Gasification of Hybrid Particles of Gasification and Liquefaction Residue of Coal

Abstract

Hybrid particles of coal ash from gasifier and higher viscous residue and solid pitch from coal liquefaction were successfully produced by two new methods. They were then gasified by steam and oxygen in a fluidized bed under atmospheric pressure. Gasification characteristics of these particles, such as the distribution and yield of gas produced and the carbon conversion, were evaluated as a function of operating variables.
