Since 1974, Battelle has been developing a catalytic treatment process that would allow more economic, efficient and reliable utilization of the vast deposits of eastern coals in gasification systems. In order to keep the process simple and economic, a disposable catalyst lime (CaO), was employed. It was found that the effectiveness of low concentrations of CaO was greatly increased by thorough incorporation into the coal. As a result of these efforts, a catalytic treatment system has been developed that promises to allow simplifications and improvements in existing commercial gasification processes as well as advanced gasification systems. One gasification system that appears exceptionally attractive utilizing the treatment system is direct fluid-bed hydrogasification or hydropyrolysis. A simple pressurized fluid-bed steam/oxygen gasification system is also an attractive option which could be commercialized quickly. Data generated under this program demonstrated the technical and economic advantages of these approaches.
