Characterizing moisture occurrence state in coal gasification fine slag filter cake using low field nuclear magnetic resonance technology

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2023
Gasification fine slag, a carbon-rich solid waste produced during coal gasification, is currently disposed of through conventional landfilling methods. Its high-water content hampers resource utilization by reducing its calorific value.
