At the Institute of Gas Technology (IGT) significant effort has been expended to develop processes to utilize coal on an environmentally acceptable basis, including coal conversion to low- and medium-Btu gas. These grades of gas can readily be utilized in process steam boilers, industrial heat furnaces, as a local substitute for natural gas and/or fuel oil, electricity generation in combined-cycle power plants and as a feedstock for petrochemicals. The U-GAS process combines a single-stage fluidized-bed gasifier with an ash agglomerating mechanism to achieve selective removal of high-ash-bearing material (agglomerates) and high carbon conversions. To date, successful gasification tests have been conducted that achieved carbon gasification efficiencies exceeding 90% with coal and char feeds and ash agglomerates have been produced during test operations conducted with coke breeze, Illinois No. 6 bituminous coal and washed and unwashed Western Kentucky No. 9 bituminous coal. U-GAS process tests are being completed to produce design data at 60 psia (413 kPa) for an Industrial Fuel Gas Demonstration Plant.
