Coal forms from organic material that decays and experiences pressure and heat for millions of years Since they take so long to form fossil fuels like coal and oil are nonrenewable The process N2 This paper introduces a novel process for the integration of pyrolysis and entrained flow gasification for the as mined Victorian brown coal containing 65 wt moisture An initial mild pyrolysis of coal is proposed to reduce moisture content and produce multiple products including char tar and hydrogen rich coal

Underground Coal Gasification UCG takes advantage of the same chemical reactions of coal to produce product gases as those occurring in conventional gasifier reactors The main difference is that in UCG the underground coal seam itself becomes the reactor so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface1 Obviously Refined coal is the product of the application of a coal upgrading technology that removes moisture and certain pollutants from lower rank coals such as sub bituminous and lignite brown coals and raising their calorific valu Coal refining or upgrading technologies are typically pre combustion treatments and/or processes that alter the characteristics of a coal before it is burned
