No.24 Kinetic analysis of gasification of char in a circulating fluidized bed gasifier

Abstract

Steam gasification of Indonesian low-rank coal char was kinetically analyzed on the basis of Langmuir-Hinshelwood mechanism. According to the kinetic parameters determined by L-H mechanism, inhibition of gasification of char by hydrogen gas was substantial. The extent of gasification of char in a gasifier of our developed circulating fluidized bed gasification system was attempted to be described by using the kinetic parameters. The gas yield in the gasifier was successfully described by the kinetic parameters.
