    deep reductions in SO and nitrogen oxide ("NO ") emissions and the current and future allowance market prices have already reacted. This volatility and the high price of emissionscontrolling technologies such as scrubbers make lowsulfur coals attractive fuel sources. However the depletion of central Appalachian coal reserves and the 2005

     · broken down. Therefore an olddeep crude oil has low viscosity low density and very low sulfur content. This combination of properties makes the olddeep crudes the most desirable they require little refining to remove sulfur and they can be converted to large quantities of highquality products such as gasoline (see below).

    Market Efficiency and the Market for Sulfur Dioxide

     · Market Efficiency and the Market for Sulfur Dioxide Allowances . Abstract . Focusing on the sulfur dioxide (SO 2) allowance market from its inception (in 1994) to 2009 we model allowance prices to determine the influence of market fundamentals—such as prices of high and lowsulfur coal—on allowance price level and volatility.

    201831 · Using this process refineries that process heavy sour crude separate the sulfur from products such as gasoline gasoil and kerosene. It is worthwhile to note that the levels of sulfur in the environment have steadily increased in the past two decades due to the use of heavier crude and cheaper high sulfur

    Reduction of Sulfur Dioxide Emissions by Burning Coal

     · This study included two high and mediumsulfur bituminous coals two lowsulfur lignite coals and a subbituminous coal. Results showed that bituminous coals burning under substoichiometric (fuellean) conditions release most of their sulfur content in the form of SO 2 gases whereas lowranked coals only partly release their sulfur as SO 2.

     · The coal industry serves a vital role in the nation s economy by producing fuel for more than half of its electricity. Despite the industry s importance industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2

Coal resources within the state are found in three key areas the Bowen Basin Surat Basin and the Galilee Basin in which the proposed Mine is situated. The Galilee Basin spans over 247 000 km2 of land and contains coal resources that are largely highvolatility lowsulphur thermal coal of Permian age.

     · Abundance of sulfur in coal is controlled by depositional environment and the diagenesis of the coal seams and overlying strata. Typical low sulfur coal seams were deposited in an alluvial (deltaic) environment and the peat was not influenced by seawater. The sulfur in these lowsulfur coals is derived mostly from its parent plant materials.

Some coals however have ash with lower melting temperatures and high amounts of components that can contribute to high ash deposition rates.

    CoalThe NEED Project

     · Coal companies look for lowsulfur coal to mine. They work hard to remove sulfur and other impurities from the coal. Power plants install machines called scrubbers to remove most of the sulfur from coal smoke so it doesn t get into the air. Other byproducts like the ash that is left after coal is burned once were sent to landfills.

    Recent advances of sodium borohydride reduction in coal

    As mentioned above Li proposed a new desulfurization process with sodium borohydride reduction for highsulfur coals. 19 After that we researched the use of NaBH 4 for deep desulfurization of CWS and gasoline in depth and the common influencing factors such as reductant (NaBH 4) concentration treatment time coal particle size reaction

The subbituminous types of coals from NorthEastern region (NER) India contain high sulfur (∼2–8 ) with the majority of sulfur being organically bound and low ash content. The physicochemical properties of these coals are abnormal in comparison to the other similar types of coals in the world.
