— Fine slag FS consists of residual carbon RC and slag particles SP This paper studies the characteristics of SP and RC separately One of these studies prepared the slag particles using the ashing treatment at 600 °C and for 24 h in a muffle furnace and this treatment could change their original properties and lead to inaccurate
Coal gasification fine slag is one of the by products from clean and efficient utilization of coal and its resource utilization is extremely urgent In this work a high carbon fraction with a fixed carbon content higher than 60% was obtained by simple sieving of gasification fine slag from which a porous material was prepared by ultrasonic acid leaching method The
