission diesel (LED) has a Cetane number of 78, twice that of conventional diesel. This increases miles per gallon and reduces CO2 another 0.7%. The result is a total potential reduction of about 8.7% over burning the coal for electricity. Syngas produced by Fisher-Tropsch (FT) yields low emission diesel (LED) with 1 ppm sulfur (exceeds new EPA standards) plus low sulfur naphtha and high value lubricants. Coal refineries can use any local, poor quality, high cost coals (insensitive to coal prices). Coal refineries will draw other petrochemical industries to the location spurring economic development
Initial 100 tpd is estimated to cost $21 million ($10million equity) in Asia IDC is Interest During Construction
100 tpd is estimated to yield 24% ROE
Potential Competitive Coal Conversion Technologies for FT diesel production International production from associated natural gas (flare gas) and FT diesel synthesis using Gas to Liquids (GTL Processes) requires mega gas fields. Encoal mild gasification produces a char and a reduced sulfur residual fuel oil at high cost Domestic production of FT diesel from GTL synthesis with natural gas (which is not economic with high natural gas prices in the US). Coal gasification for FT diesel production (like the Gilberton project in Pennsylvania) which is higher in capital cost and lower in ROE than Coal 21 st coal refining process. Headwaters Hydrogen Technologys expensive but high yield coal gasification to GTL or direct coal hydro-cracking with recycled heavy process liquids and use of external hydrogen (currently being licensed in China). Lower ROE than Coal21st.
Shell Gasification Markets are Really Coal to Chemicals in China?
