Leading Edge of Coal Utilization Technologies for Gasification and Cokemaking

Abstract

Coal is a very important resource for power generation and cokemaking. Moreover, coal is a very useful resource for producing city gas and chemical materials by gasification technology. Low grade coals are suitable for the coal gasification resources because they are easily decomposed and converted to generate gas in the gasifier. On the other hand, high quality coals such as good quality bituminous coals are required for producing metallurgical coke. Recently, the amount of high quality coals has been decreasing. The expansion of raw coal brands for producing metallurgical coke is very important. In this paper, the development of high energy efficiency gasification technology, ECORO^®, and new cokemaking technologies such as the DAPS and the SCOPE21 enabling the expansion of coal resources are introduced. These technologies are contributed to the expansion of coal resources and energy savings.
