Gasification: An Efficient Coal Utilization Technology

Introduction Gasification of coal has been practiced for many decades for the production of gas, fuels, chemicals and power. However it has only more recently started to get significant attention in the USA. In this review of the basics the features of gasification as compared with combustion is covered and the potential of increasing the conversion of coal via gasification is indicated. After dealing with the fundamentals of gasification a review of gasification technologies will be presented with an indication of the widespread international and more limited US use of this technology. In conclusion the attention will be directed at the future prospects of gasification.
