Abstract

Coal is till today the most commonly used fuel worldwide for electricity generation, with the largest consumers being China, USA and India respectively. Coal contains small amounts of radioactive elements such as uranium, thorium, potassium-40, radium and radon, in the range of a few parts per million, which make their removal difficult and economically unfeasible through conventional industrial technologies. The concentrations gets amplified in the coal ash (fly ash), thereby presenting environmental and human health risks. In this preliminary paper, we propose an innovative clean coal technology, namely microwave induced plasma gasification (MIPG) to turn coal into syngas, while the molten residue is sent to a microwave-heated electromagnetic plasma separator for isolation of radioactive elements. With the adoption of this technology, coal producing and consuming nations will be able to satisfy a large portion of their nuclear fuel requirements from clean coal.
