Abstract

Abstract

This is an article in the field of mineral processing engineering. The gasification slag is a by-product produced in the process of coal gasification, which is difficult to be industrialized. In order to realize the rational and effective utilization of gasification slags, the gasification coarse slags produced by the typical coal water slurry process in Ordos area of China are simply separated into high, medium and low carbon slags by screening. The physicochemical properties, heavy metal content, carbon content, micro morphology, mineral phase composition and pore structure of the three types of carbon slags were characterized and analyzed by XRF, element analyzer, XRD, SEM, BET specific surface area analyzer, thermogravimetric analyzer and ICP-MS. The high, medium and low carbon slags have significant differences in characteristics. The screening can better realize the preliminary quality separation of gasified slags, which lays a foundation for the classified utilization of gasified slags.
