Characterization, carbon-ash separation and resource utilization of coal gasification fine slag: A comprehensive review
East China University of Science and Technology · Ningxia University
Abstract
Coal gasification fine slag (CGFS) from the entrained-flow coal gasification process mainly contains ash and residual carbon. Currently, the CGFS is normally stacked and landfilled in slag yards, resulting in huge resources waste and potential environmental risks. This study aims to review the research advances of the characterizations, carbon-ash separation and resource utilization of CGFS, so as to reveal the guiding role of CGFS characterizations on the process of separation and resource utilization. In this paper, the characterizations of CGFS are summarized from compositions, structures and dehydration. Methods for separating carbon-ash from CGFS are compared and analyzed. The resource utilization methods…
